  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <link rel="stylesheet" href="index.css">

<body>
  <div class="wrapper">
    <div class="search">
      <input type="text" placeholder="请输入用户名">//搜索框
      <p>//性别筛选按钮
        <span sex='m'>male</span>
        <span sex='f'>female</span>
        <span sex='a' class="active">all</span>
      </p>
    </div>
    <div class="user-list">//搜索列表，有js渲染添加
      <ul>
      </ul>
    </div>
  </div>
  <script src="/UploadFiles/2021-04-02/index.js">

CSS代码：


*{
  margin:0;
  padding:0;
  list-style: none;
}
.wrapper{
  width:400px;
  border:1px solid #ccc;
  margin: 100px auto;
  border-radius:4px;
}
.wrapper .search{
  width:100%;
  height:50px;
  line-height:50px;
}
.wrapper .search input{
  padding:10px 15px;
  border-radius:4px;
  margin-left:30px;
  border:1px solid #ccc;
  outline:none;

}
.wrapper .search p{
  display:inline-block;
}
.wrapper .search p span{
  color:#38f;
  padding:3px 5px;
}
.wrapper .search p span.active{
  color:#fff;
  background-color:#38f;
  border-radius: 4px;
}
.wrapper .user-list{
  width:100%;
}
.wrapper .user-list ul{
  width:100%;
}
.wrapper .user-list ul li{
  border-bottom:1px solid #ccc;
  position:relative;
  padding:10px 0;
  margin:0 30px;
}
.wrapper .user-list ul li img{
  height:40px;
  width:40px;
  position:absolute;
}
.wrapper .user-list ul li p{
  margin-left:50px;
  width:300px;
  color:rgb(117, 114, 114);
}



Javascript代码：


var oul=document.getElementsByTagName("ul")[0];
var oinput=document.getElementsByTagName("input")[0];
var text='',sex='a';//要将text和sex写在全局变量里面，这样可以记录上次操作的值为后续的页面渲染作准备；
var personArr=[
  {name:'王刚',src:'images/1.png',des:'颈椎不好',sex:'m'},
  {name:'刘颖',src:'images/2.png',des:'我是谁',sex:'f'},
  {name:'王秀英',src:'images/3.jpg',des:'我很好看',sex:'f'},
  {name:'刘金磊',src:'images/4.png',des:'你没有见过陌生人的脸',sex:'m'},
  {name:'刘飞仙',src:'images/5.jpg',des:'瓜皮刘',sex:'m'}
];
//页面渲染
function randerlist(arr){
  var str='';
  arr.forEach(function(elem,index){
    str+='<li>    <img src="/UploadFiles/2021-04-02/'+elem.src+'">
