Note: This feature is available in Web Workers, except for Service Workers.
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.
Exampleconst xhr = new XMLHttpRequest();
xhr.open("GET", "/server", true);
xhr.timeout = 2000; // time in milliseconds
xhr.onload = () => {
// Request finished. Do processing here.
};
xhr.ontimeout = (e) => {
// XMLHttpRequest timed out. Do something here.
};
xhr.send(null);
