getElementsByTagName是多个的所以要加下标
window.onload = function(){
Li = document.getElementsByTagName("div")[0].getElementsByTagName("li");
LiLength = Li.length;
for(let i=0;i<LiLength;i++){
Li[i].index = i;
Li[i].onclick = function(){
var index = this.index;
alert(index);
};
}
}
window.onload = function(){
Li = document.getElementsByTagName("div")[0].getElementsByTagName("li");
LiLength = Li.length;
for(let i=0;i<LiLength;i++){
Li[i].index = i;
Li[i].onclick = function(){
var index = this.index;
alert(index);
};
}
}
