<script type="text/javascript">$(function(){ //简洁用户评分代码 $(".pfxtFen li").click(function(){ $(this).addClass("pfxtCur"); $(this).prevAll().addClass("pfxtCur"); $(this).nextAll().removeClass("pfxtCur"); });  $(".pfxtFen li").dblclick(function(){ $(".pfxtFen li").removeClass("pfxtCur"); }); })</script>

<style type="text/css">*{margin:0;padding:0; font-family:"微软雅黑"}ul{ list-style:none;} /*用户评分*/.pingfenxitong{ padding:15px 0; width:500px; margin:0 auto; }.pingfenList{ float:left; width:500px; padding-right:20px; }.pfxtTitle{ font-weight:bold; font-size:1.2em; padding:4px 0; }.pfxtText{ line-height:25px; }.pfxtFen{ margin:10px 0; }.pfxtFen li{ float:left; width:98px; height:30px; text-align:center; line-height:30px; border:#ddd 1px solid; background:#f1f1f1; cursor:pointer; }.pfxtFen li.pfxtCur{ background:#308A95; color:#fff; border:#308A95 1px solid; }</style>
