title: Set a variable based on the #of a url -- window.location.hash
body: <p>so lets say i have a url www.hello.com#one</p>
  
  <p>i know i can grab the has value</p>
  
  <pre><code>var hash = window.location.hash;
  alert (hash);
  </code></pre>
  
  <p>but rather then write (i know the below is not propper code):</p>
  
  <p>if var hash = one then set var hashValue to 1</p>
  
  <p>else</p>
  
  <p>if var hash = two then set var hashValue to 2</p>
  
  <p>else etc etc</p>
  
  <p>is there a better way to write this.</p>
  
  <p>Cheers</p>
