Hi,
Below is a patch to PeriodicalExecuter that should do what your
asking, I have Prototype 1.7.min and this patch is untested:
var
PeriodicalExecuter=Class.create({initialize:function(callback,frequency)
{this.callback=callback;this.frequency=frequency;this.currentlyExecuting=false;this.iterations=0;this.registerCallback()},registerCallback:function()
{this.timer=setInterval(this.onTimerEvent.bind(this),this.frequency*1000)},execute:function()
{this.callback(this)},stop:function(){if(!
this.timer)return;clearInterval(this.timer);this.timer=null},onTimerEvent:function()
{if(!this.currentlyExecuting)
{try{this.currentlyExecuting=true;this.iterations+
+;this.execute();this.currentlyExecuting=false}catch(e)
{this.currentlyExecuting=false;throw e}}}});
I suggest you make a backup of your current prototype implementation
if you have made any other modifications to it.
Replace the current PeriodicalExecuter class with the one above.
To find out what iteration PE is on just call 'pe.iterations', 'pe'
being the variable name of the argument supplied to the callback
function.
Or to find out from outside of the callback just use 'pe.iterations',
in this case 'pe' being the variable name in which the implementation
of PeriodicalExecuter is stored.
Hope this helps.
Cheers,
Chris
Oh and Merry Christmas.
