title: Separate text in input
body: <p>I have simply input in html, for example:</p>
  
  <pre><code>&lt;input class="check" type="text" /&gt;
  </code></pre>
  
  <p>I would like enter to this input text with separated by <strong>#</strong>. For example:</p>
  
  <pre><code>aaa# bbb# ccc# ddd
  </code></pre>
  
  <p>But how can I check and replace with jQuery that before # wasn't space and after # was space?</p>
  
  <p>For example:</p>
  
  <pre><code> aaa # bbb#ccc#ddd# eee
  </code></pre>
  
  <p>should replace to:</p>
  
  <pre><code> aaa# bbb# ccc# ddd# eee
  </code></pre>
  
  <p>etc. </p>
