Jquery Returning Value to JavaScript

 Sometime we need to use the response given by AJAX,outside of AJAX(somewhere else in java script)

 here is the approach.

<script language="JavaScript" src="jquery-1.4.2.min.js"></script>
<Script language="JavaScript">
$(document).ready(f1);
 

function f1()

{var total = $.ajax({
                    type: "POST",
                    url: "add.jsp",
                    data: "num1=10&num2=20",
                    async: false
                   }).responseText; 

//use total here
}
</Script>

add.jsp

-------

<%

int sum=Integer.parseInt(request.getParameter("num1"))+Integer.parseInt(request.getParameter("num2"));

 out.println(sum);

%>
