Rails spinoffs - Oct 2007 - proposal for an extension to Ajax.PeriodicalUpdater stop();

Hi,

lately i used Ajax.PeriodicalUpdater in a project to keep fetching an
pageable ajax object from my backend and i ran into a small problem.

whenever the user pressed the button to page through the list i have
to stop the periodicalupdater to not overwrite my divbox, which was
rather trivial, however - once the user paged back to the first page
the updater should be started again.

now my solution was - put a javascript into the html if its the first
page and kickstart the updater from there but that lead to a infinite
loop, so i had to supply the updater object with a boolean stopped
property whenever i started and stopped it, that would then be checked
by the embeded javascript in the html of the ajax response.

how about the periodical updater class setting this stopped property
itself which would make it easier to check if the updater is running
or not?

something like this:

@ Line 1122 in prototype.js

start: function() {
    this.options.onComplete = this.updateComplete.bind(this);
    this.stopped = false;
    this.onTimerEvent();
  },

  stop: function() {
    this.updater.options.onComplete = undefined;
    clearTimeout(this.timer);
    this.stopped = true;
    (this.onComplete || Prototype.emptyFunction).apply(this,
arguments);
  },
