## Page.evaluateHandle() method

<b>Signature:</b>

```typescript
evaluateHandle<HandlerType extends JSHandle = JSHandle>(pageFunction: EvaluateHandleFn, ...args: SerializableOrJSHandle[]): Promise<HandlerType>;
```

## Parameters

|  Parameter | Type | Description |
|  --- | --- | --- |
|  pageFunction | [EvaluateHandleFn](./puppeteer.evaluatehandlefn.md) | a function that is run within the page |
|  args | [SerializableOrJSHandle](./puppeteer.serializableorjshandle.md)<!-- -->\[\] | arguments to be passed to the pageFunction |

<b>Returns:</b>

Promise&lt;HandlerType&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


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

```

## Example 2

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

```
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


```
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:

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

```
