How to validate email address using jQuery Samples and examples

In this article I'm going to explain how to validate the email address using jQuery.
To validate the email address, I have created a separate function to check whether email id is valid or not.
Email Validation is done using Regualr expression.


<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
    <title>Untitled Page</title>
    <script type="text/javascript" src="jquery-1.2.6.js"></script>

    <script type="text/javascript">
    $(document).ready(function() {
   $('#Button1').click(function() {
        var vtxtEmail = $('#txtEmailID').val();
        if ($.trim(vtxtEmail).length == 0) {
            alert('Plz enter valid email address!');
            e.preventDefault();
        }
        if (TovalidateEmail(vtxtEmail)) {
            alert('This is  not  valid email id');
        }
        else {
            alert('Invalid Email Address');
            e.preventDefault();
        }
    });
});


function TovalidateEmail(vtxtEmail) {
    var filterexpression = /^([\w-\.]+)@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.)|(([\w-]+\.)+))([a-zA-Z]{2,4}|[0-9]{1,3})(\]?)$/;
    if (filterexpression.test(vtxtEmail)) {
        return true;
    }
    else {
        return false;
    }
}?
    </script>
</head>
<body>
    <form id="form1" runat="server">
    <div>
        <asp:TextBox ID="txtEmailID" runat="server"></asp:TextBox>
        <asp:Button ID="Button1" runat="server" Text="Button" />
    </div>
    </form>
</body>
</html>
