How to view the last GET HTTP request in JavaScript

By | January 12, 2018

How can I view the last GET http request in JavaScript? Basically what I am after is what I can see my firebug console. When XMLHttpRequests are showing in console I see a line that looks something like:

GET   200   OK   163ms

How do I view that URL in JavaScript?

EDIT: Just to be clear I’m looking for the URL between GET… and …200. I don’t care about anything else. I don’t want any of the other info.


You may want to modify the to decorate it with your “tracking” code. Something like this:

var ajaxCalls = [];

XMLHttpRequest.prototype._originalOpen =; = function(method, url, async, user, password) {
   this._originalOpen(method, url, async, user, password);

The ajaxCalls array will get populated with the URLs of your Ajax requests. The last request will be at ajaxCalls[ajaxCalls.length - 1].

Note that if you want to track only GET requests, you can simply log URLs only if method === 'GET' in the open() method.


Daniel’s solution works, but not for IE8 and lower, as IE has different number of arguments.

Try this instead:

window.XMLHttpRequest.prototype._original_open =; = function() {


I ended up going with a workaround using $_SERVER['REQUEST_URI'] in PHP and then passing it to JavaScript.
