addEventListener and function parameters

[astralaaron]

hi I am trying to understand why the following:function placeIt(thenum){ trace("number is: " + thenum);}EXAMPLE 1:-------var thenumber:int = 2;timer.addEventListener(TimerEvent.TIMER, function(){ placeIt(thenumber) });--------------------EXAMPLE 2:-------timer.addEventListener(TimerEvent.TIMER, function(){ placeIt(2) });--------------------does anyone understand why in example 1 that the parameter doesn't pass through? the trace outputs "number is: 0"but in example 2 trace outputs "number is: 2"

Is the value of that variable changing anywhere? It looks like it's changing, otherwise the output would be undefined instead of 0.

my only guess is that the context within addEventListener is the object's context, so it can only find object methods and properties. Since thenumber isnt a class property, it cant find it. Im having weird issues with the addEventListener method myself, coming from regular JavaScript.

yeah, actually it will be like this private function test():void { var thenumber:int = 2; timer.addEventListener(TimerEvent.TIMER, nonamed);} private function nonamed():void { placeIt(thenumber); // now thenumber is unknown}
