[Proto-Scripty] Re: How to autorefresh part of a page?
if you are using ajax, then use setTimeout or setInterval , to get updated data.

Hi, I've tried the PeriodicalUpdater before and it only call the servlet twice. I have done some small research and found out that this problem only occurs in IE. However, this can be solved by using method:"post" instead of method:"get". Thanks for your help, both TJ and Peter. On Sep 17, 4:28 pm, "T.J.

And if you really need realtime feedback, you'll have to resort to either implementing Comet or a Flash based persistent messaging system like the one used in Juggernaut (http://juggernaut.rubyforge.org/). Both require more than basic web development knowledge to implement properly. PeriodicalUpdater (even with decay on the clientside, caching and etagging on the serverside) can lead the request hammering of the server (depending on the number of visitors and the time they leave your auto-updating page open). Keep that in mind. You have to wonder if the better option wouldn't be to explain to your client that web applications are stateless in nature (i.e. once they are loaded, they don't update by themselves automatically if data on the serverside is changed).

Hi, This is exactly what the PeriodicalUpdater[1] is for. If you're just starting out with Prototype, can I recommend you read the API[2] from beginning to end. It will take about an hour, and repay you multifold. [1] http://api.prototypejs.org/ajax/ajax/periodicalupdater.html [2] http://api.prototypejs.org HTH, -- T.J.
