通过WMI来实现获取客户端计算机硬件及系统信息:
1//系统信息获取
2function getSysInfo(){
3 var locator = new ActiveXObject ("WbemScripting.SWbemLocator");
4 var service = locator.ConnectServer(".");
5 //CPU信息
6 var cpu = new Enumerator (service.ExecQuery("SELECT * from Win32_Processor")).item();
7 var cpuType=cpu.Name,hostName=cpu.SystemName;
8 //内存信息
9 var memory = new Enumerator (service.ExecQuery("SELECT * from Win32_PhysicalMemory"));
10 for (var mem=[],i=0; !memory.atEnd(); memory.moveNext()) mem[i++]={cap:memory.item().Capacity/1024/1024,speed:memory.item().Speed}
11 //系统信息
12 var system=new Enumerator (service.ExecQuery("SELECT * from Win32_ComputerSystem")).item();
13 var physicMenCap=Math.ceil(system.TotalPhysicalMemory/1024/1024),curUser=system.UserName,cpuCount=system.NumberOfProcessors
14
15 return {cpuType:cpuType,cpuCount:cpuCount,hostName:hostName,curUser:curUser,memCap:physicMenCap,mem:mem}
16}
代码实现主要包括这几部分：
先通过new ActiveXObject ( ......

var xmlDoc;
function cleanData(getObj)
{
if(getObj)
{
getObj.options.length = 0;
}
}

Every Web developer has to tangle with tables. A new open source library, DisplayTag, can make life with tables much more organized. Find out how to combine the DisplayTag library with JavaScript to make a slick app that displays line item details.  
by Stephen Strenn
isplaying data in a table is everyday work for Web application developers. In this 10-minute solution, you will learn how to quickly create feature-rich tables for your JSP pages using the DisplayTag library and a little JavaScript. Specifically, the table features that we want include:
Alternating row colors
Column sorting and formatting
Row-grouping with subtotals for selected columns
Page navigation
Export to XML, Excel, PDF, and CSV
Support for standard JSP and the Expression Language (EL)
Row interactivity—a row is highlighted as the mouse passes over it, and if the user clicks anywhere on the row, a new request is generated that includes a parameter indicating which row was clicked.

WPF的WebBrowser和WinForm的WebBrowser有一定区别。
要向其中注入javascript脚本，经过本人试验，下面一条路可以走通：
 mshtml.HTMLDocument htmlDoc = Browser.Document as mshtml.HTMLDocument;
var head = htmlDoc.getElementsByTagName("head").Cast<HTMLHeadElement>().First();
var script = (IHTMLScriptElement)htmlDoc.createElement("script");
script.text = "alert('hello world')";
head.appendChild((IHTMLDOMNode)script);
该方法还可以注入javascript函数，在需要的时候调用 Browser.InvokeScript()即可。
但是今天发现一个很奇怪问题。。我用该注入方法修改 document.body.style.zoom，整个页面会缩放，但是其中的flash等控件居然有问题。。
然后我用IE8带的开发人员工具注入修改 document.body.style.zoom 则没这个问题。。。
太奇怪了，改天继续研究。 ......

1、运算符++为累加，若x=5，y=++x，则y=6；运算符- -为递减，若x=5，y=--x,则y=4
2、条件运算符：greeting=(visitor= =”PRES”)?”Dear President”:”Dear”;
如果变量visitor中的值是“PRES”，则向变量greeting赋值“Dear President”,否则赋值“Dear”
3、可以用以下方法得到浏览器时间：
Var d = new Data()
Var time = d.getHours()
TheDay = d.getDay()         得到星期几
4、javascript switch 语句
  Switch (n)
{
case 1;
执行代码块1
break
case 2:
执行代码块2
break
default:
    如果n既不是也不是2，则执行此代码
}
5、javascript的三种消息框：警告框(alert)、确认框(confirm)、提示框(prompt)
警告框的用法：
<html>
<head>
<script type="text/javascript">
function disp_alert()
{
alert("再次向您问好！在这里，我们向您演示" + '\n' + "如何向警告框添加折行。")
}
</script>
</head>
<body>
 
<input type="button" onclick="disp_alert() ......
