javascript - Calling Code-Behind function from AJAX directly without page load -

i trying call code behind function directly. @ moment able call function pageload event of ajax.aspx.vb , pass response through variable on ajax.aspx <%= m_result %>. works fine. however, not want go through pageload event, target function directly without having put data <%= m_result %>. possible?

i using dotnetnuke functionality comes ascx controls. so, in ascx control have ajax as:

<script type = "text/javascript">     function jsfunction() {         var xx = 1;             $.ajax({                 type: "post",                 url: "/top3/desktopmodules/top3all/ajax.aspx/gettestdata",                 data: { 'spageindex': xx},             }).done(function (response) {              onsuccesstest(response);             });     }     function onsuccesstest(response) {         document.getelementbyid("<%= lbltest.clientid%>").innerhtml = response; } </script> 

in ajax.aspx.vb:

 protected m_result string = ""   protected sub page_load(byval sender object, byval e system.eventargs) handles me.load          dim smoduleidreferrer string         if not httpcontext.current.request.urlreferrer nothing             strurl = httpcontext.current.request.urlreferrer.tostring              dim spageindex integer             if integer.tryparse(request("spageindex"), spageindex)                  gettestdata(spageindex)             end if           end if     end sub   <system.web.services.webmethod()> _  public shared function gettestdata(byval name integer) string         m_result = "some test"         return m_result     end function 

in ajax.aspx:

<%@ page language="vb" autoeventwireup="false" codebehind="ajax.aspx.vb" inherits="christoc.modules.top3all.ajax" %> <%= m_result %> 

after adding <system.web.services.webmethod()> @david says, try changing js use pagemethods, check answer, there can find need.

hope help
