title: Exclude comma character from a non-whitespace string
body: <p>I need a regex expression that will validate that a string is not all whitespace and that it does not include the comma (,) character.</p>
  
  <p>I've been able to find examples that do one or the other, but not both:</p>
  
  <p><code>^(?![\s,]*$).+</code> to insure not all white space and<br>
  <code>^(.(?!,))*$</code> to exclude commas.</p>
  
  <p>I don't have the option of using code, this is a constraint on a field in a form.</p>
