Tired of adding even and odd classes to your tables to distinguish the rows? This JavaScript will do it for you automatically. You can even use it with lists!

This JavaScript will save all of your form fields in a cookie. It includes all text fields, radio button selections, checkbox values, etc. When your visitor returns, all form fields are automatically repopulated with the same value that they entered on their last visit.

You can specify any number of links, and they can open in the same window or a new one. A JavaScript cookie is used to track which links are visited. The JavaScript cookie is erased when the browser is closed.

This collection will help you to set, get, and delete cookies. It's a nice little collection that should prove to be invaluable.
