Ajax.PeriodicalUpdater does not extend from Ajax.Updater, so it does not support the evalJSON, and other methods, is that correct? So you are limited in someways, with respect to Ajax.Request
Feel free to slap me around Chris (go easy though :) )... I'd try this by running a PeriodicalExecuter which called an Ajax.Request method. Then inside of the Ajax.Request parse the return JSON (or whatever return form you are using), place the value in the target DIV, and also place the value in a hidden Form element. Each call of Ajax.Request at the specified interval could then check the hidden Form value (last value updated), and you could perform your comparison with the new value, then complete whatever new DOM manipulation you intended if the val had changed. (never used lastText, lastResponseText, but that seems more elegant than placing it in a Form element. Is the above method violate any best practices? I'm trying to always pass JSON, and Ajax.PeriodicalUpdater does not allow that as far as I read. Always would like to hear other options myself) cheers, Mark On 6/9/07, Christophe Porteneuve <[EMAIL PROTECTED]> wrote: > > > Hey, > > Terry Riegel a écrit : > > Using I am using the Ajax.PeriodicalUpdater, and it is working great. > > How do I test to see if the content has changed from the last request? > > Well, why do you need to?
