Regex

[kyern]

I am trying to find a regex that would allow only the characters allowed in the left half of an email address. It would fail if there was an @ sign or other special character not normally allowed. If anyone can help it would be very appreciated.

Also if anyone knows of a good resource to learn about building regex that would be great.

Try this

function alpha_numeric_dash_undrscr() { 
  //Accepts a-z, A-Z, 0-9 - _
  var re = /^[\w\-]+$/;
  return re.test(value);
}

Pass the value in you want to test and it will return true or false.

At my age I still learn something new every day, but I forget two others.

I would suggest include \. in your regex.

Excellent the combination of those worked perfect.
