actually, i think the most efficient way to do this is to mark the questions
and answers with grouped id's:
<div id='q14' class = 'question'></div>
<div id='a14' class = 'answer'></div>
and then you could do:
a_id = 'a'+this.get('id').substr(1);
this is much simpler and more efficient than creating an array of all
answers and question, and IMO more semantic as well.
if you anticipate a question will be clicked multiple times than element
storage can be a good solution, but in a q-a scenario i think most times
element storage is an overkill.
