in jquery when you attach an event, "this" in a callback refers to the html element that was clicked or mouseover-ed etc.
in his lib, he is saving a reference to an html element in objRef, which he uses later to set the scope. another way would be to use .apply/.call or just use jquery.

Stephen, as I wrote in the other post, to avoid these problems, you
should use these loops like this:
for (propName in obj) {
if (obj.hasOwnProperty(propName)) {
// do something with property...
}
}
