You can just declare extra_data as a global variable if i remember (without var before) and you can use it inside the scope of the success method, and you don’t need to pass it through methods arguments

extra_data = 'some data';
var a = {
 type : 'post',
 async : true,
 cache : false,
 dataType : 'json',
 timeout : 15000,
 contentType : 'application/x-www-form-urlencoded;charset=UTF-8',
 global : true,
 url : url,
 success : [
     function(response, textStatus, jqXHR){
       console.log(extra_data); //for example
     }
 ]
};
