}

Parameter | Type | Description |
---|---|---|
prototypeHandle | JSHandle<Prototype> | a handle to the object prototype. |
Returns:
Promise<JSHandle<Prototype[]>>
Promise which resolves to a handle to an array of objects with this prototype.

// Create a Map object
await page.evaluate(() => (window.map = new Map()));
// Get a handle to the Map object prototype
const mapPrototype = await page.evaluateHandle(() => Map.prototype);
// Query all map instances into an array
const mapInstances = await page.queryObjects(mapPrototype);
// Count amount of map objects in heap
const count = await page.evaluate(maps => maps.length, mapInstances);
await mapInstances.dispose();
await mapPrototype.dispose();
