如何将数据传递给AJAX调用

Question

Can anyone tell me how to pass data to the jsp making the AJAX call ? This is what I am trying:

Here is my AJAX call:

     $.get("gridedit.jsp", { before: "row", time: "2pm" })
               .done(function(data) {
                 alert("Data Loaded: " + data);
               });

here is my gridedit.jsp

    <% String b=request.getParameter("before");

    if(b.equalsIgnoreCase("row"))
     {
System.out.println("ROW ROW ROW your boat");
        out.println("bummer");
    } %>

i want to store the value returned from gridedit.jsp into a javascript variable. How should I do this ?

please help

thanks

    $.ajax({
                url: "gridedit.jsp",

                async: true,
                cache: false,
                type:"GET",
                data: {
                    before:'row',
                      },
                      error: function(msg) { alert(msg); },
                      complete: function (xhr, status) { alert('complete: '+status); }

            });

Answer 1

It is in a variable, the data variable in the anonymous function passed to .done()

Whatever you need the data returned by gridedit.jsp to do, the easiest way to have anything done with it is to use it in that function. Right now all you are doing with it is making a popup containing the returned data.
