How to make a variable that consists of several "divs"


I have a question regarding variables in Javascript.

When I assign a var to a ID I do it like this:

var x = document.getElementById("div_name");

But I would like to make a variable which consists of multiple 'divs'.

I thought this might work but I does not:

var x = document.getElementById("div_name"),document.getElementById("div_name2");

Can someone please help me find the right code syntax and explain why the syntax I tried is incorrect.

So, If you just want them as a list of div's you could do this:

var x = [document.getElementById("div_name"),document.getElementById("div_name2")];

Just wrap them up with [].
