/**

* 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.
|
|
*
|
|
* @example
|
|
* At any point in time, {@link Page | pages} expose their current frame
|
|
* tree via the {@link Page.mainFrame} and {@link Frame.childFrames} methods.
|
|
*
|
|
* @example
|
|
* An example of dumping frame tree:
|
|
*
|
|
* ```ts
|
|
* 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
|
|
* An example of getting text from an iframe element:
|
|
*
|
|
* ```ts
|
|
* const frame = page.frames().find(frame => frame.name() === 'myframe');
|
|
* const text = await frame.$eval('.selector', element => element.textContent);
|
|
* console.log(text);
|
|
* ```
|
|
*
|
|
* @remarks
|
|
* Frame lifecycles are controlled by three events that are all dispatched on
|
|
* the parent {@link Frame.page | page}:
|
|
*
|
|
* - {@link PageEmittedEvents.FrameAttached}
|
|
* - {@link PageEmittedEvents.FrameNavigated}
|
