Page
Page provides methods to interact with a single tab in a Browser, or an extension background page in Chromium. One Browser instance might have multiple Page instances.
This example creates a page, navigates it to a URL, and then saves a screenshot:
playwright.webkit.launch do |browser|
page = browser.new_page
page.goto('https://example.com/')
page.screenshot(path: 'screenshot.png')
end
The Page class emits various events (described below) which can be handled using any of Node's native
EventEmitter
methods, such as on
, once
or
removeListener
.
This example logs a message for a single page load
event:
page.once("load", -> (page) { puts "page loaded!" })
To unsubscribe from events use the removeListener
method:
listener = -> (req) { puts "a request was made: #{req.url}" }
page.on('request', listener)
page.goto('https://example.com/') # => prints 'a request was made: https://example.com/'
page.off('request', listener)
page.goto('https://example.com/') # => no print
add_init_script
def add_init_script(path: nil, script: nil)
Adds a script which would be evaluated in one of the following scenarios:
- Whenever the page is navigated.
- Whenever the child frame is attached or navigated. In this case, the script is evaluated in the context of the newly attached frame.
The script is evaluated after the document was created but before any of its scripts were run. This is useful to amend
the JavaScript environment, e.g. to seed Math.random
.
Usage
An example of overriding Math.random
before the page loads:
# in your playwright script, assuming the preload.js file is in same directory
page.add_init_script(path: "./preload.js")
NOTE: The order of evaluation of multiple scripts installed via BrowserContext#add_init_script and Page#add_init_script is not defined.
add_script_tag
def add_script_tag(content: nil, path: nil, type: nil, url: nil)
Adds a <script>
tag into the page with the desired url or content. Returns the added tag when the script's onload
fires or when the script content was injected into frame.
add_style_tag
def add_style_tag(content: nil, path: nil, url: nil)
Adds a <link rel="stylesheet">
tag into the page with the desired url or a <style type="text/css">
tag with the
content. Returns the added tag when the stylesheet's onload fires or when the CSS content was injected into frame.
bring_to_front
def bring_to_front
Brings page to front (activates tab).
check
def check(
selector,
force: nil,
noWaitAfter: nil,
position: nil,
strict: nil,
timeout: nil,
trial: nil)
This method checks an element matching selector
by performing the following steps:
- Find an element matching
selector
. If there is none, wait until a matching element is attached to the DOM. - Ensure that matched element is a checkbox or a radio input. If not, this method throws. If the element is already checked, this method returns immediately.
- Wait for actionability checks on the matched element, unless
force
option is set. If the element is detached during the checks, the whole action is retried. - Scroll the element into view if needed.
- Use Page#mouse to click in the center of the element.
- Ensure that the element is now checked. If not, this method throws.
When all steps combined have not finished during the specified timeout
, this method throws a
TimeoutError
. Passing zero timeout disables this.
click
def click(
selector,
button: nil,
clickCount: nil,
delay: nil,
force: nil,
modifiers: nil,
noWaitAfter: nil,
position: nil,
strict: nil,
timeout: nil,
trial: nil)
This method clicks an element matching selector
by performing the following steps:
- Find an element matching
selector
. If there is none, wait until a matching element is attached to the DOM. - Wait for actionability checks on the matched element, unless
force
option is set. If the element is detached during the checks, the whole action is retried. - Scroll the element into view if needed.
- Use Page#mouse to click in the center of the element, or the specified
position
. - Wait for initiated navigations to either succeed or fail, unless
noWaitAfter
option is set.
When all steps combined have not finished during the specified timeout
, this method throws a
TimeoutError
. Passing zero timeout disables this.
close
def close(reason: nil, runBeforeUnload: nil)
If runBeforeUnload
is false
, does not run any unload handlers and waits for the page to be closed. If
runBeforeUnload
is true
the method will run unload handlers, but will not wait for the page to close.
By default, page.close()
does not run beforeunload
handlers.
NOTE: if runBeforeUnload
is passed as true, a beforeunload
dialog might be summoned and should be handled
manually via [event: Page.dialog
] event.
content
def content
Gets the full HTML contents of the page, including the doctype.
context
def context
Get the browser context that the page belongs to.
dblclick
def dblclick(
selector,
button: nil,
delay: nil,
force: nil,
modifiers: nil,
noWaitAfter: nil,
position: nil,
strict: nil,
timeout: nil,
trial: nil)
This method double clicks an element matching selector
by performing the following steps:
- Find an element matching
selector
. If there is none, wait until a matching element is attached to the DOM. - Wait for actionability checks on the matched element, unless
force
option is set. If the element is detached during the checks, the whole action is retried. - Scroll the element into view if needed.
- Use Page#mouse to double click in the center of the element, or the specified
position
.
When all steps combined have not finished during the specified timeout
, this method throws a
TimeoutError
. Passing zero timeout disables this.
NOTE: page.dblclick()
dispatches two click
events and a single dblclick
event.
dispatch_event
def dispatch_event(
selector,
type,
eventInit: nil,
strict: nil,
timeout: nil)
The snippet below dispatches the click
event on the element. Regardless of the visibility state of the element, click
is dispatched. This is equivalent to calling
element.click().
