markitup

markitup is an interesting script that allows you to change a textarea html element and turn it into a markup editor. You can use it to edit Html, Textile, Wiki Syntax, Markdown, BBcode or even your own Markup system.

The script is built on the jQuery library and does a good job of using the library. In case you are unfamiliar with the library you can learn more about it here.

You can see quite a few examples of markitup here. Also, you can read the documentation for the script here. Click here to go to the markitup web page where you can download the script.

This script would be very useful if you are creating a CMS, Forum or any system where your users would need to edit markup.
