The read-only XMLHttpRequest.status
property returns the numerical HTTP status code of the XMLHttpRequest
's response.
Before the request completes, the value of status
is 0. Browsers also report a status of 0 in case of XMLHttpRequest
errors.
Example
var xhr = new XMLHttpRequest(); console.log('UNSENT: ', xhr.status); xhr.open('GET', '/server'); console.log('OPENED: ', xhr.status); xhr.onprogress = function () { console.log('LOADING: ', xhr.status); }; xhr.onload = function () { console.log('DONE: ', xhr.status); }; xhr.send(); /** * Outputs the following: * * UNSENT: 0 * OPENED: 0 * LOADING: 200 * DONE: 200 */
