The XMLHttpRequest.abort()
method aborts the request if it has already been sent. When a request is aborted, its readyState
is changed to XMLHttpRequest.UNSENT
(0) and the request's status
code is set to 0.
If the request is still in progress (its readyState
is not XMLHttpRequest.DONE
or XMLHttpRequest.UNSENT
), a readystatechange
event, abort
, and a loadend
event are dispatched, in that order. For synchronous requests, no events are dispatched and an error is thrown instead.
None.
Return valueNone (undefined
).
This example begins loading content from the MDN home page, then due to some condition, aborts the transfer by calling abort()
.
const xhr = new XMLHttpRequest();
const method = "GET";
const url = "https://developer.mozilla.org/";
xhr.open(method, url, true);
xhr.send();
if (OH_NOES_WE_NEED_TO_CANCEL_RIGHT_NOW_OR_ELSE) {
xhr.abort();
}
