Description:
In previous articles I explained how to disable or enable all the controls on page using JQuery and many articles relating to JQuery. Now I will explain how to use regular expression to validate email address using JQuery in asp.net.
In previous articles I explained how to disable or enable all the controls on page using JQuery and many articles relating to JQuery. Now I will explain how to use regular expression to validate email address using JQuery in asp.net.
To implement this one we need to write
code as shown below in your aspx page
<html xmlns="http://www.w3.org/1999/xhtml">
<head id="Head1"
runat="server">
<title>Regular expression to validate email using jquery in
asp.net</title>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js">
</script>
<script type="text/javascript">
$(document).ready(function
() {
$("#btnValidate").click(function () {
var EmailText = $("#txtEmail").val();
if ($.trim(EmailText).length == 0) {
alert("Please
enter email address");
return false;
}
if (validateEmail(EmailText)) {
alert('Valid
Email Address');
return true;
}
else {
alert('Invalid
Email Address');
return false;
}
});
});
function validateEmail(sEmail) {
var filter =
/^([\w-\.]+)@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.)|(([\w-]+\.)+))([a-zA-Z]{2,4}|[0-9]{1,3})(\]?)$/;
if (filter.test(sEmail)) {
return true;
}
else {
return false;
}
}
</script>
</head>
<body>
<form id="form1"
runat="server">
<div>
<asp:TextBox ID="txtEmail"
runat="server"/>
<asp:Button ID="btnValidate"
runat="server"
Text="Validate"
/>
</div>
</form>
</body>
</html>

If
you observe above code in header section I added script file link by using that
file we have a chance to interact with JQuery and in the script we have btnValidate button click function
which is used to validate email address based using JQuery in asp.net.
