I have a userscript that I need to run EVERY time ANY page to which the userscript is attached is modified by AJAX. Is there any method to listen the XMLHttpRequest-s?

    Are you using jQuery for your Ajax requests? You could use the http://api.jquery.com/ajaxcomplete/ method. – Andy Oct 30 '14 at 10:44
  • @Andy I want to listen all Ajax request, not only mine. It's an userscript which should run on all pages in the web. – MPMOZ Oct 30 '14 at 10:53

I cannot tell exactly what you are looking for without the code you are using, but I hope this is useful.

var request = new XMLHttpRequest();
request.open("GET", "http://yoururl");
request.onload = function () {
    if (this.status >= 200 && this.status < 400) {
        // HERE RUN THE FUNCTION YOU WANT TO RUN AGAIN
    }
};
request.send();

As far as I get it you want a certain script to run everytime the page is modified by an ajax request.

$( document ).ajaxComplete(function() {
  console.log("an ajax request was completed);
});

if you replace the console.log with your code, it will run everytime when an ajax request is completed on the document (webpage).

to check it without using jquery this should work:

also don't forget to add

@run-at document-start

to your userscript, it needs to be loaded before the webpage is running.
