No, what he's saying is the "this" in $(this) is actually a reference to the
DOM element.
So, in the code:
$("#myDiv").click(
function (){
// spit out the actual DOM element
alert(this);
}
);

The above would not work. Due to jQuery's chaining mechanism, $("#myDiv")
always returns a jQuery object--so you need to use either the get() method
or reference the jQuery object by it's array shortcut to get to the actual
DOM element.
>or should it always be one of:
> $("#myDiv").get(0).selectedIndex;
> $("#myDiv")[0].selectedIndex;
You would need to use on of the two methods you listed above to get to the
selectedIndex property.
