## ElementHandle.$$eval() method

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.

<b>Signature:</b>

```typescript
$$eval<ReturnType extends any>(selector: string, pageFunction: Function | string, ...args: unknown[]): Promise<ReturnType>;
```

## Parameters

|  Parameter | Type | Description |
|  --- | --- | --- |
|  selector | string |  |
|  pageFunction | Function \| string |  |
|  args | unknown\[\] |  |

<b>Returns:</b>

Promise&lt;ReturnType&gt;

<div class="feed">
  <div class="tweet">Hello!</div>
  <div class="tweet">Hi!</div>

```

const feedHandle = await page.$('.feed');
expect(await feedHandle.$$eval('.tweet', nodes => nodes.map(n => n.innerText)))
