// 找到所有的导航
var container = document.getElementById("container");
var as = container.getElementsByTagName("a");
// 找到所有内容
var oDivs = document.getElementsByClassName("content");
for(var i=0;i<as.length;i++){
给as设置index属性
as[i].setAttribute("index",i);
给as添加点击事件
as[i].onclick=function(){
先排除所有的
for(var j=0;j<as.length;j++){
as[j].className="";
oDivs[j].style.display="none";
}
再给自己加上
this.className="on";
var index=this.getAttribute("index");
oDivs[index].style.display="block";
}
}
