Overview
At every point of time, page exposes its current frame tree via the [‘method: Page.mainFrame`] and
- ‘method: Frame.childFrames`
-
methods.
‘Frame` object’s lifecycle is controlled by three events, dispatched on the page object:
- ‘event: Page.frameattached`
-
fired when the frame gets attached to the page. A Frame can be attached to the page
-
only once.
- ‘event: Page.framenavigated`
-
fired when the frame commits navigation to a different URL.
-
- ‘event: Page.framedetached`
-
fired when the frame gets detached from the page. A Frame can be detached from the
-
page only once.
An example of dumping frame tree:
“‘js const { firefox } = require(’playwright’); // Or ‘chromium’ or ‘webkit’.
(async () => {
const browser = await firefox.launch();
const page = await browser.newPage();
await page.goto('https://www.google.com/chrome/browser/canary.html');
dumpFrameTree(page.mainFrame(), '');
await browser.close();
function dumpFrameTree(frame, indent) {
console.log(indent + frame.url());
for (const child of frame.childFrames()) {
dumpFrameTree(child, indent + ' ');
}
}
})(); “‘
“‘python async import asyncio from playwright.async_api import async_playwright
async def run(playwright):
firefox = playwright.firefox
browser = await firefox.launch()
page = await browser.new_page()
await page.goto("https://www.theverge.com")
dump_frame_tree(page.main_frame, "")
await browser.close()
def dump_frame_tree(frame, indent):
print(indent + frame.name + '@' + frame.url)
for child in frame.child_frames:
dump_frame_tree(child, indent + " ")
async def main():
async with async_playwright() as playwright:
await run(playwright)
asyncio.run(main()) “‘
“‘python sync from playwright.sync_api import sync_playwright

#check(selector, force: nil, noWaitAfter: nil, timeout: nil) ⇒ Object
This method checks an element matching ‘selector` by performing the following steps:
-
Find an element match 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 rejects. If the element is already checked, this method returns immediately.
-
Wait for [actionability](./actionability.md) 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 [‘property: Page.mouse`] to click in the center of the element.
-
Wait for initiated navigations to either succeed or fail, unless ‘noWaitAfter` option is set.
-
Ensure that the element is now checked. If not, this method rejects.
When all steps combined have not finished during the specified ‘timeout`, this method rejects with a `TimeoutError`. Passing zero timeout disables this.

#dblclick(selector, button: nil, delay: nil, force: nil, modifiers: nil, noWaitAfter: nil, position: nil, timeout: nil) ⇒ Object
This method double clicks an element matching ‘selector` by performing the following steps:
-
Find an element match matching ‘selector`. If there is none, wait until a matching element is attached to the DOM.
-
Wait for [actionability](./actionability.md) 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 [‘property: Page.mouse`] to double 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. Note that if the first click of the `dblclick()` triggers a navigation event, this method will reject.
When all steps combined have not finished during the specified ‘timeout`, this method rejects with a `TimeoutError`. Passing zero timeout disables this.
> NOTE: ‘frame.dblclick()` dispatches two `click` events and a single `dblclick` event.

#dispatch_event(selector, type, eventInit: nil, timeout: nil) ⇒ Object
The snippet below dispatches the ‘click` event on the element. Regardless of the visibility state of the elment, `click` is dispatched. This is equivalend to calling [element.click()](developer.mozilla.org/en-US/docs/Web/API/HTMLElement/click).
“‘js await frame.dispatchEvent(’button#submit’, ‘click’); “‘
“‘python async await frame.dispatch_event(“button#submit”, “click”) “`
“‘python sync frame.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:
-
[DragEvent](developer.mozilla.org/en-US/docs/Web/API/DragEvent/DragEvent)
-
[FocusEvent](developer.mozilla.org/en-US/docs/Web/API/FocusEvent/FocusEvent)

You can also specify ‘JSHandle` as the property value if you want live objects to be passed into the event:
“‘js // Note you can only create DataTransfer in Chromium and Firefox const dataTransfer = await frame.evaluateHandle(() => new DataTransfer()); await frame.dispatchEvent(’#source’, ‘dragstart’, { dataTransfer }); “‘
“‘python async # note you can only create data_transfer in chromium and firefox data_transfer = await frame.evaluate_handle(“new DataTransfer()”) await frame.dispatch_event(“#source”, “dragstart”, { “dataTransfer”: data_transfer }) “`
“‘python sync # note you can only create data_transfer in chromium and firefox data_transfer = frame.evaluate_handle(“new DataTransfer()”) frame.dispatch_event(“#source”, “dragstart”, { “dataTransfer”: data_transfer }) “`

