Matt, this sounds really cool. Your version might be just what we need
to integrate into exhibit 3. Can you post links to some working
examples people can play with?

I started using timeline a while ago and dug in deep. I love the
widget, but I really disliked the way it was loading the javascript
and how its script block needed to be in the head section. I tore out
the timeline code from the overall Simile project and removed much of
the base code that wasn't needed or was just a duplicate of what
jquery has. I've changed the way class methods are defined to be more
streamlined and the overall result is now one file that is 153kb
minified and 44k zipped. This is a significant size difference from
the Simile version, which loads faster on the iPad. This code version
also has tablet touch support as provided in other threads on the web.
I've completely removed all support for doing ajax directly from
Timeline as its just more mainstream to use something like
$.load(...).done(function(json){...}). This is an example of removing
stuff from timeline that jquery already does.
Another thing removed is the history stuff which forced another query
on the server and wasn't really used in timeline anyway.
Also, the code no longer tries to load its own version of jquery. My
thinking is, if you cant properly setup jquery on the page, you
probably aren't ready to use timeline. I think the main developer
should be crystal clear on what version of jquery is being used in
their project. That code was just bloat.
I've also setup the creation of the timeline as a real jquery plugin.
All examples I've converted over work, and my own app which pushes
the edges of the timeline works with the new code.
I'm not sure if this new code should be setup as a branch to the main
project or just shared somewhere else. I want to take timeline
further than it is now, including support classes in .NET for ASP.NET
classic and MVC. Right now I'm thinking I'll just host this version
on another site and let it go from there.
I'm adding better event notification to support having other things on
the page show data related to the events showing on the page. For
example, all financial transactions visible on the timeline are
summarized in a table below the timeline.
I've also added support for event grouping by having bands that dont
have to have a timeline painter. Put different events on each band
and only have the bottom band have the date tic marks. This groups
events well.
I also need to add support for paging events rather than loading all
events into the timeline at once. As the user scrolls through time,
the timeline should be able to have events added and removed
dynamically to keep the total # of events (and DOM elements) actually
rendered down to a minimal. I worked on the Nitobi Grid which did
virtual scrolling with data paging via ajax and it worked well. I see
it as critical for timeline to support this really well.
