# ExecutionContext.evaluate() method
|
||||
|
||||
Evaluates the given function.
|
||||
|
||||
**Signature:**
|
||||
|
||||
```typescript
|
||||
class ExecutionContext {
|
||||
evaluate<
|
||||
Params extends unknown[],
|
||||
Func extends EvaluateFunc<Params> = EvaluateFunc<Params>
|
||||
>(
|
||||
pageFunction: Func | string,
|
||||
...args: Params
|
||||
): Promise<Awaited<ReturnType<Func>>>;
|
||||
}
|
||||
```
|
||||
|
||||
## Parameters
|
||||
|
||||
| Parameter | Type | Description |
|
||||
| ------------ | -------------- | ----------------------------------------------- |
|
||||
| pageFunction | Func \| string | The function to evaluate. |
|
||||
| args | Params | Additional arguments to pass into the function. |
|
||||
|
||||
**Returns:**
|
||||
|
||||
Promise<Awaited<ReturnType<Func>>>
|
||||
|
||||
The result of evaluating the function. If the result is an object, a vanilla object containing the serializable properties of the result is returned.
|
||||
|
||||
## Example 1
|
||||
|
||||
```ts
|
||||
const executionContext = await page.mainFrame().executionContext();
|
||||
const result = await executionContext.evaluate(() => Promise.resolve(8 * 7))* ;
|
||||
console.log(result); // prints "56"
|
||||
```
|
||||
|
||||
## Example 2
|
||||
|
||||
A string can also be passed in instead of a function:
|
||||
|
||||
```ts
|
||||
console.log(await executionContext.evaluate('1 + 2')); // prints "3"
|
||||
```
|
||||
|
||||
## Example 3
|
||||
|
||||
Handles can also be passed as `args`. They resolve to their referenced object:
|
||||
|
||||
```ts
|
||||
const oneHandle = await executionContext.evaluateHandle(() => 1);
|
||||
const twoHandle = await executionContext.evaluateHandle(() => 2);
|
||||
const result = await executionContext.evaluate(
|
||||
(a, b) => a + b,
|
||||
oneHandle,
|
||||
twoHandle
|
||||
);
|
||||
await oneHandle.dispose();
|
||||
await twoHandle.dispose();
|
||||
console.log(result); // prints '3'.
|
||||
```

# ExecutionContext.evaluateHandle() method
|
||||
|
||||
Evaluates the given function.
|
||||
|
||||
Unlike [evaluate](./puppeteer.executioncontext.evaluate.md), this method returns a handle to the result of the function.
|
||||
|
||||
This method may be better suited if the object cannot be serialized (e.g. `Map`) and requires further manipulation.
|
||||
|
||||
**Signature:**
|
||||
|
||||
```typescript
|
||||
class ExecutionContext {
|
||||
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 | The function to evaluate. |
|
||||
| args | Params | Additional arguments to pass into the function. |
|
||||
|
||||
**Returns:**
|
||||
|
||||
Promise<[HandleFor](./puppeteer.handlefor.md)<Awaited<ReturnType<Func>>>>
|
||||
|
||||
A [handle](./puppeteer.jshandle.md) to the result of evaluating the function. If the result is a `Node`, then this will return an [element handle](./puppeteer.elementhandle.md).
|
||||
|
||||
## Example 1
|
||||
|
||||
```ts
|
||||
const context = await page.mainFrame().executionContext();
|
||||
const handle: JSHandle<typeof globalThis> = await context.evaluateHandle(() =>
|
||||
Promise.resolve(self)
|
||||
);
|
||||
```
|
||||
|
||||
## Example 2
|
||||
|
||||
A string can also be passed in instead of a function.
|
||||
|
||||
```ts
|
||||
const handle: JSHandle<number> = await context.evaluateHandle('1 + 2');
|
||||
```
|
||||
|
||||
## Example 3
|
||||
|
||||
Handles can also be passed as `args`. They resolve to their referenced object:
|
||||
|
||||
```ts
|
||||
const bodyHandle: ElementHandle<HTMLBodyElement> = await context.evaluateHandle(
|
||||
() => {
|
||||
return document.body;
|
||||
}
|
||||
);
|
||||
const stringHandle: JSHandle<string> = await context.evaluateHandle(
|
||||
body => body.innerHTML,
|
||||
body
|
||||
);
|
||||
console.log(await stringHandle.jsonValue()); // prints body's innerHTML
|
||||
// Always dispose your garbage! :)
|
||||
await bodyHandle.dispose();
|
||||
await stringHandle.dispose();

|
||||
|
||||

# ExecutionContext class
|
||||
|
||||
> Warning: This API is now obsolete.
|
||||
>
|
||||
> Do not use directly.
|
||||
>
|
||||
> Represents a context for JavaScript execution.

|
||||
**Signature:**
|
||||
|
||||
```typescript
|
||||
export declare class ExecutionContext
|
||||
```
|
||||
|
||||
## Remarks
|
||||
|
||||
Besides pages, execution contexts can be found in [workers](./puppeteer.webworker.md).
|
||||
|
||||
The constructor for this class is marked as internal. Third-party code should not call the constructor directly or create subclasses that extend the `ExecutionContext` class.
|
||||
|
||||
## Example
|
||||
|
||||
A [Page](./puppeteer.page.md) can have several execution contexts:
|
||||
|
||||
- Each [Frame](./puppeteer.frame.md) of a [page](./puppeteer.page.md) has a "default" execution context that is always created after frame is attached to DOM. This context is returned by the [Frame.executionContext()](./puppeteer.frame.executioncontext.md) method. - Each [Chrome extensions](https://developer.chrome.com/extensions) creates additional execution contexts to isolate their code.