#eval_on_selector(selector, pageFunction, arg: nil) ⇒ Object
Returns the return value of ‘pageFunction`
The method finds an element matching the specified selector within the frame and passes it as a first argument to ‘pageFunction`. See [Working with selectors](./selectors.md#working-with-selectors) for more details. If no elements match the selector, the method throws an error.
If ‘pageFunction` returns a [Promise], then `frame.$eval` would wait for the promise to resolve and return its value.
Examples:
“‘js const searchValue = await frame.$eval(’#search’, el => el.value); const preloadHref = await frame.$eval(‘link’, el => el.href); const html = await frame.$eval(‘.main-container’, (e, suffix) => e.outerHTML + suffix, ‘hello’); “‘
“‘python async search_value = await frame.eval_on_selector(“#search”, “el => el.value”) preload_href = await frame.eval_on_selector(“link”, “el => el.href”) html = await frame.eval_on_selector(“.main-container”, “(e, suffix) => e.outerHTML + suffix”, “hello”) “`
“‘python sync search_value = frame.eval_on_selector(“#search”, “el => el.value”) preload_href = frame.eval_on_selector(“link”, “el => el.href”) html = frame.eval_on_selector(“.main-container”, “(e, suffix) => e.outerHTML + suffix”, “hello”) “`

#eval_on_selector_all(selector, pageFunction, arg: nil) ⇒ Object
Returns the return value of ‘pageFunction`
The method finds all elements matching the specified selector within the frame and passes an array of matched elements as a first argument to ‘pageFunction`. See [Working with selectors](./selectors.md#working-with-selectors) for more details.
If ‘pageFunction` returns a [Promise], then `frame.$$eval` would wait for the promise to resolve and return its value.
Examples:
“‘js const divsCounts = await frame.$$eval(’div’, (divs, min) => divs.length >= min, 10); “‘
“‘python async divs_counts = await frame.eval_on_selector_all(“div”, “(divs, min) => divs.length >= min”, 10) “`
“‘python sync divs_counts = frame.eval_on_selector_all(“div”, “(divs, min) => divs.length >= min”, 10) “`

#evaluate(pageFunction, arg: nil) ⇒ Object
Returns the return value of ‘pageFunction`
If the function passed to the [‘method: Frame.evaluate`] returns a [Promise], then [`method: Frame.evaluate`] would wait for the promise to resolve and return its value.
If the function passed to the [‘method: Frame.evaluate`] returns a non- value, then[ method: `Frame.evaluate`] returns `undefined`. DevTools Protocol also supports transferring some additional values that are not serializable by `JSON`: `-0`, `NaN`, `Infinity`, `-Infinity`, and bigint literals.
“‘js const result = await frame.evaluate(([x, y]) =>
return Promise.resolve(x * y);
, [7, 8]); console.log(result); // prints “56” “‘
“‘python async result = await frame.evaluate(“([x, y]) => Promise.resolve(x * y)”, [7, 8]) print(result) # prints “56” “`
“‘python sync result = frame.evaluate(“([x, y]) => Promise.resolve(x * y)”, [7, 8]) print(result) # prints “56” “`
A string can also be passed in instead of a function.
“‘js console.log(await frame.evaluate(’1 + 2’)); // prints “3” “‘
“‘python async print(await frame.evaluate(“1 + 2”)) # prints “3” x = 10 print(await frame.evaluate(f“1 + x”)) # prints “11” “`
“‘python sync print(frame.evaluate(“1 + 2”)) # prints “3” x = 10 print(frame.evaluate(f“1 + x”)) # prints “11” “`
‘ElementHandle` instances can be passed as an argument to the [`method: Frame.evaluate`]:
“‘js const bodyHandle = await frame.$(’body’); const html = await frame.evaluate(([body, suffix]) => body.innerHTML + suffix, [bodyHandle, ‘hello’]); await bodyHandle.dispose(); “‘
“‘python async body_handle = await frame.query_selector(“body”) html = await frame.evaluate(“([body, suffix]) => body.innerHTML + suffix”, [body_handle, “hello”]) await body_handle.dispose() “`
“‘python sync body_handle = frame.query_selector(“body”) html = frame.evaluate(“([body, suffix]) => body.innerHTML + suffix”, [body_handle, “hello”]) body_handle.dispose() “`

