title: getElementsByTagName Exclude Elements (Filter)
body: <p>I have a JavaScript selector like this: </p>
  
  <pre><code>var inputs = document.getElementsByTagName("input");
  </code></pre>
  
  <p>This works great except that I want to filter out some inputs (the ones with the class of "exists")</p>
  
  <p>How can I do this without jQuery?</p>
