Validating email addresses using jQuery and regex

Question

I\'m not too sure how to do this. I need to validate email addresses using regex with something like this:

[a-z0-9!#$%&\'*+/=?^_`{|}~-]+(?:\\.[a-z0-9!#$         


        

Answer 1

We can also use regular expression (/^([\w.-]+)@([\w-]+)((.(\w){2,3})+)$/i) to validate email address format is correct or not.

var emailRegex = new RegExp(/^([\w\.\-]+)@([\w\-]+)((\.(\w){2,3})+)$/i);
 var valid = emailRegex.test(emailAddress);
  if (!valid) {
    alert("Invalid e-mail address");
    return false;
  } else
    return true;