Usage
page.content = '<button id="submit">Send</button>'
page.dispatch_event("button#submit", "click")
Under the hood, it creates an instance of an event based on the given type
, initializes it with
eventInit
properties and dispatches it on the element. Events are composed
, cancelable
and bubble by
default.
Since eventInit
is event-specific, please refer to the events documentation for the lists of initial
properties:
- DeviceMotionEvent
- DeviceOrientationEvent
- DragEvent
- Event
- FocusEvent
- KeyboardEvent
- MouseEvent
- PointerEvent
- TouchEvent
- WheelEvent
You can also specify JSHandle as the property value if you want live objects to be passed into the event:
page.content = '<div id="source">Drag</div>'
# note you can only create data_transfer in chromium and firefox
data_transfer = page.evaluate_handle("new DataTransfer()")
page.dispatch_event("#source", "dragstart", eventInit: { dataTransfer: data_transfer })
drag_and_drop
def drag_and_drop(
source,
target,
force: nil,
noWaitAfter: nil,
sourcePosition: nil,
strict: nil,
targetPosition: nil,
timeout: nil,
trial: nil)
This method drags the source element to the target element.
It will first move to the source element, perform a mousedown
,
then move to the target element and perform a mouseup
.
Usage
page.drag_and_drop("#source", "#target")
# or specify exact positions relative to the top-left corners of the elements:
page.drag_and_drop(
"#source",
"#target",
sourcePosition: { x: 34, y: 7 },
targetPosition: { x: 10, y: 20 },
)
emulate_media
def emulate_media(colorScheme: nil, forcedColors: nil, media: nil, reducedMotion: nil)
This method changes the CSS media type
through the media
argument, and/or the 'prefers-colors-scheme'
media feature, using the colorScheme
argument.
Usage
page.evaluate("matchMedia('screen').matches") # => true
page.evaluate("matchMedia('print').matches") # => false
page.emulate_media(media: "print")
page.evaluate("matchMedia('screen').matches") # => false
page.evaluate("matchMedia('print').matches") # => true
page.emulate_media
page.evaluate("matchMedia('screen').matches") # => true
page.evaluate("matchMedia('print').matches") # => false
page.emulate_media(colorScheme: "dark")
page.evaluate("matchMedia('(prefers-color-scheme: dark)').matches") # => true
page.evaluate("matchMedia('(prefers-color-scheme: light)').matches") # => false
eval_on_selector
def eval_on_selector(selector, expression, arg: nil, strict: nil)
The method finds an element matching the specified selector within the page and passes it as a first argument to
expression
. If no elements match the selector, the method throws an error. Returns the value of
expression
.
If expression
returns a Promise, then Page#eval_on_selector would wait for the promise to resolve and
return its value.
Usage
search_value = page.eval_on_selector("#search", "el => el.value")
preload_href = page.eval_on_selector("link[rel=preload]", "el => el.href")
html = page.eval_on_selector(".main-container", "(e, suffix) => e.outer_html + suffix", arg: "hello")
eval_on_selector_all
def eval_on_selector_all(selector, expression, arg: nil)
The method finds all elements matching the specified selector within the page and passes an array of matched elements as
a first argument to expression
. Returns the result of expression
invocation.
If expression
returns a Promise, then Page#eval_on_selector_all would wait for the promise to resolve and
return its value.
Usage
div_counts = page.eval_on_selector_all("div", "(divs, min) => divs.length >= min", arg: 10)
evaluate
def evaluate(expression, arg: nil)
Returns the value of the expression
invocation.
If the function passed to the Page#evaluate returns a Promise, then Page#evaluate would wait for the promise to resolve and return its value.
If the function passed to the Page#evaluate returns a non-Serializable value, then
Page#evaluate resolves to undefined
. Playwright also supports transferring some
additional values that are not serializable by JSON
: -0
, NaN
, Infinity
, -Infinity
.
Usage
Passing argument to expression
:
result = page.evaluate("([x, y]) => Promise.resolve(x * y)", arg: [7, 8])
puts result # => "56"
A string can also be passed in instead of a function:
puts page.evaluate("1 + 2") # => 3
x = 10
puts page.evaluate("1 + #{x}") # => "11"
ElementHandle instances can be passed as an argument to the Page#evaluate:
body_handle = page.query_selector("body")
html = page.evaluate("([body, suffix]) => body.innerHTML + suffix", arg: [body_handle, "hello"])
body_handle.dispose
evaluate_handle
def evaluate_handle(expression, arg: nil)
Returns the value of the expression
invocation as a JSHandle.
The only difference between Page#evaluate and Page#evaluate_handle is that Page#evaluate_handle returns JSHandle.
If the function passed to the Page#evaluate_handle returns a Promise, then Page#evaluate_handle would wait for the promise to resolve and return its value.
Usage
a_window_handle = page.evaluate_handle("Promise.resolve(window)")
a_window_handle # handle for the window object.
A string can also be passed in instead of a function:
a_handle = page.evaluate_handle("document") # handle for the "document"
JSHandle instances can be passed as an argument to the Page#evaluate_handle:
body_handle = page.evaluate_handle("document.body")
result_handle = page.evaluate_handle("body => body.innerHTML", arg: body_handle)
puts result_handle.json_value
result_handle.dispose
expose_binding
def expose_binding(name, callback, handle: nil)
The method adds a function called name
on the window
object of every frame in this page. When called, the
function executes callback
and returns a Promise which resolves to the return value of callback
.
