Cloning Facebook "x new posts" feature

AdMMM

On your homepage of Facebook, whenever there are new status updates posted by friends, it dynamically notifies you on your homepage and when you click the link, the new updates appear.



I regularly attend events where I offer live text updates on websites as the event progresses (eg: http://www.ladbrokeslive.com ) and my ability to use the term "live" is severely limited by the requirement of the user to refresh the page on a regular basis.

The "Show X new posts" feature would be the perfect feature to deliver live content to visitors as well as cutting down on bandwidth by saving the need for refreshing the page.

Are there any current open examples of such a script/feature?

Start by googling AJAX. It's a combination of javascript and sql stuff, very web 2.0

I'm not that new to the game . I had hoped that this particular feature would be very desirable and that someone would have created a class for it

Maybe Ajax polling using jQuery and setInterval might be what you are looking for.
It's pretty straight forward to do if you have some knowledge of jQuery.

Didn't realise you knew about ajax AdMMM, you can never tell unless you tell us in the OP!

Very straight-forward to create something like this in jQuery, it's also possible to reload just the top section of the page is required using similar methods, instead of just displaying a link to load the new content.

If you know jQuery and a back end language you could probably knock something together in about 30 minutes, I've done some similar stuff for a client before.

It's also not really something that would be all that generic, which is probably why there is no class/jquery plugin for it (that I know of), as it all depends on how you would poll and what the server request and response mechanisms would be.
