Frame class

Represents a DOM frame.

To understand frames, you can think of frames as <iframe> elements. Just like iframes, frames can be nested, and when JavaScript is executed in a frame, the JavaScript does not effect frames inside the ambient frame the JavaScript executes in.

Signature:

export declare abstract class Frame extends EventEmitter<FrameEvents>

Extends: EventEmitter<FrameEvents>

Remarks

Frame lifecycles are controlled by three events that are all dispatched on the parent page:

The constructor for this class is marked as internal. Third-party code should not call the constructor directly or create subclasses that extend the Frame class.

Example 1

At any point in time, pages expose their current frame tree via the Page.mainFrame() and Frame.childFrames() methods.

Example 2

An example of dumping frame tree:

import puppeteer from 'puppeteer';

(async () => {
const browser = await puppeteer.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 + ' ');
}
}
})();

Example 3

An example of getting text from an iframe element:

const frame = page.frames().find(frame => frame.name() === 'myframe');
const text = await frame.$eval('.selector', element => element.textContent);
console.log(text);

Methods

Method

Description

$(selector)

Queries the frame for an element matching the given selector.

$$(selector)

Queries the frame for all elements matching the given selector.

$$eval(selector, pageFunction, args)

Runs the given function on an array of elements matching the given selector in the frame.

If the given function returns a promise, then this method will wait till the promise resolves.

$eval(selector, pageFunction, args)

Runs the given function on the first element matching the given selector in the frame.

If the given function returns a promise, then this method will wait till the promise resolves.

addScriptTag(options)

Adds a <script> tag into the page with the desired url or content.

addStyleTag(options)

Adds a HTMLStyleElement into the frame with the desired URL

addStyleTag(options)

Adds a HTMLLinkElement into the frame with the desired URL

childFrames()

An array of child frames.

click(selector, options)

Clicks the first element found that matches selector.

Remarks:

If click() triggers a navigation event and there's a separate page.waitForNavigation() promise to be resolved, you may end up with a race condition that yields unexpected results. The correct pattern for click and wait for navigation is the following:

const [response] = await Promise.all([
page.waitForNavigation(waitOptions),
frame.click(selector, clickOptions),
]);
content()

The full HTML contents of the frame, including the DOCTYPE.

evaluate(pageFunction, args)

Behaves identically to Page.evaluate() except it's run within the context of this frame.

evaluateHandle(pageFunction, args)

Behaves identically to Page.evaluateHandle() except it's run within the context of this frame.

focus(selector)

Focuses the first element that matches the selector.

frameElement()
goto(url, options)

Navigates the frame to the given url.

Remarks:

Navigation to about:blank or navigation to the same URL with a different hash will succeed and return null.

warning

Headless mode doesn't support navigation to a PDF document. See the upstream issue.

hover(selector)

Hovers the pointer over the center of the first element that matches the selector.

isDetached()

deprecated

Istrue if the frame has been detached. Otherwise, false.

Deprecated:

Use the detached getter.

isOOPFrame()

Is true if the frame is an out-of-process (OOP) frame. Otherwise, false.

locator(selector)

Creates a locator for the provided selector. See Locator for details and supported actions.

Remarks:

Locators API is experimental and we will not follow semver for breaking change in the Locators API.

locator(func)

Creates a locator for the provided function. See Locator for details and supported actions.

Remarks:

Locators API is experimental and we will not follow semver for breaking change in the Locators API.

name()

deprecated

The frame's name attribute as specified in the tag.

Deprecated:

Use

const element = await frame.frameElement();
const nameOrId = await element.evaluate(frame => frame.name ?? frame.id);

Remarks:

This value is calculated once when the frame is created, and will not update if the attribute is changed later.

page()

The page associated with the frame.

parentFrame()

The parent frame, if any. Detached and main frames return null.

select(selector, values)

Selects a set of value on the first <select> element that matches the selector.

setContent(html, options)

Set the content of the frame.

tap(selector)

Taps the first element that matches the selector.

title()

The frame's title.

type(selector, text, options)

Sends a keydown, keypress/input, and keyup event for each character in the text.

Remarks:

To press a special key, like Control or ArrowDown, use Keyboard.press().

url()

The frame's URL.

waitForFunction(pageFunction, options, args)
waitForNavigation(options)

Waits for the frame to navigate. It is useful for when you run code which will indirectly cause the frame to navigate.

Usage of the History API to change the URL is considered a navigation.

waitForSelector(selector, options)

Waits for an element matching the given selector to appear in the frame.

This method works across navigations.
