title: Example of a regular expression for phone numbers
body: <p>I'm very new to javascript, I just want a reqular expression for validating phone numbers for one of my text field.</p>
  <p>I can accept <code>-+ () 0-9</code> from users, do you have regex for this one or a regex for phone numbers better then the one i need?</p>
  <p>Thanks in advance.</p>
