In the example below when we press the button the first time, we use the .ajaxSuccess() method to set up a global event handler to be run for each Ajax request. The handler is fired on successful completion of a request and we output a message giving some information about the request.


$(function(){
  $('#btn6').one('click', function(){
    // Register global event handler and attach to 'div6' element
    $('#div6').ajaxSuccess(function(event, jqXHR, ajaxSettings) {
       $(this).append('Triggered the ajaxSuccess() global event handler for url: ' 
                      + ajaxSettings.url + '. Status: ' + jqXHR.status + '. Status text: ' 
                      + jqXHR.statusText + '.<br><br>');
    });
