How can I use the Ajax response in another function

I have a dropdown list with values from the database. I used AJAX to dynamically display the price of the selected item form the database. I want to use the p开发者_StackOverflow中文版rice value for further processing

 var dataForFuture;

 $.get('ajax/test.html', function(data) {
      dataForFuture = data;
      // other code...
 });