If the callback
returns a Promise, it will be awaited.
The first argument of the callback
function contains information about the caller: { browserContext: BrowserContext, page: Page, frame: Frame }
.
See BrowserContext#expose_binding for the context-wide version.
NOTE: Functions installed via Page#expose_binding survive navigations.
Usage
An example of exposing page URL to all frames in a page:
page.expose_binding("pageURL", ->(source) { source[:page].url })
page.content = <<~HTML
<script>
async function onClick() {
document.querySelector('div').textContent = await window.pageURL();
}
</script>
<button onclick="onClick()">Click me</button>
<div></div>
HTML
page.click("button")
expose_function
def expose_function(name, callback)
The method adds a function called name
on the window
object of every frame in the page. When called, the
function executes callback
and returns a Promise which resolves to the return value of callback
.
If the callback
returns a Promise, it will be awaited.
See BrowserContext#expose_function for context-wide exposed function.
NOTE: Functions installed via Page#expose_function survive navigations.
Usage
An example of adding a sha256
function to the page:
require 'digest'
def sha256(text)
Digest::SHA256.hexdigest(text)
end
page.expose_function("sha256", method(:sha256))
page.content = <<~HTML
<script>
async function onClick() {
document.querySelector('div').textContent = await window.sha256('PLAYWRIGHT');
}
</script>
<button onclick="onClick()">Click me</button>
<div></div>
HTML
page.locator("button").click
fill
def fill(
selector,
value,
force: nil,
noWaitAfter: nil,
strict: nil,
timeout: nil)
This method waits for an element matching selector
, waits for actionability checks, focuses the element, fills it and triggers an input
event after filling. Note that you can pass an empty string to clear the input field.
If the target element is not an <input>
, <textarea>
or [contenteditable]
element, this method throws an error. However, if the element is inside the <label>
element that has an associated control, the control will be filled instead.
To send fine-grained keyboard events, use Locator#press_sequentially.
focus
def focus(selector, strict: nil, timeout: nil)
This method fetches an element with selector
and focuses it. If there's no element matching
selector
, the method waits until a matching element appears in the DOM.
frame
def frame(name: nil, url: nil)
Returns frame matching the specified criteria. Either name
or url
must be specified.
Usage
frame = page.frame(name: "frame-name")
frame = page.frame(url: /.*domain.*/)
frame_locator
def frame_locator(selector)
When working with iframes, you can create a frame locator that will enter the iframe and allow selecting elements in that iframe.
Usage
Following snippet locates element with text "Submit" in the iframe with id my-frame
,
like <iframe id="my-frame">
:
locator = page.frame_locator("#my-iframe").get_by_text("Submit")
locator.click
frames
def frames
An array of all frames attached to the page.
get_attribute
def get_attribute(selector, name, strict: nil, timeout: nil)
Returns element attribute value.
get_by_alt_text
def get_by_alt_text(text, exact: nil)
Allows locating elements by their alt text.
Usage
For example, this method will find the image by alt text "Playwright logo":
<img alt='Playwright logo'>
page.get_by_alt_text("Playwright logo").click
get_by_label
def get_by_label(text, exact: nil)
Allows locating input elements by the text of the associated <label>
or aria-labelledby
element, or by the aria-label
attribute.
Usage
For example, this method will find inputs by label "Username" and "Password" in the following DOM:
<input aria-label="Username">
<label for="password-input">Password:</label>
<input id="password-input">
page.get_by_label("Username").fill("john")
page.get_by_label("Password").fill("secret")
get_by_placeholder
def get_by_placeholder(text, exact: nil)
Allows locating input elements by the placeholder text.
Usage
For example, consider the following DOM structure.
<input type="email" placeholder="name@example.com" />
You can fill the input after locating it by the placeholder text:
page.get_by_placeholder("name@example.com").fill("playwright@microsoft.com")
get_by_role
def get_by_role(
role,
checked: nil,
disabled: nil,
exact: nil,
expanded: nil,
includeHidden: nil,
level: nil,
name: nil,
pressed: nil,
selected: nil)
Allows locating elements by their ARIA role, ARIA attributes and accessible name.
Usage
Consider the following DOM structure.
<h3>Sign up</h3>
<label>
<input type="checkbox" /> Subscribe
</label>
<br/>
<button>Submit</button>
You can locate each element by it's implicit role:
page.get_by_role("heading", name: "Sign up").visible? # => true
page.get_by_role("checkbox", name: "Subscribe").check
page.get_by_role("button", name: /submit/i).click
Details
Role selector does not replace accessibility audits and conformance tests, but rather gives early feedback about the ARIA guidelines.
Many html elements have an implicitly defined role that is recognized by the role selector. You can find all the supported roles here. ARIA guidelines do not recommend duplicating implicit roles and attributes by setting role
and/or aria-*
attributes to default values.
get_by_test_id
def get_by_test_id(testId)
Locate element by the test id.
Usage
Consider the following DOM structure.
