if(document.user.emailid.value=="")
{
   alert("Enter your email id");
return
}
else {
//Now check if email is valid 
if (!(/^\w+([\.-]?\w+)*@\w+([\.-]?\w+)*(\.\w{2,3})+$/.test(document.user.emailid.value))) 
{
alert("The email you entered is not a valid email address.");
return
}
}

hi .........
i used the code u mentioned but still there is no change,
it still accepts [e-mail] as a valid email id.
isnt there any way 2 set it in such a way tht it accepts only email id with one com in its domain?
thanks

Hi Eric,
As per this expression, the character "-" is invalid in a email field. What change should I make to the above regular expression to make "-" (or any other character for that matter) as a valid character?

Thanks

I think I figured it out. Will this solve the problem? Please confirm.

var StrRE = /^[\w.\-]{1,}[@][\w\-]{1,}[.][\w.\-]{1,}$/;
