仿淘宝星级评分效果

2010-9-3 作者:yunsudong 来源:51js 投递文章

最近一个小项目需要一个星级评分的效果,所以去淘宝偷了一个,但是还得加载YUI很不爽,还是自己动手写一个吧~


HTML:

 

<!--
    # 星级评分
    # star:value = 分数
-->
<div class="shop-rating">
    <span class="title">物流公司的服务:</span>
    <ul class="rating-level" id="stars2">
        <li><a class="one-star" star:value="20" href="#">20</a></li>
        <li><a class="two-stars" star:value="40" href="#">40</a></li>
        <li><a class="three-stars" star:value="60" href="#">60</a></li>
        <li><a class="four-stars" star:value="80" href="#">80</a></li>
        <li><a class="five-stars" star:value="100" href="#">100</a></li>
    </ul>
    <span class="result" id="stars2-tips"></span>
    <input type="hidden" id="stars2-input" name="b" value="" size="2" />
</div>
<!-- END 星级评分 -->

CSS:

.rating-level .three-stars .current-rating,.rating-level .four-stars .current-rating,.rating-level .five-stars .current-rating{background-position:0 -28px;}

结构和样式是偷淘宝的!!


JS:

 

var Class = {
    create: function() {
        return function() { this.initialize.apply(this, arguments); }
    }
}
var Extend = function(destination, source) {
    for (var property in source) {
        destination[property] = source[property];
    }
}
function stopDefault( e ) {
     if ( e && e.preventDefault ){
        e.preventDefault();
    }else{
        window.event.returnValue = false;
    }
    return false;
}
/**

var Stars = Class.create();
Stars.prototype = {
    initialize: function(star,options) {
        this.SetOptions(options); //默认属性
        var flag = 999; //定义全局指针
        var isIE = (document.all) ? true : false; //IE?
        var starlist = document.getElementById(star).getElementsByTagName('a'); //星星列表
        var input = document.getElementById(this.options.Input) || document.getElementById(star+"-input"); // 输出结果
        var tips = document.getElementById(this.options.Tips) || document.getElementById(star+"-tips"); // 打印提示
        var nowClass = " " + this.options.nowClass; // 定义选中星星样式名
        var tipsTxt = this.options.tipsTxt; // 定义提示文案
        var len = starlist.length; //星星数量
        
        for(i=0;i<len;i++){ // 绑定事件 点击 鼠标滑过
            starlist[i].value = i;
            starlist[i].onclick = function(e){
                stopDefault(e);
                this.className = this.className + nowClass;
                flag = this.value;
                input.value = this.getAttribute("star:value");
                tips.innerHTML = tipsTxt[this.value]
            }
            starlist[i].onmouseover = function(){
                if (flag< 999){
                    var reg = RegExp(nowClass,"g");
                    starlist[flag].className = starlist[flag].className.replace(reg,"")
                }
            }
            starlist[i].onmouseout = function(){
                if (flag< 999){
                    starlist[flag].className = starlist[flag].className + nowClass;
                }
            }
        };
        if (isIE){ //FIX IE下样式错误
            var li = document.getElementById(star).getElementsByTagName('li');
            for (var i = 0, len = li.length; i < len; i++) {
                var c = li[i];
                if (c) {
                    c.className = c.getElementsByTagName('a')[0].className;
                }
            }
        }
    },
    //设置默认属性
    SetOptions: function(options) {
        this.options = {//默认值
            Input:            "",//设置触保存分数的INPUT
            Tips:            "",//设置提示文案容器
            nowClass:    "current-rating",//选中的样式名
            tipsTxt:        ["1分-严重不合格","2分-不合格","3分-合格","4分-优秀","5分-完美"]//提示文案
        };
        Extend(this.options, options || {});
    }
