A few weeks ago I posted a blog entry on my jQuery Calculation Plug-in. However, I never think I do an adequate job of describing what it does so I thought a little video might be more useful. Since I just installed Jing a few days ago, I thought this plug-in made a perfect candidate for my first Jing post!
Something I forgot to specifically mention in my demo, but which I think is really significant, is that the dynamic calculation code would work regardless of how many rows were in your table. If you only had 1 item in your basket or 20 items, the exact same code is used. The key is to use a naming convention that is consistent and easy for jQuery to parse.
My original post goes into the technical details behind the demo above, so make sure to read the post for the detailed information on what's going on.
