Start here and make sure you're wired up correctly: ASP.NET and jQuery to the Max[^]

Then, make sure you're doing something with your response (for example, you'll want to do something when your if statement in javascript evaluates to true...you aren't doing anything there).

The method you call (depending on your config) should be marked with WebMethod and should be public.

Make it more simple to start. There is a really good sample (with sample json documents) on the JSON web site: http://www.json.org/[^]

Cheers.

Hi,

Normal C# code behind methods, you cant access from AJAX or Jquery. So we need to create method with attribute '[webmethod]'

Ex:

C#

[Webmethod]
Public static void chatHeartbeat()
{
string items = "";
items = items + "\"s\":\"0\",\"f\":\"{" + message.userfrom.ToString() + "}\",\"m\":\"{" + message.message + "}\"";

HttpContext.Current.Response.Write("{ ");
Response.Write("\"items\":[" + items + "]");
HttpContext.Current.Response.Write(" }");
Response.End();

}

So now u you can access from any where.
thank you.
