Nobody addressed the actual problem which was happening, to explain why the alert was issued.

This code: document.getElementById("foo").click = new function() { alert('foo'); }; assigns the click property of the #foo element to an empty object. The anonymous function in here is meant to initialize the object. I like to think of this type of function as a constructor. You put the alert in there, so it gets called because the function gets called immediately.
