XMLHttpRequest

package js.html

extends XMLHttpRequestEventTargetEventTarget

Available on js

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.
