A Timer class to easily handle timing in JavaScript (based on AS3 Timer)
Use this class exactly like the ActionScript 3 Timer :
/* Instanciate a timer that loops 5 times every 1000 milliseconds
* (Setting the second argument to 0 will create an infinite timer)
*/
var timer = new Timer(1000, 5);
/*
* Add listeners to trigger on a Timer event
*/
function thing() {
doThings;
}
/* The method will be called 5 times, every second */
timer.addEventListener(Timer.Event.TIMER, function() {
doStuff;
});
/* thing() will be called once the 5 loops are complete */
timer.addEventListener(Timer.Event.TIMER_COMPLETE, thing);
timer.start(); // Start the timer
Like in AS3, you can stop(), or reset() the timer anytime you want.
Note that reset() will stop the timer if it is running.
You can remove the listeners by calling removeEventListener() :
/* thing() won't be called anymore */
timer.removeEventListener(Timer.Event.TIMER_COMPLETE, thing);
This can't be done with anonymous methods.
/* IMPOSSIBLE */
timer.removeEventListener(Timer.Event.TIMER, function() {
doStuff;
});
currentCount : int
[read-only] The total number of times the timer has fired since it started at zero.
running : Boolean
[read-only] The timer's current state; true if the timer is running, otherwise false.
Timer(delay, repeatCount)
Constructs a new Timer object with the specified delay and repeatCount states.
reset():void
Stops the timer, if it is running, and sets the currentCount property back to 0, like the reset button of a stopwatch.
start():void
Starts the timer, if it is not already running.
stop():void
Stops the timer.
complete():void
Calls all the listeners to the TIMER_COMPLETE event.
addEventListener(event, callback):void
Adds a listener to be triggered on a Timer event
removeEventListener(event, callback):void
Removes a previously added listener
getRepeatCount():int
Returns the total number of times the timer is set to run.
getDelay():int
Returns the delay, in milliseconds, between timer events.
getTimer():*
Returns the JavaScript setInterval() reference
getCallbacks():object
Returns an associative array containing the listeners for each event
setRepeatCount(value:int):void
Sets the total number of times the timer is set to run.
setDelay(value:int):void
Sets the delay, in milliseconds, between timer events.
Timer.Event.TIMER
Triggered on each loop
Timer.Event.TIMER_COMPLETE
Triggered at the end of the timer