|
||||
| [Accessibility](./puppeteer.accessibility.md) | The Accessibility class provides methods for inspecting Chromium's accessibility tree. The accessibility tree is used by assistive technology such as [screen readers](https://en.wikipedia.org/wiki/Screen_reader) or [switches](https://en.wikipedia.org/wiki/Switch_access). |
|
||||
| [Browser](./puppeteer.browser.md) | A Browser is created when Puppeteer connects to a Chromium instance, either through [PuppeteerNode.launch()](./puppeteer.puppeteernode.launch.md) or [Puppeteer.connect()](./puppeteer.puppeteer.connect.md). |
|
||||
| [BrowserContext](./puppeteer.browsercontext.md) | BrowserContexts provide a way to operate multiple independent browser sessions. When a browser is launched, it has a single BrowserContext used by default. The method [Browser.newPage](./puppeteer.browser.newpage.md) creates a page in the default browser context. |
|
||||
| [BrowserFetcher](./puppeteer.browserfetcher.md) | BrowserFetcher can download and manage different versions of Chromium and Firefox. |
|
||||
| [CDPSession](./puppeteer.cdpsession.md) | The <code>CDPSession</code> instances are used to talk raw Chrome Devtools Protocol. |
|
||||
| [Connection](./puppeteer.connection.md) | |
|
||||
| [ConsoleMessage](./puppeteer.consolemessage.md) | ConsoleMessage objects are dispatched by page via the 'console' event. |
|
||||
| [Coverage](./puppeteer.coverage.md) | The Coverage class provides methods to gathers information about parts of JavaScript and CSS that were used by the page. |
|
||||
| [CSSCoverage](./puppeteer.csscoverage.md) | |
|
||||
| [CustomError](./puppeteer.customerror.md) | |
|
||||
| [Dialog](./puppeteer.dialog.md) | Dialog instances are dispatched by the [Page](./puppeteer.page.md) via the <code>dialog</code> event. |
|
||||
| [ElementHandle](./puppeteer.elementhandle.md) | ElementHandle represents an in-page DOM element. |
|
||||
| [EventEmitter](./puppeteer.eventemitter.md) | The EventEmitter class that many Puppeteer classes extend. |
|
||||
| [ExecutionContext](./puppeteer.executioncontext.md) | |
|
||||
| [FileChooser](./puppeteer.filechooser.md) | File choosers let you react to the page requesting for a file. |
|
||||
| [Frame](./puppeteer.frame.md) | <p>Represents a DOM frame.</p><p>To understand frames, you can think of frames as <code><iframe></code> elements. Just like iframes, frames can be nested, and when JavaScript is executed in a frame, the JavaScript does not effect frames inside the ambient frame the JavaScript executes in.</p> |
|
||||
| [HTTPRequest](./puppeteer.httprequest.md) | Represents an HTTP request sent by a page. |
|
||||
| [HTTPResponse](./puppeteer.httpresponse.md) | The HTTPResponse class represents responses which are received by the [Page](./puppeteer.page.md) class. |
|
||||
| [JSCoverage](./puppeteer.jscoverage.md) | |
|
||||
| [JSHandle](./puppeteer.jshandle.md) | <p>Represents a reference to a JavaScript object. Instances can be created using [Page.evaluateHandle()](./puppeteer.page.evaluatehandle.md).</p><p>Handles prevent the referenced JavaScript object from being garbage-collected unless the handle is purposely [disposed](./puppeteer.jshandle.dispose.md). JSHandles are auto-disposed when their associated frame is navigated away or the parent context gets destroyed.</p><p>Handles can be used as arguments for any evaluation function such as [Page.$eval()](./puppeteer.page._eval.md), [Page.evaluate()](./puppeteer.page.evaluate.md), and [Page.evaluateHandle()](./puppeteer.page.evaluatehandle.md). They are resolved to their referenced object.</p> |
|
||||
| [Keyboard](./puppeteer.keyboard.md) | Keyboard provides an api for managing a virtual keyboard. The high level api is [Keyboard.type()](./puppeteer.keyboard.type.md), which takes raw characters and generates proper keydown, keypress/input, and keyup events on your page. |
|
||||
| [Mouse](./puppeteer.mouse.md) | The Mouse class operates in main-frame CSS pixels relative to the top-left corner of the viewport. |

| [Browser](./puppeteer.browser.md) | A Browser is created when Puppeteer connects to a Chromium instance, either through [PuppeteerNode.launch()](./puppeteer.puppeteernode.launch.md) or [Puppeteer.connect()](./puppeteer.puppeteer.connect.md). |
|
||||
| [BrowserContext](./puppeteer.browsercontext.md) | BrowserContexts provide a way to operate multiple independent browser sessions. When a browser is launched, it has a single BrowserContext used by default. The method [Browser.newPage](./puppeteer.browser.newpage.md) creates a page in the default browser context. |
|
||||
| [BrowserFetcher](./puppeteer.browserfetcher.md) | BrowserFetcher can download and manage different versions of Chromium and Firefox. |