<button data-testid="directions">Itinéraire</button>
You can locate the element by it's test id:
page.get_by_test_id("directions").click
Details
By default, the data-testid
attribute is used as a test id. Use Selectors#set_test_id_attribute to configure a different test id attribute if necessary.
get_by_text
def get_by_text(text, exact: nil)
Allows locating elements that contain given text.
See also Locator#filter that allows to match by another criteria, like an accessible role, and then filter by the text content.
Usage
Consider the following DOM structure:
<div>Hello <span>world</span></div>
<div>Hello</div>
You can locate by text substring, exact string, or a regular expression:
page.content = <<~HTML
<div>Hello <span>world</span></div>
<div>Hello</div>
HTML
# Matches <span>
locator = page.get_by_text("world")
expect(locator.evaluate('e => e.outerHTML')).to eq('<span>world</span>')
# Matches first <div>
locator = page.get_by_text("Hello world")
expect(locator.evaluate('e => e.outerHTML')).to eq('<div>Hello <span>world</span></div>')
# Matches second <div>
locator = page.get_by_text("Hello", exact: true)
expect(locator.evaluate('e => e.outerHTML')).to eq('<div>Hello</div>')
# Matches both <div>s
locator = page.get_by_text(/Hello/)
expect(locator.count).to eq(2)
expect(locator.first.evaluate('e => e.outerHTML')).to eq('<div>Hello <span>world</span></div>')
expect(locator.last.evaluate('e => e.outerHTML')).to eq('<div>Hello</div>')
# Matches second <div>
locator = page.get_by_text(/^hello$/i)
expect(locator.evaluate('e => e.outerHTML')).to eq('<div>Hello</div>')
Details
Matching by text always normalizes whitespace, even with exact match. For example, it turns multiple spaces into one, turns line breaks into spaces and ignores leading and trailing whitespace.
Input elements of the type button
and submit
are matched by their value
instead of the text content. For example, locating by text "Log in"
matches <input type=button value="Log in">
.
get_by_title
def get_by_title(text, exact: nil)
Allows locating elements by their title attribute.
Usage
Consider the following DOM structure.
<span title='Issues count'>25 issues</span>
You can check the issues count after locating it by the title text:
page.get_by_title("Issues count").text_content # => "25 issues"
go_back
def go_back(timeout: nil, waitUntil: nil)
Returns the main resource response. In case of multiple redirects, the navigation will resolve with the response of the
last redirect. If cannot go back, returns null
.
Navigate to the previous page in history.
go_forward
def go_forward(timeout: nil, waitUntil: nil)
Returns the main resource response. In case of multiple redirects, the navigation will resolve with the response of the
last redirect. If cannot go forward, returns null
.
Navigate to the next page in history.
goto
def goto(url, referer: nil, timeout: nil, waitUntil: nil)
Returns the main resource response. In case of multiple redirects, the navigation will resolve with the first non-redirect response.
The method will throw an error if:
- there's an SSL error (e.g. in case of self-signed certificates).
- target URL is invalid.
- the
timeout
is exceeded during navigation. - the remote server does not respond or is unreachable.
- the main resource failed to load.
The method will not throw an error when any valid HTTP status code is returned by the remote server, including 404 "Not Found" and 500 "Internal Server Error". The status code for such responses can be retrieved by calling Response#status.
NOTE: The method either throws an error or returns a main resource response. The only exceptions are navigation to
about:blank
or navigation to the same URL with a different hash, which would succeed and return null
.
NOTE: Headless mode doesn't support navigation to a PDF document. See the upstream issue.
hover
def hover(
selector,
force: nil,
modifiers: nil,
noWaitAfter: nil,
position: nil,
strict: nil,
timeout: nil,
trial: nil)
This method hovers over an element matching selector
by performing the following steps:
- Find an element matching
selector
. If there is none, wait until a matching element is attached to the DOM. - Wait for actionability checks on the matched element, unless
force
option is set. If the element is detached during the checks, the whole action is retried. - Scroll the element into view if needed.
- Use Page#mouse to hover over the center of the element, or the specified
position
.
When all steps combined have not finished during the specified timeout
, this method throws a
TimeoutError
. Passing zero timeout disables this.
inner_html
def inner_html(selector, strict: nil, timeout: nil)
Returns element.innerHTML
.
inner_text
def inner_text(selector, strict: nil, timeout: nil)
Returns element.innerText
.
input_value
def input_value(selector, strict: nil, timeout: nil)
Returns input.value
for the selected <input>
or <textarea>
or <select>
element.
Throws for non-input elements. However, if the element is inside the <label>
element that has an associated control, returns the value of the control.
checked?
def checked?(selector, strict: nil, timeout: nil)
Returns whether the element is checked. Throws if the element is not a checkbox or radio input.
closed?
def closed?