# File 'lib/playwright_api/frame.rb', line 362 def evaluate(pageFunction, arg: nil) wrap_impl(@impl.evaluate(pageFunction, arg: arg)) end |
#evaluate_handle(pageFunction, arg: nil) ⇒ Object
Returns the return value of ‘pageFunction` as in-page object (JSHandle).
The only difference between [‘method: Frame.evaluate`] and [`method: Frame.evaluateHandle`] is that[ method: Fframe.evaluateHandle`] returns in-page object (JSHandle).
If the function, passed to the [‘method: Frame.evaluateHandle`], returns a [Promise], then[ method: Fframe.evaluateHandle`] would wait for the promise to resolve and return its value.
“‘js const aWindowHandle = await frame.evaluateHandle(() => Promise.resolve(window)); aWindowHandle; // Handle for the window object. “`
“‘python async # FIXME a_window_handle = await frame.evaluate_handle(“Promise.resolve(window)”) a_window_handle # handle for the window object. “`
“‘python sync a_window_handle = frame.evaluate_handle(“Promise.resolve(window)”) a_window_handle # handle for the window object. “`
A string can also be passed in instead of a function.
“‘js const aHandle = await frame.evaluateHandle(’document’); // Handle for the ‘document’. “‘
“‘python async a_handle = await page.evaluate_handle(“document”) # handle for the “document” “`
“‘python sync a_handle = page.evaluate_handle(“document”) # handle for the “document” “`
‘JSHandle` instances can be passed as an argument to the [`method: Frame.evaluateHandle`]:
“‘js const aHandle = await frame.evaluateHandle(() => document.body); const resultHandle = await frame.evaluateHandle(([body, suffix]) => body.innerHTML + suffix, [aHandle, ’hello’]); console.log(await resultHandle.jsonValue()); await resultHandle.dispose(); “‘
“‘python async a_handle = await page.evaluate_handle(“document.body”) result_handle = await page.evaluate_handle(“body => body.innerHTML”, a_handle) print(await result_handle.json_value()) await result_handle.dispose() “`
“‘python sync a_handle = page.evaluate_handle(“document.body”) result_handle = page.evaluate_handle(“body => body.innerHTML”, a_handle) print(result_handle.json_value()) result_handle.dispose() “`

#expect_navigation(timeout: nil, url: nil, waitUntil: nil) ⇒ Object
Waits for the 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`.
This method waits for the frame to navigate to a new URL. It is useful for when you run code which will indirectly cause the frame to navigate. Consider this example:
“‘js const [response] = await Promise.all([
frame.waitForNavigation(), // The promise resolves after navigation has finished
frame.click('a.delayed-navigation'), // Clicking the link will indirectly cause a navigation
]); “‘
“‘python async async with frame.expect_navigation():
await frame.click("a.delayed-navigation") # clicking the link will indirectly cause a navigation
# Resolves after navigation has finished “‘
“‘python sync with frame.expect_navigation():
frame.click("a.delayed-navigation") # clicking the link will indirectly cause a navigation
# Resolves after navigation has finished “‘
> NOTE: Usage of the [History API](developer.mozilla.org/en-US/docs/Web/API/History_API) to change the URL is considered a navigation.

#fill(selector, value, noWaitAfter: nil, timeout: nil) ⇒ Object
This method waits for an element matching ‘selector`, waits for [actionability](./actionability.md) checks, focuses the element, fills it and triggers an `input` event after filling. If the element matching `selector` is not an `<input>`, `<textarea>` or `[contenteditable]` element, this method throws an error. Note that you can pass an empty string to clear the input field.
To send fine-grained keyboard events, use [‘method: Frame.type`].

