Adding a general parameter to all ajax calls made with jQuery

Question

I'm using AJAX to load data from the server as needed. I'm currently working on updating the server software to the latest version. One of the things I noticed that has changed is that every request now requires me to pass along a token. This means I have to add a new parameter to every request. I'm hoping to achieve this by a general method, without having to modify every single AJAX call.

Any pointers?

Answer 1

You could use the $.ajaxSetup method as illustrated in the following article.

Answer 2

What you're looking for is a Prefilter, here's a sample from the page:

$.ajaxPrefilter( function( options, originalOptions, jqXHR ) {
  // Modify options, control originalOptions, store jqXHR, etc
});

This requires JQuery 1.5.
