I've tried your regex in Chrome, Firefox and IE, and all three browsers are happy with it. Where did the error message come from?

[no name] 23-Jan-14 6:12am

really ????? how man, I am using chrome..

[no name] 23-Jan-14 6:13am

Same error in ff

I just pasted the line into the Javascript console, then used regex.exec() to test a couple of strings.

Are you sure this is being executed as Javascript, and not on the server?

Email Validation Expression : ^[a-z0-9_\\+-]+(\\.[a-z0-9_\\+-]+)*@[a-z0-9-]+(\\.[a-z0-9]+)*\\.([a-z]{2,4})$

Try below code to validate your email:

function validatetoemail(my_email) {
var filter = /^[_a-z0-9-]+(\.[_a-z0-9-]+)*@@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,4})$/;
if (filter.test(my_email)) {
return true;
}
else {
return false;
}
}

hope it will work also for you.

you can use below syntax for email regular expression validation in jquery:

var regx = /[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,4}/igm;
if(regx .test(email here)){ //do something }

try this one

C#

 <script type="text/javascript">
        function validateCaseSensitiveEmail() {

            var email = document.getElementById('txtEmail').value;
            var reg = /^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,4})$/;
            if (reg.test(email)) {
                alert("Valid");
            }
            else {
                alert("In Valid");
            }
        } 
</script>
