[mootools] Class – CountDown Timer

mootoolsのClassでカウントダウンタイマー作ってみた。一時停止、リセット、再生、自動再生が出来る

Class

var CountDown = new Class({
	
	Implements:[Options,Events],
	
	options:{
		limit:60,
		onComplete:$empty
	},
	
	initialize:function(element,options){
		this.setOptions(options);
		this.element = element;
		this.limit = (this.options.limit * 1000);
		this.time = this.limit;
		this.cd = null;
		this.M = 0;
		this.S = 0;
		this.setter(this.limit);
		this.element.set("text",this.M+":"+this.S);
	},
	
	start:function(){
		this.cd=this.timer.periodical(1000,this);
	},
	
	pause:function(){
		$clear(this.cd);
	},
	
	reset:function(){
		$clear(this.cd);
		this.time = this.limit;
		this.setter(this.limit);
		this.element.set("text",this.M+":"+this.S);
	},
	
	setter:function(T){
		M = Math.floor(T/(60*1000));
		T = T-(M*60*1000);
		S = Math.floor(T/1000);
		
		if(S < 10) S = "0"+S;
		if(M < 10) M = "0"+M;
		
		this.S = S;
		this.M = M;
	},
	
	timer:function(){
		
		this.time = this.time - 1000;
		T = this.time;
		
		this.setter(T);
		
		this.element.set("text",this.M+":"+this.S);
		
		if(this.time==0){
			$clear(this.cd);
			this.fireEvent('complete');
		}
	}
});

<em>domready</em>

window.addEvent('domready', function(){
	var countdown = new CountDown($("time"),{
		limit:10,//time limit second
		onComplete:function(){$("time").set("text","Time Over");}
	});
	
	$("pause").addEvent("click",function(){
		countdown.pause();
	});
	
	$("start").addEvent("click",function(){
		countdown.start();
	});
	
	$("reset").addEvent("click",function(){
		countdown.reset();
	});
});

new CountDown(省略).start();にすると自動再生になる