Indicates that the page has been closed.
disabled?
def disabled?(selector, strict: nil, timeout: nil)
Returns whether the element is disabled, the opposite of enabled.
editable?
def editable?(selector, strict: nil, timeout: nil)
Returns whether the element is editable.
enabled?
def enabled?(selector, strict: nil, timeout: nil)
Returns whether the element is enabled.
hidden?
def hidden?(selector, strict: nil, timeout: nil)
Returns whether the element is hidden, the opposite of visible. selector
that does not match any elements is considered hidden.
visible?
def visible?(selector, strict: nil, timeout: nil)
Returns whether the element is visible. selector
that does not match any elements is considered not visible.
locator
def locator(
selector,
has: nil,
hasNot: nil,
hasNotText: nil,
hasText: nil)
The method returns an element locator that can be used to perform actions on this page / frame. Locator is resolved to the element immediately before performing an action, so a series of actions on the same locator can in fact be performed on different DOM elements. That would happen if the DOM structure between those actions has changed.
main_frame
def main_frame
The page's main frame. Page is guaranteed to have a main frame which persists during navigations.
opener
def opener
Returns the opener for popup pages and null
for others. If the opener has been closed already the returns null
.
pause
def pause
Pauses script execution. Playwright will stop executing the script and wait for the user to either press 'Resume'
button in the page overlay or to call playwright.resume()
in the DevTools console.
User can inspect selectors or perform manual steps while paused. Resume will continue running the original script from the place it was paused.
NOTE: This method requires Playwright to be started in a headed mode, with a falsy headless
option.
pdf
def pdf(
displayHeaderFooter: nil,
footerTemplate: nil,
format: nil,
headerTemplate: nil,
height: nil,
landscape: nil,
margin: nil,
outline: nil,
pageRanges: nil,
path: nil,
preferCSSPageSize: nil,
printBackground: nil,
scale: nil,
tagged: nil,
width: nil)
Returns the PDF buffer.
NOTE: Generating a pdf is currently only supported in Chromium headless.
page.pdf()
generates a pdf of the page with print
css media. To generate a pdf with screen
media, call
Page#emulate_media before calling page.pdf()
:
NOTE: By default, page.pdf()
generates a pdf with modified colors for printing. Use the
-webkit-print-color-adjust
property to
force rendering of exact colors.
Usage
# generates a pdf with "screen" media type.
page.emulate_media(media: "screen")
page.pdf(path: "page.pdf")
The width
, height
, and margin
options accept values labeled with units. Unlabeled
values are treated as pixels.
A few examples:
page.pdf({width: 100})
- prints with width set to 100 pixelspage.pdf({width: '100px'})
- prints with width set to 100 pixelspage.pdf({width: '10cm'})
- prints with width set to 10 centimeters.
All possible units are:
px
- pixelin
- inchcm
- centimetermm
- millimeter
The format
options are:
Letter
: 8.5in x 11inLegal
: 8.5in x 14inTabloid
: 11in x 17inLedger
: 17in x 11inA0
: 33.1in x 46.8inA1

: 8.27in x 11.7inA5
: 5.83in x 8.27inA6
: 4.13in x 5.83in
NOTE: headerTemplate
and footerTemplate
markup have the following limitations: > 1. Script tags inside
templates are not evaluated. > 2. Page styles are not visible inside templates.
press
def press(
selector,
key,
delay: nil,
noWaitAfter: nil,
strict: nil,
timeout: nil)
Focuses the element, and then uses Keyboard#down and Keyboard#up.
key
can specify the intended
keyboardEvent.key value or a single character to
generate the text for. A superset of the key
values can be found
here. Examples of the keys are:
F1
- F12
, Digit0
- Digit9
, KeyA
- KeyZ
, Backquote
, Minus
, Equal
, Backslash
, Backspace
, Tab
,
Delete
, Escape
, ArrowDown
, End
, Enter
, Home
, Insert
, PageDown
, PageUp
, ArrowRight
, ArrowUp
, etc.
Following modification shortcuts are also supported: Shift
, Control
, Alt
, Meta
, ShiftLeft
, ControlOrMeta
.
ControlOrMeta
resolves to Control
on Windows and Linux and to Meta
on macOS.
Holding down Shift
will type the text that corresponds to the key
in the upper case.
If key
is a single character, it is case-sensitive, so the values a
and A
will generate different
respective texts.
Shortcuts such as key: "Control+o"
, key: "Control++
or key: "Control+Shift+T"
are supported as well. When specified with the
modifier, modifier is pressed and being held while the subsequent key is being pressed.
Usage
page.goto("https://keycode.info")
page.press("body", "A")
page.screenshot(path: "a.png")
page.press("body", "ArrowLeft")
page.screenshot(path: "arrow_left.png")
page.press("body", "Shift+O")
page.screenshot(path: "o.png")
query_selector
def query_selector(selector, strict: nil)
The method finds an element matching the specified selector within the page. If no elements match the selector, the
return value resolves to null
. To wait for an element on the page, use Locator#wait_for.
query_selector_all
def query_selector_all(selector)
The method finds all elements matching the specified selector within the page. If no elements match the selector, the
return value resolves to []
.
reload
def reload(timeout: nil, waitUntil: nil)
This method reloads the current page, in the same way as if the user had triggered a browser refresh. Returns the main resource response. In case of multiple redirects, the navigation will resolve with the response of the last redirect.
route
def route(url, handler, times: nil)
Routing provides the capability to modify network requests that are made by a page.
Once routing is enabled, every request matching the url pattern will stall unless it's continued, fulfilled or aborted.
NOTE: The handler will only be called for the first url if the response is a redirect.
