点击文字或按钮弹出一个DIV窗口（DIV悬浮窗口）
以下是弹出窗口代码：
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>点击文字弹出一个DIV层窗口代码</title>
<style>
.black_overlay{
display: none;
position: absolute;
top: 0%;
left: 0%;
width: 100%;
height: 100%;
background-color: black;
z-index:1001;
-moz-opacity: 0.8;
opacity:.80;
filter: alpha(opacity=88);
}
.white_content {
display: none;
position: absolute;
top: 25%;
left: 25%;
width: 55%;
height: 55%;
padding: 20px;
border: 10px solid orange;
background-color: white;

}
</style>
</head>
<body>
<p>示例弹出层：<a href = "javascript:void(0)" onclick = "document.getElementById('light').style.display='block';document.getElementById('fade').style.display='block'">请点这里</a></p>
<div id="light" class="white_content">这是一个层窗口示例程序.
<a href = "javascript:void(0)" onclick = "document.getElementById('light').style.display='none';document.getElementById('fade').style.display='none'">点这里关闭本窗口</a></div>
<div id="fade" class="black_overlay"></div>
</body>
</html>上面的为点击汉字链接，打开DIV窗口
下面的是我改过的，CSS样式没有改。
<div id="fileOperation" class="white_content">
<div id="fade" class="black_overlay">
<a href = "javascript:void(0)" onclick = "document.getElementById('fileOperation').style.display='none';document.getElementById('fade').style.display='none'">
<input type="button" style="float:right" value="关闭"/>
</a></div>
<p style="margin:0 0 5px 0 ;float:right"><a style="margin:0 0 5px 0 ;float:right" href = "javascript:void(0)" onclick = "document.getElementById('fileOperation').style.display='block';document.getElementById('fade').style.display='block'">
<button style="margin:0 0 5px 0 ;float:right" onclick="information()">文件操作记录</button>
</a>
</p>
