title: Javascript Validation for a phone number (Numbers, spaces, dots, hyphens)
body: <p>So I have this validation for alphanumeric's <code>(/^[A-Za-z0-9,\+-]+$/)</code> however I want a validation for a phone number which only allows Numbers, Spaces, Dots and Hyphens.  What code would I use to check for those.</p>
  
  <p>Thanks
