APEX Star Rating - Amazon style

Recently there were two threads on the APEX OTN Forum regarding the implementation of an Amazon-style star rating mechanism (this thread and this thread).
Using this jQuery plug-in that implementation is not so difficult. The first step (of course you've installed jQuery) is to install the JavaScript and CSS of the plug-in. To create a demo I added two columns to the DEMO_PRODUCT_INFO table : RATING and VOTES.
The second step is to create a PL/SQL function and use that in your select statement to show the current rating:

create or replace function GET_STARS
( pID in NUMBER
, pRating in NUMBER
) return VARCHAR2
is
l_retval varchar2(2000) :='';
BEGIN
FOR i in 1..5 LOOP
 IF i = pRating
THEN l_retval := l_retval ||'<input class="star" id="'||pID||'" name="star'||pID||'" value="'||i||'" checked="checked" type="radio">';
 ELSE l_retval := l_retval ||'<input class="star" id="'||pID||'" name="star'||pID||'" value="'||i||'" type="radio">';
 END IF;
END LOOP;
RETURN l_retval;
END;

Then add a click event to the elements with a 'star' class

$(function(){
 $('.star').click(function() {
   saveRating( $(this).attr("id"), $(this).children().attr("title") );
   votes = Number($(this).parent().parent().next().html()) + 1;
   $(this).parent().parent().next().html( votes );
 });
});

where saveRating is just a 'regular' AJAX OnDemand process that calls a PL/SQL Procedure that does the actual update.
The result is quite good: You can hover over the stars and a click saves the rating (of course you would need another data model to save and calculate all ratings and prevent users from rating more than once, but that's for later).
