title: Oninput data matches regexp pattern
body: <p>I validate vehicle VIN by using this expression:</p>
  
  <pre><code>/^X7L[A-Z0-9]{14}$/g
  </code></pre>
  
  <p>But I'd like to do validation every time user typing in input field: user won't get error, until VIN is matches pattern. Could you please help me with regular expression for it?</p>
  
  <p>Thanks</p>
