title: How to return a ajax result to global variable
body: <p>I'm trying to create a pagination using jquery. I want to return a ajax success response to global Variable.
  I have created a global variable and stored the response. But I cannot access outside of success block. I want to change the value dynamically, because it will retrive the data when I click the next page without refresh. Thanks in advance..</p>
  
  <p>Code : </p>
  
  <pre><code>  var tmp;
       $('table').DataTable ({
          serverSide:true,
          ajax : {
              url:'http://localhost:8000/api/feeds/1/',
              type:'GET',                
          },drawCallback : function(settings) {
  
            var api = this.api();
            tmp = api.rows({page:'current'}).data();
  
          }
        });
      console.log(tmp); 
  </code></pre>
