The XMLHttpRequest.timeout
property is an unsigned long
representing the number of milliseconds a request can take before automatically being terminated. The default value is 0, which means there is no timeout. Timeout shouldn't be used for synchronous XMLHttpRequests requests used in a document environment or it will throw an InvalidAccessError
exception. When a timeout happens, a timeout event is fired.
-
Note: You may not use a timeout for synchronous requests with an owning window.
- Using a timeout with an asynchronous request
In Internet Explorer, the timeout property may be set only after calling the open() method and before calling the send() method.
Example
var xhr = new XMLHttpRequest(); xhr.open('GET', '/server', true); xhr.timeout = 2000; // time in milliseconds xhr.onload = function () { // Request finished. Do processing here. }; xhr.ontimeout = function (e) { // XMLHttpRequest timed out. Do something here. }; xhr.send(null);
