The Selected() Plugin

Part of the code I write requires a sort of radio button or toggle button functionality. The core ability is to be able to set an item as selected (or checked, active, clicked, etc.). I ran into this a lot and found myself writing the same simple code over and over again until I created the selected plugin.

Now i can simply write this with jQuery:

$("a").selected(true);
var isSelected = $("a").selected();

Of course this led to being able to have a group of buttons with only one selected at a time:

$("a.tab").selectedGroup();

I have the plugin up on GitHub with a little more explanation and a demo:

Let me know what you think.
