title: Regex to allow letters and numbers but not numbers alone
body: <p>I'm trying to write a regex for javascript which will allow letters and numbers but won't allow numbers alone.</p>
  
  <p>So '12 Test Street' would validate, as would 'test street' but not '12'.</p>
  
  <p>Not that familiar with regexs so I've no idea where to start. I managed to write:</p>
  
  <pre><code>^([A-Za-z\d\s]+[A-Za-z\s])+$
  </code></pre>
  
  <p>That does work to a point but if a space is then added to the end of the numbers, it will validate again.</p>