NOTE: Page#route will not intercept requests intercepted by Service Worker. See this issue. We recommend disabling Service Workers when using request interception by setting serviceWorkers
to 'block'
.
NOTE: Page#route will not intercept the first request of a popup page. Use BrowserContext#route instead.
Usage
An example of a naive handler that aborts all image requests:
page.route("**/*.{png,jpg,jpeg}", ->(route, request) { route.abort })
page.goto("https://example.com")
or the same snippet using a regex pattern instead:
page.route(/\.(png|jpg)$/, ->(route, request) { route.abort })
page.goto("https://example.com")
It is possible to examine the request to decide the route action. For example, mocking all requests that contain some post data, and leaving all other requests as is:
def handle_route(route, request)
if request.post_data["my-string"]
mocked_data = request.post_data.merge({ "my-string" => 'mocked-data'})
route.fulfill(postData: mocked_data)
else
route.continue
end
end
page.route("/api/**", method(:handle_route))
Page routes take precedence over browser context routes (set up with BrowserContext#route) when request matches both handlers.
To remove a route with its handler you can use Page#unroute.
NOTE: Enabling routing disables http cache.
route_from_har
def route_from_har(
har,
notFound: nil,
update: nil,
updateContent: nil,
updateMode: nil,
url: nil)
If specified the network requests that are made in the page will be served from the HAR file. Read more about Replaying from HAR.
Playwright will not serve requests intercepted by Service Worker from the HAR file. See this issue. We recommend disabling Service Workers when using request interception by setting serviceWorkers
to 'block'
.
screenshot
def screenshot(
animations: nil,
caret: nil,
clip: nil,
fullPage: nil,
mask: nil,
maskColor: nil,
omitBackground: nil,
path: nil,
quality: nil,
scale: nil,

Returns the buffer with the captured screenshot.
select_option
def select_option(
selector,
element: nil,
index: nil,
value: nil,
label: nil,
force: nil,
noWaitAfter: nil,
strict: nil,
timeout: nil)
This method waits for an element matching selector
, waits for actionability checks, waits until all specified options are present in the <select>
element and selects these options.
If the target element is not a <select>
element, this method throws an error. However, if the element is inside the <label>
element that has an associated control, the control will be used instead.
Returns the array of option values that have been successfully selected.
Triggers a change
and input
event once all the provided options have been selected.
Usage
# single selection matching the value
page.select_option("select#colors", value: "blue")
# single selection matching both the label
page.select_option("select#colors", label: "blue")
# multiple selection
page.select_option("select#colors", value: ["red", "green", "blue"])
set_checked
def set_checked(
selector,
checked,
force: nil,
noWaitAfter: nil,
position: nil,
strict: nil,
timeout: nil,
trial: nil)
This method checks or unchecks an element matching selector
by performing the following steps:
- Find an element matching
selector
. If there is none, wait until a matching element is attached to the DOM. - Ensure that matched element is a checkbox or a radio input. If not, this method throws.
- If the element already has the right checked state, this method returns immediately.
- Wait for actionability checks on the matched element, unless
force
option is set. If the element is detached during the checks, the whole action is retried. - Scroll the element into view if needed.
- Use Page#mouse to click in the center of the element.
- Ensure that the element is now checked or unchecked. If not, this method throws.
When all steps combined have not finished during the specified timeout
, this method throws a
TimeoutError
. Passing zero timeout disables this.
set_content
def set_content(html, timeout: nil, waitUntil: nil)
alias: content=
This method internally calls document.write(), inheriting all its specific characteristics and behaviors.
set_default_navigation_timeout
def set_default_navigation_timeout(timeout)
alias: default_navigation_timeout=
This setting will change the default maximum navigation time for the following methods and related shortcuts:
- Page#go_back
- Page#go_forward
- Page#goto
- Page#reload
- Page#set_content
- Page#expect_navigation
- Page#wait_for_url
NOTE: Page#set_default_navigation_timeout takes priority over Page#set_default_timeout, BrowserContext#set_default_timeout and BrowserContext#set_default_navigation_timeout.
set_default_timeout
def set_default_timeout(timeout)
alias: default_timeout=
This setting will change the default maximum time for all the methods accepting timeout
option.
NOTE: Page#set_default_navigation_timeout takes priority over Page#set_default_timeout.
set_extra_http_headers
def set_extra_http_headers(headers)
alias: extra_http_headers=
The extra HTTP headers will be sent with every request the page initiates.
NOTE: Page#set_extra_http_headers does not guarantee the order of headers in the outgoing requests.
set_input_files
def set_input_files(
selector,
files,
noWaitAfter: nil,
strict: nil,
timeout: nil)
Sets the value of the file input to these file paths or files. If some of the filePaths
are relative paths, then they
are resolved relative to the current working directory. For empty array, clears the selected files.
For inputs with a [webkitdirectory]
attribute, only a single directory path is supported.
This method expects selector
to point to an
input element. However, if the element is inside the <label>
element that has an associated control, targets the control instead.
set_viewport_size
def set_viewport_size(viewportSize)
alias: viewport_size=
In the case of multiple pages in a single browser, each page can have its own viewport size. However, Browser#new_context allows to set viewport size (and more) for all pages in the context at once.
