title: Regex validation for comma separated string
body: <p>I need to validate and input string client side.</p>
  
  <p>Here is an example of the string:</p>
  
  <pre>1:30-1:34, 1:20-1:22, 1:30-1:37, </pre>
  
  <p>It's basically time codes for a video.</p>
  
  <p>Can this be done with regex?</p>
  
  <p>Banging my head against the wall...</p>
