How to set global variables in jQuery/JavaScript? -

-

i have ajax function:

    $.ajax({         url: 'http://localhost/process.php',         type: 'post',         data: '',         success: function(output) {  var animal = output          }     });

i var animal set globally can call anywhere on page outside ajax function's success callback. how this?

declare outside of function or jquery construct

var animal = null;  $(function(){     $.ajax({         url: 'http://localhost/process.php',         type: 'post',         data: '',         success: function(output) {             animal = output         }     }); });