Page#set_viewport_size will resize the page. A lot of websites don't expect phones to change size, so you should set the
viewport size before navigating to the page. Page#set_viewport_size will also reset screen
size, use Browser#new_context with screen
and viewport
parameters if you need better control of these properties.
Usage
page.viewport_size = { width: 640, height: 480 }
page.goto("https://example.com")
tap_point
def tap_point(
selector,
force: nil,
modifiers: nil,
noWaitAfter: nil,
position: nil,
strict: nil,
timeout: nil,
trial: nil)
This method taps an element matching selector
by performing the following steps:
- Find an element matching
selector
. If there is none, wait until a matching element is attached to the DOM. - Wait for actionability checks on the matched element, unless
force
option is set. If the element is detached during the checks, the whole action is retried. - Scroll the element into view if needed.
- Use Page#touchscreen to tap the center of the element, or the specified
position
.
When all steps combined have not finished during the specified timeout
, this method throws a
TimeoutError
. Passing zero timeout disables this.
NOTE: Page#tap_point the method will throw if hasTouch
option of the browser context is false.
text_content
def text_content(selector, strict: nil, timeout: nil)
Returns element.textContent
.
title
def title
Returns the page's title.
type
def type(
selector,
text,
delay: nil,
noWaitAfter: nil,
strict: nil,
timeout: nil)
In most cases, you should use Locator#fill instead. You only need to press keys one by one if there is special keyboard handling on the page - in this case use Locator#press_sequentially.
Sends a keydown
, keypress
/input
, and keyup
event for each character in the text. page.type
can be used to send
fine-grained keyboard events. To fill values in form fields, use Page#fill.
To press a special key, like Control
or ArrowDown
, use Keyboard#press.
Usage
uncheck
def uncheck(
selector,
force: nil,
noWaitAfter: nil,
position: nil,
strict: nil,
timeout: nil,
trial: nil)
This method unchecks an element matching selector
by performing the following steps:
- Find an element matching
selector
. If there is none, wait until a matching element is attached to the DOM. - Ensure that matched element is a checkbox or a radio input. If not, this method throws. If the element is already unchecked, this method returns immediately.
- Wait for actionability checks on the matched element, unless
force
option is set. If the element is detached during the checks, the whole action is retried. - Scroll the element into view if needed.
- Use Page#mouse to click in the center of the element.
- Ensure that the element is now unchecked. If not, this method throws.
When all steps combined have not finished during the specified timeout
, this method throws a
TimeoutError
. Passing zero timeout disables this.
unroute_all
def unroute_all(behavior: nil)
Removes all routes created with Page#route and Page#route_from_har.
unroute
def unroute(url, handler: nil)
Removes a route created with Page#route. When handler
is not specified, removes all routes for
the url
.
url
def url
video
def video
Video object associated with this page.
viewport_size
def viewport_size
expect_console_message
def expect_console_message(predicate: nil, timeout: nil, &block)
Performs action and waits for a ConsoleMessage to be logged by in the page. If predicate is provided, it passes
ConsoleMessage value into the predicate
function and waits for predicate(message)
to return a truthy value.
Will throw an error if the page is closed before the [event: Page.console
] event is fired.
expect_download
def expect_download(predicate: nil, timeout: nil, &block)
Performs action and waits for a new Download. If predicate is provided, it passes
Download value into the predicate
function and waits for predicate(download)
to return a truthy value.
Will throw an error if the page is closed before the download event is fired.
expect_event
def expect_event(event, predicate: nil, timeout: nil, &block)
Waits for event to fire and passes its value into the predicate function. Returns when the predicate returns truthy value. Will throw an error if the page is closed before the event is fired. Returns the event data value.
Usage
frame = page.expect_event("framenavigated") do
page.get_by_role("button")
end
expect_file_chooser
def expect_file_chooser(predicate: nil, timeout: nil, &block)
Performs action and waits for a new FileChooser to be created. If predicate is provided, it passes
FileChooser value into the predicate
function and waits for predicate.call(fileChooser)
to return a truthy value.
Will throw an error if the page is closed before the file chooser is opened.
wait_for_function
def wait_for_function(expression, arg: nil, polling: nil, timeout: nil)
Returns when the expression
returns a truthy value. It resolves to a JSHandle of the truthy value.
Usage
The Page#wait_for_function can be used to observe viewport size change:
page.evaluate("window.x = 0; setTimeout(() => { window.x = 100 }, 1000);")
page.wait_for_function("() => window.x > 0")
To pass an argument to the predicate of Page#wait_for_function function:
selector = ".foo"
page.wait_for_function("selector => !!document.querySelector(selector)", arg: selector)
wait_for_load_state
def wait_for_load_state(state: nil, timeout: nil)
Returns when the required load state has been reached.
This resolves when the page reaches a required load state, load
by default. The navigation must have been committed
when this method is called. If current document has already reached the required state, resolves immediately.
NOTE: Most of the time, this method is not needed because Playwright auto-waits before every action.
Usage
page.get_by_role("button").click # click triggers navigation.
page.wait_for_load_state # the promise resolves after "load" event.
popup = page.expect_popup do
page.get_by_role("button").click # click triggers a popup.
end
# Wait for the "DOMContentLoaded" event.
popup.wait_for_load_state("domcontentloaded")
puts popup.title # popup is ready to use.
expect_navigation
def expect_navigation(timeout: nil, url: nil, waitUntil: nil, &block)
This method is inherently racy, please use Page#wait_for_url instead.
