import { ElementHandle } from "https://deno.land/x/pptr@1.2.0/src/JSHandle.ts";
This method runs document.querySelectorAll within the element and passes it as
the first argument to pageFunction. If there's no element matching selector,
the method throws an error.
If pageFunction returns a Promise, then frame.$$eval would wait for the
promise to resolve and return its value.
Examples
Example 1
Example 1
<div class="feed">
<div class="tweet">Hello!</div>
<div class="tweet">Hi!</div>
</div>
Example 2
Example 2
const feedHandle = await page.$('.feed');
expect(await feedHandle.$$eval('.tweet', nodes => nodes.map(n => n.innerText)))
.toEqual(['Hello!', 'Hi!']);
Parameters
pageFunction: (elements: Element[], ...args: unknown[]) => ReturnType | Promise<ReturnType>
...args: SerializableOrJSHandle[]
Returns
Promise<WrapElementHandle<ReturnType>>
