Question

I am doing a cross-domain fetch from a ASP.NET page using Jquery-JSONP

My ASP.NET page looks like this;

    public partial class Test : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            Response.Write("functionName({'test_param':12345});");
        }
    } 

This is hosted on my server as test.aspx

I am now using JQuery from localhost and trying to fetch the data from test.aspx like this;

            $.ajax({
                dataType: 'jsonp',
                url: 'http://abc.com/GTalk/test.aspx?callback=?',
                success: function () {
                    alert("Success");
                },
                error: function (x, y, z) {
                    alert("error" + x.responseText);
                }
            });

I am getting an error x.responseText = "undefined"
The error, z, is Error: jQuery171008073005825281143_1328259709467

I am not able to figure out what mistake I am doing. I am a newbie.

Thanks.

Instead of “functionName” on serverside you must print the function-name you receive via the GET-params as callback-parameter(jQuery171008073005825281143_1328259709467 in that case).

You can’t hardcode the name, it differs on every request)
