E-mail address validation

[Vivek Puthiyonnan]

How can i validate email addresses using javascript ?

Here's something age-old. I'm sure it can be improved (e.g., it doesn't handle internationalized domain names) but it should give you a start.

function checkEmail (name) {
var email = name.toLowerCase();
// remove any white space
email = email.replace(/\s/gi, "");
 
if (email.search(new RegExp("^\\S+@([-\\w]+\\.){1,4}[a-zA-Z]{2,6}$")) != 0) return false;
 
return true;
}
