# Page.evaluateHandle() method

**Signature:**

```typescript
class Page {evaluateHandle<Params extends unknown[], Func extends EvaluateFunc<Params> = EvaluateFunc<Params>>(pageFunction: Func | string, ...args: Params): Promise<HandleFor<Awaited<ReturnType<Func>>>>;}
```

## Parameters

|  Parameter | Type | Description |
|  --- | --- | --- |
|  pageFunction | Func \| string | a function that is run within the page |
|  args | Params | arguments to be passed to the pageFunction |

**Returns:**

Promise&lt;[HandleFor](./puppeteer.handlefor.md)&lt;Awaited&lt;ReturnType&lt;Func&gt;&gt;&gt;&gt;

## Remarks

The only difference between [page.evaluate](./puppeteer.page.evaluate.md) and `page.evaluateHandle` is that `evaluateHandle` will return the value wrapped in an in-page object.

If the function passed to `page.evaluteHandle` returns a Promise, the function will wait for the promise to resolve and return its value.

You can pass a string instead of a function (although functions are recommended as they are easier to debug and use with TypeScript):

## Example 1


```ts
const aHandle = await page.evaluateHandle('document')
```

## Example 2

[JSHandle](./puppeteer.jshandle.md) instances can be passed as arguments to the `pageFunction`:

```ts
const aHandle = await page.evaluateHandle(() => document.body);
const resultHandle = await page.evaluateHandle(body => body.innerHTML, aHandle);
console.log(await resultHandle.jsonValue());
await resultHandle.dispose();
```
Most of the time this function returns a [JSHandle](./puppeteer.jshandle.md), but if `pageFunction` returns a reference to an element, you instead get an [ElementHandle](./puppeteer.elementhandle.md) back:

## Example 3


```ts
const button = await page.evaluateHandle(() => document.querySelector('button'));
// can call `click` because `button` is an `ElementHandle`
await button.click();
```
The TypeScript definitions assume that `evaluateHandle` returns a `JSHandle`, but if you know it's going to return an `ElementHandle`, pass it as the generic argument:

```ts
const button = await page.evaluateHandle<ElementHandle>(...);
```
