title: getElementsByClassName and change class of each one consecutively
body: <p>I'm using a RSS to Javascript converter so I get about 15 items with the same class and I want to change each of those for an individual class.</p>
  
  <p>something like this.</p>
  
  <pre><code>getElementsByClassName('genericclass')class = ("one")
  if("one") "alreadytaken" else ("two")
  if("two") "alreadytaken" else ("three)
  </code></pre>
  
  <p>I Hope you get the idea, and probably it's easier using random class selector right?</p>
  
  <hr>
  
  <p>This is one jQuery way to do this, I cant manage to change the classes from the div generated by the other javascript.</p>
