Solution 1

You can call [WebMethod] from javascript (without jquery) with PageMethods.Test().

To call webmethod from javascript you have to add
<asp:ScriptManager ID="ScriptManager1" runat="server" EnablePageMethods="true">
</asp:ScriptManager>
in your aspx page.

hey this my aspx page code

<%@ Page Title="Home Page" Language="C#" MasterPageFile="~/Site.master" AutoEventWireup="true"
CodeBehind="Default.aspx.cs" Inherits="Test._Default" %>

<asp:Content ID="HeaderContent" runat="server" ContentPlaceHolderID="HeadContent">

<asp:Content ID="BodyContent" runat="server" ContentPlaceHolderID="MainContent">
<asp:ScriptManager ID="ScriptManager1" runat="server" EnablePageMethods="true">

Welcome to ASP.NET!

<p>
<asp:Button ID="Button1" runat="server" Text="Call method" OnClientClick="callMyMethod()" />

</p>
<%--<p>
You can also find documentation on ASP.NET at MSDN.
</p>--%>
<script type="text/javascript">
function callMyMethod() {
PageMethods.method();
}
</script>
