Jquery stop function
===

I have a jquery function like this:
 
    function get()
     {
    $.ajax({
         url: 'get.php',
         success: function(data) {
         $('#get').html(data);
         $('#get').fadeIn(2000);
         setTimeout(posts,2000);
        }
        });
     }
     get();

I want to stop this function when i click on a certain element in a webpage, how would i do this. 

Thanks
