Answer 1

Well, first off you don't need the second document.getElementsByClssName, secondly IE has a special function.

var buttons = document.getElementsByClassName("my-button");
for(i=0;i

EDIT:

You could also use buttons array as something you create on the fly, ie :

var button1 = document.createElement( 'button' );
var button2 = document.createElement( 'button' );
var buttons = [ button1, button2 ]

// Rest of code above
