 var lis = document.querySelectorAll("li"); 
 var imgs = document.querySelectorAll("img"); 
 for(var i = 0; i < lis.length; i++) { 
 //给所有的li标签添加点击事件 
 lis[i].onclick = function () { 
  //将所有的图片宽度设置为0 
  for(var i = 0; i < lis.length; i++) { 
  imgs[i].style.width = "0px"; 
  } 
  //将当前点击li标签中的img标签设置宽度为220px 
  this.querySelector("img").style.width = "220px"; 
 }
