Question

is there a way to create in jquery a callback function that is automatically called before ALL ajax request?

I need it to check if the session still active but dont want to add it to all 100+ ajax calls i already havecoded on my site.

Answer 1

You could us the .ajaxSetup() method which allows you to register a global beforeSend callback that will be executed before each AJAX call:

$.ajaxSetup({
    beforeSend: function(jqXHR, settings) {
        // ...
    }
});
