Answer

On the click of the HTML Submit button, you will need to iterate in the following way

<html xmlns="http://www.w3.org/1999/xhtml">
<head id="Head1">
    <title></title>
    <script type="text/javascript" src="http://ajax.aspnetcdn.com/ajax/jQuery/jquery-1.5.2.min.js"></script>
    <script type="text/javascript">
        $("#Submit").live("click", function () {
            $("form[id$=form1] input").each(function () {
                switch ($(this)[0].type) {
                    case "text":
                        var val = $(this).val();
                        break;
                    case "checkbox":
                        if ($(this).is(":checked")) {
                            var val = $(this)[0].id + ": " + "checked";
                        }
                        break;
                }
            });
            return false;
        });        
    </script>
</head>
<body>
    <form id="form1">
    <div>
        <fieldset>
            <ol>
                <li>
                    <label class="left">
                        First Name
                    </label>
                    <input type="text" id="FirstName" runat="server" /></li>
                <li>
                    <label class="left">
                        Last Name
                    </label>
                    <input type="text" id="LastName" runat="server" /></li>
                <li>
                    <label class="left">
                        Email
                    </label>
                    <input type="text" id="Email" runat="server" /></li>
                <li>
                    <label class="left">
                        Phone
                    </label>
                    <input type="text" id="Phone" runat="server" /></li>
