title: How to disable any whitespace in a input?
body: <p>I have the following pattern </p>
  
  <p><a href="https://codepen.io/anon/pen/ErpxLN" rel="nofollow noreferrer">https://codepen.io/anon/pen/ErpxLN</a></p>
  
  <pre><code>/^(!?=.*\d)/
  </code></pre>
  
  <p>it match every time i put a character.</p>
  
  <p>I would like to negate it. (or find another pattern)</p>
  
  <p>The end result would be -> NOT allowing ANY whitespace. So when there is a white space, at any point in the string, the input throw an error</p>
