var PeriodicalExecuter = Class.create({
initialize: function(callback, frequency) {
this.callback = callback;
this.frequency = frequency;
this.currentlyExecuting = false;
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.execute();
this.currentlyExecuting = false;
} catch(e) {
this.currentlyExecuting = false;
throw e;
}
}
}
});
這是 prototype 的 函式
看起來好像沒辦法停止.....還是直接把 PeriodicalExecuter 物件delect 掉
這樣還會跑嗎???
