Need a system to rate an item on your web page? Let's implement the simple script to do that. This script is very easy to setup and modify, you only copy all JavaScript code into your web page (should save into a file for using on many pages).

When designing web site, sometimes we need to fill areas of layout with some text, and we usually do this thing by making some copy & paste on any content when meet.

But with this random code, we will create some random quotes, random texts easily through one click. Three patterns are available: text latin, silly, spanish and italian.

If you ever seen many web pages, posts of professional knowledges, specialized in skills or researches; perhaps you would see many specialized in words that they're explained after each post/page.

As a content publisher, when you have to work with specialized in articles, you'll have to spend more time to make more explanations by your hand if they're very long ones. This is reason Aaron Gustafson build this JavaScript code example, it helps us spend less than time for this job, all we have to do now is concentrate on our content, all glossaries will be done automatically.

There's another very useful JavaScript code example to content publishers: JavaScript Content Auto-Indexing using DOM.
