Jquery - BBC +/- buttons

as my boss loves the bbc site (www.bbc.com), does anyone have any suggestions for creating the functionality for controlling how many items are in the list using the plus and minus buttons? When clicking plus it will add more items, when clic开发者_如何学Pythonking minus it wil remove the bottom item.

It looks like this is done using Jquery, anyone have any suggestions?

Thanks

BBC loads all the items and just marks some of them as hidden using a .hide CSS class. It's not very sophisticated. So your jQuery will go something like:

Plus

$("#myDiv li.hide:first").removeClass("hide");

Minus

$("#myDiv li:not(.hide):last").addClass("hide");
