How do I inplement javascript $each() in C2?

In the example below in Edge Animate*, a different image is loaded according to what button is clicked. How could I implement that in C2?

* Edge Animate uses a slightly modified javaScript where sym is the stage symbol. The individual button elements are all children of the div.

I do not seem to find a way to address a series of buttons in this way.

var buttons = sym.$("buttons").children();     

$.each(buttons,function(i){
	$(this).on("click", function(){ 
			// do something when one of the button is clicked	
			sym.$("images").css({"opacity":0.00});
			sym.$("images").animate({"opacity":1.00},700).attr('src',"images/image" + i + ".png");				
	});	
})[/code:28umjxwf]
