最近学dom写的一个小代码，本来是写扫雷的，也没写完，你看看，我现在就是点击li，显示li里的内容，运行一下就知道了
原理还是创建li的时候给它加上id
var newLi = document.createElement("li");
newLi.className = "li1";
newLi.id = "li" + (i*num + j);
然后取的时候根据id取就可以了
lis = document.getElementsByTagName("li");
for(i = 0 ; i < lis.length ; i++){
lis[i].onclick=function ss(){
liid = this.id;
num = parseInt(liid.substring(2));
if(temps[num] == -1){
alert("你踩到雷了");
}else{
alert(temps[num]);
}
}
}
