The example in this article describes how jQuery implements a very practical and beautiful select drop-down menu selection effect. Share it with everyone for your reference, the details are as follows:

First take a look at the following screenshots of the running effect:

The online demo address is as follows:

The specific code is as follows:

<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>实用漂亮的select下拉菜单</title>
<meta http-equiv="content-type" content="text/html;charset=gb2312">
<style type="text/css">
body{font-size:12px;}
.select{width:150px;height:24px;line-height:24px;position:relative;text-align:center;cursor:pointer;background:url(images/selectbg.jpg) right 0px no-repeat;color:#fff;}
.option{line-height:24px;width:150px;position:absolute;top:24px;left:0px;display:none;background:#820014;}
ul{list-style:none;margin:0;padding:0;}
ul li{height:24px;background:#666px;text-align:center;}
</style>
<script type="text/javascript" src="jquery1.3.2.js"></script>
<script type="text/javascript">
 $(document).ready(function(){
  var selects=$("#select");
  var options=$("#option");
  var state=true;
  selects.click(function(){
   if(state){
   if(!($(this).is(":animated"))){
    options.slideDown();
   }else{
    options.css("display","none");
  }  
   state=false;
   }else{
   if(!($(this).is(":animated"))){
   options.slideUp();
   }else{
    $(this).stop(true,true);
    options.css("display","");
   }
   state=true;
   }
  });
 selects.hover(function(){
 $(this).css("background","url(images/selectbg2.jpg) right 0px no-repeat");
 },
 function(){
 $(this).css("background","url(images/selectbg.jpg) right 0px no-repeat");
 });
  $("li").hover(function(){
   $(this).css("background","#990000").css("color","#ff9900");
  },
  function(){
   $(this).css("background","#820014").css("color","#fff");
  });
  $("li").click(function(){
   $(this).css("background","#c00").css("color","#ffffff");
   options.css("display","none");
   selects.children("span").text($(this).attr("tip"));
   $(".valt").val($(this).attr("tip"));
   state=false;
  });
  options.click(function(){
   selects.click(function(){return false;});
  });
 })
</script>
</head>
<body>
预览效果时左下角会提示错误，而且看不到效果，刷新一下就可以看到效果了；当然，在实际使用中，不会出现这样的问题。<br>
您的选择是：<input type="text" class="valt" value="">
<div class="select" id="select"><span>请选择分类</span>
 <div class="option" id="option">
  <ul>
   <li tip="推荐课程">推荐课程</li>
   <li tip="资讯中心">资讯中心</li>
   <li tip="辅导专区">辅导专区</li>
