## 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>(selector: string, pageFunction: (elements: Element[], ...args: unknown[]) => ReturnType | Promise<ReturnType>, ...args: SerializableOrJSHandle[]): Promise<WrapElementHandle<ReturnType>>;
```

|  args | [SerializableOrJSHandle](./puppeteer.serializableorjshandle.md)<!-- -->\[\] |  |

<b>Returns:</b>

Promise&lt;[WrapElementHandle](./puppeteer.wrapelementhandle.md)<!-- -->&lt;ReturnType&gt;&gt;
