Jquery Ajax Boolean Variable is not working well

 $.validator.addMethod("checkUsername", 
   function(value, element){
    var test;     //we want to use this test is like boolean variable
    $.ajax({
        type:"GET",            
        data: 'name='+ value,
        url: "master/ValidationDepartment.jsp",
        success: function(response){  
               test = true;   //assign this value is true                
        },
        error: function() {
               test = false;  //assign this value is false 
    }
    });
         //alert(test);     // bt now this time test value is undifined
    return test;
  }, 
"Departmentname Already Exists."
);
});

I also tried with var test = true. If we declare test = true every time its value is true.

The .ajax() runs asynchronously and your value will be returned immediately .You can write a callback function in the success or error handler and update the variable . You can set async:false but then it will block till the AJAX response returns.

Seeing as ajax calls will run asynchronously, the value of test will only change after your function returns. To prevent this from happening, set async: false in the options of your ajax request.
