实现方法:
1.html引用star-grade.js
<script type="text/javascript" src="Scripts/star-grade.js"></script> <script type="text/javascript"> $(document).ready(function () { $(".sstar").BindStars();//使用属性data-score获取评分值 $("#pye").SetStars(3);//传分数,自动列出星星 }); </script>
<body> <div class="starscore sstar"> <i></i> <i></i> <i></i> <i></i> <i></i> </div> <span id="ye"></span> <div class="starscore" id="pye"></div> <div class="starscore starscore_sm" > <i class="inred"></i> <i class="inred"></i> <i></i> <i></i> <i></i> </div> <div class="starscore starscore_lg"> <i class="onred"></i> <i class="onred"></i> <i></i> <i></i> <i></i> </div> </body>
2.css样式
@charset "utf-8"; /* CSS Document */ .starscore { width: 200px; height: 30px; } .starscore i { width: 14px; height: 14px; background: url(images/gray.gif) no-repeat; /* 14x14的灰色星星图标 */ display: inline-block; vertical-align: middle; background-size: contain; } .starscore i.inred, .starscore i.onred { background: url(images/yel.gif) no-repeat; /* 14x14的黄色星星图标 */ } .starscore_lg > i { width: 18px; height: 18px; } .starscore_sm > i { width: 12px; height: 12px; }
3.插件js源码
/* * jq扩展--星星评分插件 * * 通过对象的属性data-score获取评分值 * 星星使用元素i表示,绑定星星背景图 * 鼠标进入、离开事件的绑定样式为inred,改变背景图 * 点击事件的绑定样式为onred,改变背景图 */ (function ($) { "use strict"; $.fn.BindStars = function () { var starElement = $(this); starElement.children("i").mouseleave(function () { starElement.find("i").each(function (index) { $(this).removeClass("inred"); }); }); starElement.children("i").mouseenter(function () { var curIndex = starElement.find("i").index(this); starElement.find("i").each(function (index) { if (index <= curIndex) { $(this).addClass("inred"); } else { $(this).removeClass("inred"); } }); }); starElement.children("i").click(function () { var curIndex = starElement.find("i").index(this); starElement.find("i").each(function (index) { if (index <= curIndex) { $(this).addClass("onred"); } else { $(this).removeClass("onred"); } }); starElement.attr("data-score", curIndex + 1); }); }; $.fn.SetStars = function (score) { var scoreStr = ""; for (var i = 0; i < 5; i++) { if (i < score) { scoreStr += "<i class=‘onred‘></i>"; } else { scoreStr += "<i></i>"; } } $(this).html(scoreStr); }; })(window.jQuery);
