The first thing you need to do is use the FireBug console. That will tell you what the error is.

But your code won't work because your return type is void. You actually need to return something back to the client. Change it to this:

[System.Web.Services.WebMethod]
[System.Web.Script.Services.ScriptMethod]
public static string Call(string value)
{
    var x = value;
    return x; // Silly example
}

First of all this script won't return anything because you're using the wrong id of a server control. When a server control is rendered, it's id changes. Try using :

$("#<%=btn.ClientID %>")

You have another problem. You're calling an overloaded web method, so you need to pass some data :

data: "{'value': 'somevalue'}",

Hope this will help.

Does this path scripts/jquery-1.2.6-vsdoc.js give you proper jQuery file? It looks like you're trying to load vsdoc file as a normal library.
