How to use Server.MapPath in jQuery JavaScript when deploying on Hosting Server

I am using WebMethod on my ASPXpage and I call it from jQuery on the same page like this:

    $.ajax({
                type: "POST",
                url: "Mypage.aspx/GetSomeData",
                contentType: "application/json; charset=utf-8",
                data: parameters,
                dataType: "json",
                success: AjaxSucceeded,
                error: AjaxFailed
            });

This works fine in my debug environment, but when I deploy on the hosting site it does not. The problem seems to be in the URL because on the server the path would be different. So I used Server.MapPath in various ways but none of them worked.

E.g

url: '<%= Server.Map开发者_Go百科Path("MyPage.aspx/GetSomeData")%>',

When I use the above code snippet it does not work on my machine. MyPage is in the root directory.

You probably just need a tilde to start at the root of the app:

url: '<%= Server.MapPath("~/MyPage.aspx/GetSomeData")%>'

EDIT

Try using:

<%= ResolveUrl("~/MyPage.aspx") %>
