这年头，不管你用什么语言搞开发，都得搞个星星评价的功能。因为这个星星评价既美观又实用，搞起来还费不了多大的事，因此很多人都在用，很多人都在搞。如今，因项目需要用Dojo开发一个星星评价功能，于是乎俺就搞了这么一个。具体实现如下：

　　1、素材准备，1个灰色星星，1个金色星星。

　　2、使用HTML绘制出五个星星，Code如下：

.ecmEvaluation{
	
}

.ecmEvaluation .commentscore{
	margin-top:5px;
	margin-bottom:3px;
}

.ecmEvaluation .startOnClass{
	background-image: url("images/star-on.gif");
	background-repeat: no-repeat;
	text-align: center;
	width: 20px;
	height: 20px;
	display: inline-block;
}

.ecmEvaluation .startOffClass{
	background-image: url("images/star-off.gif");
	background-repeat: no-repeat;
	text-align: center;
	width: 20px;
	height: 20px;
	display: inline-block;
}

.ecmEvaluation .reteTxtClass{
	vertical-align: 5px;
}

.ecmEvaluation .commentContent{
	height:100px;
}

initUI: function(){
	dojo.removeClass(this.rate1.children[0],"startOffClass");
	dojo.addClass(this.rate1.children[0],"startOnClass");
	for(var i=2; i<=5; i++){
		var rate = "rate"+i;
		dojo.removeClass(this[rate].children[0],"startOnClass");
		dojo.addClass(this[rate].children[0],"startOffClass");
	}
	this.score = 1;
	this.rateTxt.innerHTML ="1分";
},//鼠标滑过时的效果
_onHover: function(event){
	this.logger.debug("_onHover");
	if(this.rate1 == event.currentTarget){
		dojo.removeClass(this.rate1.children[0],"startOffClass");
		dojo.addClass(this.rate1.children[0],"startOnClass");
		for(var i=2; i<=5; i++){
			var rate = "rate"+i;
    		dojo.removeClass(this[rate].children[0],"startOnClass");
    		dojo.addClass(this[rate].children[0],"startOffClass");
		}
		this.score = 1;
		this.rateTxt.innerHTML ="1分";
	}else if(this.rate2 == event.currentTarget){
		for(var i=1; i<=2; i++){
			var rate = "rate"+i;
    		dojo.removeClass(this[rate].children[0],"startOffClass");
    		dojo.addClass(this[rate].children[0],"startOnClass");
		}
		for(var i=3; i<=5; i++){
			var rate = "rate"+i;
    		dojo.removeClass(this[rate].children[0],"startOffClass");
		}
		this.score = 2;
		this.rateTxt.innerHTML ="2分";
	}else if(this.rate3 == event.currentTarget){
		for(var i=1; i<=3; i++){
			var rate = "rate"+i;
    		dojo.removeClass(this[rate].children[0],"startOnClass");
		}
		for(var i=4; i<=5; i++){
			var rate = "rate"+i;
    		dojo.removeClass(this[rate].children[0],"startOffClass");
		}
		this.score = 3;
		this.rateTxt.innerHTML ="3分";
	}else if(this.rate4 == event.currentTarget){
		for(var i=1; i<=4; i++){
			var rate = "rate"+i;
    		dojo.removeClass(this[rate].children[0],"startOnClass");
		}
		for(var i=5; i<=5; i++){
			var rate = "rate"+i;
    		dojo.removeClass(this[rate].children[0],"startOffClass");
		}
		this.score = 4;
		this.rateTxt.innerHTML ="4分";
	}else if(this.rate5 == event.currentTarget){
		for(var i=1; i<=5; i++){
			var rate = "rate"+i;
    		dojo.removeClass(this[rate].children[0],"startOnClass");
		}
		this.score = 5;
		this.rateTxt.innerHTML ="5分";
	}
