$("#myElement) returns jQuery object and $("#myElement")[0] returns
DHTML object.
Here is a sample on how to access alt attribute
jQuery $("#myElement").attr("alt")
vs
DHTML $("#myElement")[0].alt
Both code return the same value. Correct me if i am wrong, I think
the DHTML version is faster than the jQuery one.
