主要是你发图片别人不好调试
代码我自己觉得没有问题，但就是出不了结果
谢谢，你的代码可以出结果，你看看我的代码哪里出差错了
谢谢，你的代码可以出结果，你看看我的代码哪里出差错了
你代码错误很多，逻辑性错误就不说了，只说语法错误
var oTabNode = document.getElementById("goodlist");
var oCollUlNodes = oTabNode.getElementsByTagName("ul");
for(var x; x
if(oULNodes.className = "open"){ //比较相等用 “==” 。 oULNodes的l是小写
oUlNodes.className = "close";
}else{
oUlNodes.className = "open";
}
}else{
oCollUlNodes.className = "close"; //应该oCollUlNodes[x].className
}
