title: Finding the index of the element with class in native Javascript
body: <p>Is there a way to get the index of class name (I.e. the third element with the class "className" would be 3 without using jQ?</p>
  
  <p>I don't know jQ, and I don't have time to learn it right now, and I don't want to include code into my code that I don't understand at least some.</p>
  
  <p>Thanks.</p>
  
  <p>BTW, I've used jQ instead of spelling it out so those results can be filtered out in Google should somebody have the same question. If I spelled it out, and somebody used the NOT operator in Google, this one would also disappear.</p>
