Frame 2 - Filtering the List

Note: This frame does NOTHING first time around.

This is where the link filtering happens. This is the only frame in this entire project that is really unique and that I can take credit for. Although to be honest, I got the idea from Microsoft's 'Help' index system, where this same effect happens. I liked it. I wanted one. So I made one. There are no really original ideas are there? Just new implementations of old ones.

The logic:
Here is where I sat down with pencil and paper and pre-thought out exactly what I wanted the script to do in order to perform the filtering list. In many cases, I highly recommend sitting down with pencil and paper BEFORE touching the computer. You will end up saving yourself a LOT of time.

It also helps to break large problems into the smallest possible pieces. The individual components of how this works were easy to solve. When I first though 'Hey this is what I want to do...' the overall project was to complex for me to solve all at once. So here are the individual components I broke the problem down to to be more easily programmed:
I decided:
  1. When the user types, I need to keep track of what he types live.
  2. As soon as it changes (not all the time -- to save on CPU processing -- no use continually running this code -- ) start checking.
  3. Checking involves the following: comparing the amount of characters that have already been typed (say there are five) in five character chunks against the items in the list.
  4. If a match is found, add that item AND ITS LINK to the new list.
  5. I immediately decided I wanted this to work in a non-case sensitive manner.
Easy, right?
