Question

$.PeriodicalUpdater.stop();

…gives me…

TypeError: Result of expression '$.PeriodicalUpdater.stop' [undefined] is not a function.

I’ve checked an double checked the owner’s manual, I cannot figure out why this isn’t working correctly. The error is harmless for the most part, it’s just the user’s browser won’t stop making server calls that it no longer needs.

Thanks!

Answer 1

The doc says

The function call returns a handle. You can call .stop() on this
handle in order to stop the updating and ignore any subsequent
responses. If the maximum number of calls, .stop(), or the autoStop
has been triggered, you can restart the updater using .restart() on
the handle. This handle is also passed into the callback function as
the fourth argument.

so it should be

var handle =$.PeriodicalUpdater(url, options);
handle.stop();

EDIT – after your comments, try

$.PeriodicalUpdater( url, { options, function(remoteData, success, xhr, handle){ 
  if(condition){ 
     handle.stop(); 
   } 
});
