</head>
<body>
<form id="form1" runat="server">
<script type="text/javascript">
$(document).ready(function () {
$('.rb').click(function () {
if ($('#RadioButton1').checked()) {
alert('radio button 1 checked');
} else {
alert('radio button 2 checked');
}
});
});
</script>
<div>
<asp:RadioButton ID="RadioButton1" runat="server" GroupName="GroupOne" />
<asp:RadioButton ID="RadioButton2" runat="server" GroupName="GroupOne"/>
