# 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 `document.querySelector` 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 searchValue = await frame.$eval('#search', el => el.value);
```
