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";
