的getElementById没有得到ID在WordPress 3.3.1

-1

我建立一个WordPress站点，二十11的主题。我想要一个小部件区域只显示在某个页面上。的getElementById没有得到ID在WordPress 3.3.1

所以加入JavaScript函数到<head>其通过<body onload="show_collection_area">

该函数调用叫，由于执行console.log（obj.id）写道：“文本-2”到控制台（这是正确的ID ）。但是当我在这个功能中设置visibilty为none：

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函数，但结果相同。

我在做什么错了？

非常感谢！

PS整个代码：

你做错的第一件事就是出一大堆PHP的时候你的问题是关于如何JS，CSS和HTML与相互影响。 – Quentin 2012-02-15 13:51:13

对不起，这是你做错的第二件事。你做错的第一件事就是使用客户端JS来确定在页面上显示的内容，而不是在PHP中执行。 – Quentin 2012-02-15 13:52:17

第二个代码块将在必要时提供上下文。事先不知道是否有人会要求。如果您的意见不具有建设性，请不要在将来发布它们。谢谢 – jorrebor 2012-02-15 14:03:55

的“知名度”应为“隐藏”，当你希望它被隐藏的价值。 “无”值适用于“显示”。
