URLSearchParamsIterator

VTTCue

WorkerGlobalScope

The WorkerGlobalScope interface of the Web Workers API is an interface representing the scope of any worker. Workers have no browsing context; this scope contains the information usually conveyed by Window objects — in this case event handlers, the console or the associated WorkerNavigator object. Each WorkerGlobalScope has its own event loop.

WorkerLocation

The WorkerLocation interface defines the absolute location of the script executed by the Worker. Such an object is initialized for each worker and is available via the WorkerGlobalScope.location property obtained by calling self.location.

WorkerNavigator

The WorkerNavigator interface represents a subset of the Navigator interface allowed to be accessed from a Worker. Such an object is initialized for each worker and is available via the WorkerGlobalScope.navigator property obtained by calling window.self.navigator.

XMLHttpRequest

Use XMLHttpRequest (XHR) objects to interact with servers. You can retrieve data from a URL without having to do a full page refresh. This enables a Web page to update just part of a page without disrupting what the user is doing.

XMLHttpRequestEventTarget

XMLHttpRequestResponseType

The XMLHttpRequestResponseType type is an enumerated set of strings which are used to specify the type of data contained in the response of an XMLHttpRequest.

XMLHttpRequestUpload

XPathExpression

An XPathExpression is a compiled XPath query returned from document.createExpression(). It has a method evaluate() which can be used to execute the compiled XPath.

XPathNSResolver

XPathResult
