# Frame.$$eval() method

**Signature:**

```typescript
class Frame {$$eval<Selector extends keyof HTMLElementTagNameMap, Params extends unknown[], Func extends EvaluateFunc<[
        HTMLElementTagNameMap[Selector][],
        ...Params
    ]> = EvaluateFunc<[HTMLElementTagNameMap[Selector][], ...Params]>>(selector: Selector, pageFunction: Func | string, ...args: Params): Promise<Awaited<ReturnType<Func>>>;}
```

## Parameters

|  Parameter | Type | Description |
|  --- | --- | --- |
|  selector | Selector | the selector to query for |
|  pageFunction | Func \| string | the function to be evaluated in the frame's context |
|  args | Params | additional arguments to pass to <code>pageFunction</code> |

**Returns:**

Promise&lt;Awaited&lt;ReturnType&lt;Func&gt;&gt;&gt;

## Remarks

This method runs `Array.from(document.querySelectorAll(selector))` within the frame and passes it as the first argument to `pageFunction`.

If `pageFunction` returns a Promise, then `frame.$$eval` would wait for the promise to resolve and return its value.

## Example


```ts
const divsCounts = await frame.$$eval('div', divs => divs.length);
```
