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+'">
