我正在建立一个二十一主题的wordpress网站。我想要一个小部件区域只显示在某个页面上。
所以在由<head>
<body onload="show_collection_area">添加了一个javascript函数
调用该函数，因为console.log（obj.id）将“text-2”写入控制台（这是正确的id）。但是当我在这个函数中将visibilty设置为none时
function show_collection_area(){
if (document.location == "http://dutchmountaineer.com/wp/?page_id=116"){
obj = document.getElementById('text-2');
obj.style.visibility = 'visible';
console.log(obj.id)
console.log(obj);
} else {
document.getElementById("text-2").style.visibility = 'none';
}
}
没有发生。我尝试使用按钮从页面本身调用该函数，但结果是相同的。
我做错了什么？
非常感谢！
PS整个代码：

当您希望隐藏“可见性”时，“隐藏”值应为“隐藏”。 “none”值适用于“display”。
