title: getElementsByClassName - safe to use in 2012?
body: <p>JavaScript's <a href="https://developer.mozilla.org/en/DOM/Document.getElementById" rel="nofollow"><code>getElementById</code></a> is ok to use, I know that. But how about <a href="https://developer.mozilla.org/en/DOM/document.getElementsByClassName" rel="nofollow"><code>getElementsByClassName</code></a>? How is the browser support for that?</p>
  
  <p>Through Google I've found various homemade solutions for it, like <a href="http://robertnyman.com/2008/05/27/the-ultimate-getelementsbyclassname-anno-2008/" rel="nofollow">this</a></p>
  
  <p>As you can see, this post is four years old now, that's why I am asking. Or should I just use jQuery for stuff like that if it's available?</p>
