[Solved] Javascript email validation does not work

by


Like suresh suggested, you should remove the quotes (“) around your regex string.
So your first line should be:

var re = /^(([^<>()[\]\\.,;:\s@\"]+(\.[^<>()[\]\\.,;:\s@\"]+)*)|(\".+\"))@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\])|(([a-zA-Z\-0-9]+\.)+[a-zA-Z]{2,}))$/;

I produced a working example below:

<script>
function test()
{
  var re = /^(([^<>()[\]\\.,;:\s@\"]+(\.[^<>()[\]\\.,;:\s@\"]+)*)|(\".+\"))@((\[[0-9]    {1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\])|(([a-zA-Z\-0-9]+\.)+[a-zA-Z]{2,}))$/;
  var email= "[email protected]";

  if (re.test(email) == false) {  
    alert("invalid email address");
    return;
  }
  alert("valid address");
}
</script>
<button onclick="test()">TEST</button>
