jquery星级评分
前面有一篇原生js实现星级评分 。可能覆盖面不是很广,现在给出一个jquery实现的星级评分
- <divclass="star">
- <span>jQuery星级评论打分</span>
- <ul>
- <li><ahref="javascript:;">1</a></li>
- <li><ahref="javascript:;">2</a></li>
- <li><ahref="javascript:;">3</a></li>
- <li><ahref="javascript:;">4</a></li>
- <li><ahref="javascript:;">5</a></li>
- </ul>
- </div>
<div class="star"> <span>jQuery星级评论打分</span> <ul> <li><a href="javascript:;">1</a></li> <li><a href="javascript:;">2</a></li> <li><a href="javascript:;">3</a></li> <li><a href="javascript:;">4</a></li> <li><a href="javascript:;">5</a></li> </ul> </div>
- <style>
- *{margin:0;padding:0;font-size:13px;}
- ul,li{list-style:none;}
- .star {position:relative;width:600px;height:24px; margin:20px auto 0;}
- .star span {float:left;height:19px;line-height:19px;}
- .star ul{margin:0 10px;}
- .star li{float:left;width:24px;height:22px;text-indent:-9999px;background:url('star.png') no-repeat;cursor:pointer;}
- .star li.on{background-position:0 -28px;}
- .star p {padding:10px 10px 0;position:absolute;top:20px;width:159px;height:60px;z-index:100;}
- .star p em {color: #FF6600;display: block;font-style: normal;}
- .star strong {color:#ff6600;padding-left:10px;}
- .hidden{display:none;}
- </style>
<style> *{margin:0;padding:0;font-size:13px;} ul,li{list-style:none;} .star {position:relative;width:600px;height:24px; margin:20px auto 0;} .star span {float:left;height:19px;line-height:19px;} .star ul{margin:0 10px;} .star li{float:left;width:24px;height:22px;text-indent:-9999px;background:url('star.png') no-repeat;cursor:pointer;} .star li.on{background-position:0 -28px;} .star p {padding:10px 10px 0;position:absolute;top:20px;width:159px;height:60px;z-index:100;} .star p em {color: #FF6600;display: block;font-style: normal;} .star strong {color:#ff6600;padding-left:10px;} .hidden{display:none;} </style>

这个也是在网上找的一个相对自己来说更实用一点的。做储备。
