Category: Ajax, Java, Showcase, XmlHttpRequest is an RSS aggregator, and has added a new “Ajax” option that a user can choose in settings.

Their article discusses how they added support for Ajax to their site.

By default, if you mouseover an RSS entry title, a tooltip pops up showing you a summary of the post, and the data was grabbed when the page is loaded.

If you turn on “Ajax mode”, then it gets that data on demand.

It is kinda funny to have one “ajax mode” on a site. It should probably be “lazy load summaries?”.

This brings up the question of when it makes sense to just preload the data, versus going back at runtime. In this situation it probably doesn’t make a lot of sense. Although you could argue that most users will only mouseover a COUPLE of elements, it wouldn’t make a lot of difference to download that data at first.

It would make a lot more sense if that sumamry data changes a lot, as then you are really getting the latest data.

It seems like Convea is finally waking back up! They had a very cool app out a long time ago and now there’s some shots up on their site.

Looks pretty inspiring actually.