#focus(selector, timeout: nil) ⇒ Object
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_element ⇒ Object
Returns the ‘frame` or `iframe` element handle which corresponds to this frame.
This is an inverse of [‘method: ElementHandle.contentFrame`]. Note that returned handle actually belongs to the parent frame.
This method throws an error if the frame has been detached before ‘frameElement()` returns.
“‘js const frameElement = await frame.frameElement(); const contentFrame = await frameElement.contentFrame(); console.log(frame === contentFrame); // -> true “`
“‘python async frame_element = await frame.frame_element() content_frame = await frame_element.content_frame() assert frame == content_frame “`

#goto(url, referer: nil, timeout: nil, waitUntil: nil) ⇒ Object
Returns the main resource response. In case of multiple redirects, the navigation will resolve with the response of the last redirect.
‘frame.goto` 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.
‘frame.goto` 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 [`method: Response.status`].
> NOTE: ‘frame.goto` 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](bugs.chromium.org/p/chromium/issues/detail?id=761295).

#hover(selector, force: nil, modifiers: nil, position: nil, timeout: nil) ⇒ Object
This method hovers over an element matching ‘selector` by performing the following steps:
-
Find an element match matching ‘selector`. If there is none, wait until a matching element is attached to the DOM.
-
Wait for [actionability](./actionability.md) 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 [‘property: Page.mouse`] to hover over 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 rejects with a `TimeoutError`. Passing zero timeout disables this.

#press(selector, key, delay: nil, noWaitAfter: nil, timeout: nil) ⇒ Object
‘key` can specify the intended [keyboardEvent.key](developer.mozilla.org/en-US/docs/Web/API/KeyboardEvent/key) value or a single character to generate the text for. A superset of the `key` values can be found [here](developer.mozilla.org/en-US/docs/Web/API/KeyboardEvent/key/Key_Values). 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`.
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”` or `key: “Control+Shift+T”` are supported as well. When speficied with the modifier, modifier is pressed and being held while the subsequent key is being pressed.

#select_option(selector, values, noWaitAfter: nil, timeout: nil) ⇒ Object
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. If there’s no ‘<select>` element matching `selector`, the method throws an error.
Will wait until all specified options are present in the ‘<select>` element.
“‘js // single selection matching the value frame.selectOption(’select#colors’, ‘blue’);

This method expects ‘selector` to point to an [input element](developer.mozilla.org/en-US/docs/Web/HTML/Element/input).
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 the current working directory. For empty array, clears the selected files.

#tap_point(selector, force: nil, modifiers: nil, noWaitAfter: nil, position: nil, timeout: nil) ⇒ Object
This method taps an element matching ‘selector` by performing the following steps:
-
Find an element match matching ‘selector`. If there is none, wait until a matching element is attached to the DOM.
-
Wait for [actionability](./actionability.md) 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 [‘property: Page.touchscreen`] to tap 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 rejects with a `TimeoutError`. Passing zero timeout disables this.
> NOTE: ‘frame.tap()` requires that the `hasTouch` option of the browser context be set to true.

#type_text(selector, text, delay: nil, noWaitAfter: nil, timeout: nil) ⇒ Object
Sends a ‘keydown`, `keypress`/`input`, and `keyup` event for each character in the text. `frame.type` can be used to send fine-grained keyboard events. To fill values in form fields, use [`method: Frame.fill`].
To press a special key, like ‘Control` or `ArrowDown`, use [`method: Keyboard.press`].

#uncheck(selector, force: nil, noWaitAfter: nil, timeout: nil) ⇒ Object
This method checks an element matching ‘selector` by performing the following steps:
-
Find an element match 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 rejects. If the element is already unchecked, this method returns immediately.
-
Wait for [actionability](./actionability.md) 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 [‘property: Page.mouse`] to click in the center of the element.
-
Wait for initiated navigations to either succeed or fail, unless ‘noWaitAfter` option is set.
-
Ensure that the element is now unchecked. If not, this method rejects.
When all steps combined have not finished during the specified ‘timeout`, this method rejects with a `TimeoutError`. Passing zero timeout disables this.

#wait_for_load_state(state: nil, timeout: nil) ⇒ Object
Waits for the required load state to be reached.
This returns when the frame 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.

#wait_for_selector(selector, state: nil, timeout: nil) ⇒ Object
Returns when element specified by selector satisfies ‘state` option. Returns `null` if waiting for `hidden` or `detached`.
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.
