Try the below code. Enable and Disable JS in browser.
Main.aspx
<script type="text/javascript">function load() {alert("ok");}script>
<style type="text/css">div.noscript {display: block;text-align: center;color: white;font-weight: 700;background: #D53333;margin: 0 auto;padding: 4px;}style>
<body>
<form id="form1" runat="server">
<asp:Button ID="btn" runat="server"Text="Test"OnClientClick="load(); return false;" />
<noscript>
<div class="noscript"id="js-warning">
<meta http-equiv="Refresh"content="1; URL=http://localhost:58044/error.aspx">
