JSHandle

JSHandle class

Represents a reference to a JavaScript object. Instances can be created using Page.evaluateHandle().

Handles prevent the referenced JavaScript object from being garbage-collected unless the handle is purposely disposed. JSHandles are auto-disposed when their associated frame is navigated away or the parent context gets destroyed.

Handles can be used as arguments for any evaluation function such as Page.$eval(), Page.evaluate(), and Page.evaluateHandle(). They are resolved to their referenced object.

Signature:

export declare class JSHandle<T = unknown>

Remarks

The constructor for this class is marked as internal. Third-party code should not call the constructor directly or create subclasses that extend the JSHandle class.

Example

const windowHandle = await page.evaluateHandle(() => window);
