<html xmlns="http://www.w3.org/1999/xhtml">
<head id="Head1" runat="server">
    <script type="text/javascript" src="//code.jquery.com/jquery-1.10.2.min.js"></script>
    <title>jQuery AJAX call to insert records to database</title>
    <script type="text/javascript">
        $(document).ready(function () {
            $('#btnsubmit').click(function () {
                var name = $('#txtName').val();
                var age = $('#txtAge').val();
                var sex = $('#txtSex').val();
                $.ajax({
                    type: 'POST',
                    contentType: "application/json; charset=utf-8",
                    url: 'Default.aspx/InsertData',
                    data: "{'name':'" + name + "','age':'" + age + "','sex':'" + sex + "'}",
                    async: false,
                    success: function (response) {
                        $('#txtName').val(''); $('#txtAge').val(''); $('#txtSex').val('');
                        alert("Record saved successfully..!!");
                    },
                    error: function () {
                        alert("Error");
                    }
                });
            });
        });
    </script>

    <style type="text/css">
        #btnsubmit {
            text-align: center;
        }
    </style>

</head>
<body>
    <form id="form1" runat="server">
        <div>
            <table align="center">
                <tr>
                    <td>Name  </td>
                    <td>
                        <asp:TextBox ID="txtName" runat="server" ClientIDMode="Static"></asp:TextBox>
                    </td>
                </tr>
                <tr>
                    <td>Age  </td>
                    <td>
                        <asp:TextBox ID="txtAge" runat="server" ClientIDMode="Static"> </asp:TextBox>
                    </td>
                </tr>
                <tr>
                    <td>Sex </td>
                    <td>
                        <asp:TextBox ID="txtSex" runat="server" ClientIDMode="Static"> </asp:TextBox>
                    </td>
                </tr>
                <tr>
                    <td>
                        <input type="button" id="btnsubmit" value="Submit" />
                    </td>
