The length property in a jQuery object or $("#emplist").length refers
to the number of elements that the jQuery selector matched. So, if
your selector was "div", $("div").length would be the number of div
elements in your document. $("#id") doesn't return a single DOM
element, it returns a jQuery collection, with one DOM element in it.
What WOULD work is: $("#emplist").get(0).length. ".get(0)" returns the
first (0th) DOM element which, since there is only one element, will
be your "#emplist" element.
