ASP.NET Web Forms Method With JQuery Ajax Request Failed

Question

I want to call code behind method from client side ajax request. It returns success but it never goes inside this method. Here is my code:

Code Behind:

        [WebMethod]
        public static void Test()
        {
            var ceva = "I was called";
        }

javascript ajax request:

            $.ajax({
                type: "POST",
                url: "/Default.aspx/Test",
                contentType: "application/json; charset=utf-8",
                success: function(data) {
                    alert('success');
                },
                error : function(data , data2 , data3) {
                    alert('failed');
                }
            });

How do you verify it never executes the method? Did you put a Debug.Print statement in there...? — deostroll

Try to add data property to ajax (could be an empty value, like data: {}) and add dataType: "json" — Pavlo

You checked with firebug or the developer toolbar, in the net section, the call? maybe the content type or something else is wrong in the call — Daniele

Please try: (tested and working)

        $.ajax({
            type: "POST",
            url: "Default.aspx/Test",
            contentType: "application/json; charset=utf-8",
            success: function(data) {
                alert('success');
            },
            error : function(data) {
                alert('failed');
            }
        });

code:

[WebMethod]
[ScriptMethod(ResponseFormat = ResponseFormat.Json)]
public static string Test()
{
        return "I was called";
}
