用层（DIV)来实现弹出窗口

现在网上有很的软件用来阻止网页中的弹出窗口，本来倒是好事，用户可以根据需要来阻止那些广告什么的。但有很多这种小软件是流氓软件，不知不觉中这装上去了，很多人还装了很多，但又不会设置。这就要我们程序员，来很办法避开这些软件，让用户看到我们所要展示的内容。用户层来模拟弹出窗口，是个不错的选择。
如下图所示：

上面的客户信息窗体就是通过层模拟出来的。
下面是源代码：
windemo.html

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" >

<HTML>

<HEAD>

<title>windemo1</title>

</script>

</HEAD>

<body>

<A onclick="if (winList['sample2']) winList['sample2'].open('table.aspx'); return false;"

href="#">客户信息列表</A>

<AREA title="Minimize" onclick="this.parentWindow.minimize();return false;" shape="RECT"

alt="最小化" coords="0,0,15,13">

<AREA title="Restore" onclick="this.parentWindow.restore();return false;" shape="RECT"

alt="还原" coords="16,0,31,13">

<AREA title="Close" onclick="this.parentWindow.close();return false;" shape="RECT" alt="关闭"

coords="34,0,49,13">

</MAP>

</DIV>

</iframe>

</DIV>

</form>

</body>

</HTML>

可以修改<div class="clientArea"></div>中的内容，去掉<iframe>标记，直接添加显示内容，在调用onclick，打开窗体时，用open()，不带参数。
