在HTML中用JavaScript实现一个层的隐藏和显示（button控件）小问题？

YangBHMing 2011-05-16 11:58:36

我的代码是这样的：

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312" />
<title>无标题文档</title>
</head>
<script>
function ok1()
{
var a=document.getElementById("div1");
if(a.style.display=="none")
a.style.display="block";
else
a.style.display="none";
}
</script>

<body>

<a href="#" onmouseout="ok1();" onmouseover="ok1();">显示层</a>
<input type="button" value="显示/隐藏" onclick="ok1();" >
<br>
<div id="div1" style="display:none;background-color:yellow;width:100px;height:100px;border-style:solid;border-

color:red;border-width:1px"><Br>点一下隐藏</div>
</body>
</html>

我想大家看了代码就知道效果了，就是简单的层的隐藏和显示，但我有一个问题
我这个效果是点击button按钮下面的层显示出来，再点击下按钮层就隐藏。这不是我要的效果
我想在我点击button按钮的时候层显示出来。我鼠标点击页面别的空白处层就隐藏。请教事件或是方法。先谢谢了

也可以增加一个透明的遮罩层，位于显示层和页面之间，点击遮罩层时，将这两个层隐藏掉

类似于相册查看时的那种效果

我下面的代码只能在ie下有效,

由于在ff下div无法focus,所以在ff下,下面代码无效.

等待能够兼容ff的代码!!!!
