js代码：

// 根据类名获取li
var lis = document.getElementsByClassName("sna");
 
//循环遍历类名为sna的li标签
for(var i = 0;i<lis.length;i++){
 //为li注册鼠标移入事件
 lis[i].onmouseover = function(){
  /* this：类名为sna的li */
  //console.log(this);
  /* this.children：获取的li标签下的子元素 */
  // console.log(this.children);
  var next  = this.children;
  //next[1]:在li下的两个子元素中，需要显示出来的元素的标签的下标为1
  next[1].style.display = "block";
 };
 //为li注册鼠标移出事件
 lis[i].onmouseout = function(){
  var next  = this.children;
  next[1].style.display = "none";
 };
}