Waits for the main frame navigation and returns the main resource response. In case of multiple redirects, the navigation
will resolve with the response of the last redirect. In case of navigation to a different anchor or navigation due to
History API usage, the navigation will resolve with null
.
Usage
This resolves when the page navigates to a new URL or reloads. It is useful for when you run code which will indirectly
cause the page to navigate. e.g. The click target has an onclick
handler that triggers navigation from a setTimeout
.
Consider this example:
page.expect_navigation do
# This action triggers the navigation after a timeout.
page.get_by_text("Navigate after timeout").click
end # Resolves after navigation has finished
NOTE: Usage of the History API to change the URL is considered a navigation.
expect_popup
def expect_popup(predicate: nil, timeout: nil, &block)
Performs action and waits for a popup Page. If predicate is provided, it passes
[Popup] value into the predicate
function and waits for predicate(page)
to return a truthy value.
Will throw an error if the page is closed before the popup event is fired.
expect_request
def expect_request(urlOrPredicate, timeout: nil, &block)
Waits for the matching request and returns it. See waiting for event for more details about events.
Usage
page.content = '<form action="https://example.com/resource"><input type="submit" value="trigger request" /></form>'
request = page.expect_request(/example.com\/resource/) do
page.get_by_text("trigger request").click
end
puts request.headers
page.wait_for_load_state # wait for request finished.
# or with a predicate
page.content = '<form action="https://example.com/resource"><input type="submit" value="trigger request" /></form>'
request = page.expect_request(->(req) { req.url.start_with? 'https://example.com/resource' }) do
page.get_by_text("trigger request").click
end
puts request.headers
expect_request_finished
def expect_request_finished(predicate: nil, timeout: nil, &block)
Performs action and waits for a Request to finish loading. If predicate is provided, it passes
Request value into the predicate
function and waits for predicate(request)
to return a truthy value.
Will throw an error if the page is closed before the [event: Page.requestFinished
] event is fired.
expect_response
def expect_response(urlOrPredicate, timeout: nil, &block)
Returns the matched response. See waiting for event for more details about events.
Usage
page.content = '<form action="https://example.com/resource"><input type="submit" value="trigger response" /></form>'
response = page.expect_response(/example.com\/resource/) do
page.get_by_text("trigger response").click
end
puts response.body
puts response.ok?
page.wait_for_load_state # wait for request finished.
# or with a predicate
page.content = '<form action="https://example.com/resource"><input type="submit" value="trigger response" /></form>'
response = page.expect_response(->(res) { res.url.start_with? 'https://example.com/resource' }) do
page.get_by_text("trigger response").click
end
puts response.body
puts response.ok?
wait_for_selector
def wait_for_selector(selector, state: nil, strict: nil, timeout: nil)
Returns when element specified by selector satisfies state
option. Returns null
if waiting for hidden
or
detached
.
NOTE: Playwright automatically waits for element to be ready before performing an action. Using Locator objects and web-first assertions makes the code wait-for-selector-free.
Wait for the selector
to satisfy state
option (either appear/disappear from dom, or become
visible/hidden). If at the moment of calling the method selector
already satisfies the condition, the method
will return immediately. If the selector doesn't satisfy the condition for the timeout
milliseconds, the
function will throw.
Usage
This method works across navigations:
%w[https://google.com https://bbc.com].each do |current_url|
page.goto(current_url, waitUntil: "domcontentloaded")
element = page.wait_for_selector("img")
puts "Loaded image: #{element["src"]}"
end
wait_for_timeout
def wait_for_timeout(timeout)
Waits for the given timeout
in milliseconds.
Note that page.waitForTimeout()
should only be used for debugging. Tests using the timer in production are going to be
flaky. Use signals such as network events, selectors becoming visible and others instead.
Usage
page.wait_for_timeout(1000)
wait_for_url
def wait_for_url(url, timeout: nil, waitUntil: nil)
Waits for the main frame to navigate to the given URL.
Usage
page.click("a.delayed-navigation") # clicking the link will indirectly cause a navigation
page.wait_for_url("**/target.html")
expect_websocket
def expect_websocket(predicate: nil, timeout: nil, &block)
Performs action and waits for a new WebSocket. If predicate is provided, it passes
WebSocket value into the predicate
function and waits for predicate(webSocket)
to return a truthy value.
Will throw an error if the page is closed before the WebSocket event is fired.
expect_worker
def expect_worker(predicate: nil, timeout: nil, &block)
Performs action and waits for a new Worker. If predicate is provided, it passes
Worker value into the predicate
function and waits for predicate(worker)
to return a truthy value.
Will throw an error if the page is closed before the worker event is fired.
workers
def workers
This method returns all of the dedicated WebWorkers associated with the page.
NOTE: This does not contain ServiceWorkers
clock
Playwright has ability to mock clock and passage of time.
accessibility
keyboard
mouse
request
API testing helper associated with this page. This method returns the same instance as BrowserContext#request on the page's context. See BrowserContext#request for more details.
