Some ways to call it

To get all a elements in the document with a info-links class.
    getElementsByClassName(document, "a", "info-links");
To get all div elements within the element named container, with a col class.
    getElementsByClassName(document.getElementById("container"), "div", "col"); 
To get all elements within in the document with a click-me class.
    getElementsByClassName(document, "*", "click-me");
