一.【使用html将silverlight添加到网页】

当我新建立一个silverlight 项目的时候，我们会在.web项目当中发现对应 silverlight应用程序名称的.html 我们打开发现他是如下结构的

![ContractedBlock.gif][] ![ExpandedBlockStart.gif][] 代码

<! 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 >   
 < title > MySilverlightDemo </ title >   
 < style  type ="text/css" >   
html, body  
 \{    
height :  100% ;   
overflow :  auto ;   
 \}   
body  
 \{    
padding :  0 ;   
margin :  0 ;   
 \}   
\#silverlightControlHost  
 \{    
height :  100% ;   
text-align :  center ;   
 \}   
 </ style >   
  
 < script  type ="text/javascript"  src ="Silverlight.js" ></ script >   
  
 < script  type ="text/javascript" >   
  
 function  onSilverlightError(sender, args) \{  
 var  appSource  =  "" ;  
 if  (sender  !=  null  &  sender  !=  0 ) \{  
appSource  =  sender.getHost().Source;  
\}  
  
 var  errorType  =  args.ErrorType;  
 var  iErrorCode  =  args.ErrorCode;  
  
 if  (errorType  ==  " ImageError "  ||  errorType  ==  " MediaError " ) \{  
 return ;  
\}  
  
 var  errMsg  =  " Silverlight 应用程序中未处理的错误 "  \+  appSource  \+  " \\n " ;  
  
errMsg  \+=  " 代码:  "  \+  iErrorCode  \+  "  \\n " ;  
errMsg  \+=  " 类别:  "  \+  errorType  \+  "  \\n " ;  
errMsg  \+=  " 消息:  "  \+  args.ErrorMessage  \+  "  \\n " ;  
  
 if  (errorType  ==  " ParserError " ) \{  
errMsg  \+=  " 文件:  "  \+  args.xamlFile  \+  "  \\n " ;  
errMsg  \+=  " 行:  "  \+  args.lineNumber  \+  "  \\n " ;  
errMsg  \+=  " 位置:  "  \+  args.charPosition  \+  "  \\n " ;  
\}  
 else  if  (errorType  ==  " RuntimeError " ) \{  
 if  (args.lineNumber  !=  0 ) \{  
errMsg  \+=  " 行:  "  \+  args.lineNumber  \+  "  \\n " ;  
errMsg  \+=  " 位置:  "  \+  args.charPosition  \+  "  \\n " ;  
\}  
errMsg  \+=  " 方法名称:  "  \+  args.methodName  \+  "  \\n " ;  
\}  
  
 throw  new  Error(errMsg);  
\}  
  
 function  onSourceDownloadProgressChanged(sender, eventArgs) \{  
  
sender.findName( " uxStatus " ).SetValue( " Foreground " ,  " White " );  
sender.findName( " uxStatus " ).Text  =  " Loading:  "  \+  Math.round((eventArgs.progress  \*  1000 ))  /  10  \+  " % " ;  
sender.findName( " uxProgressBar " ).ScaleY  =  eventArgs.progress  \*  356 ;  
\}  
  
  
 </ script >   
  
 </ head >   
 < body >   
 < div  id ="silverlightControlHost" >   
 < object  data ="data:application/x-silverlight-2,"  type ="application/x-silverlight-2" width ="100%"  height ="100%" >   
 < param  name ="source"  value ="ClientBin/MySilverlightDemo.xap"  />   
 < param  name ="onerror"  value ="onSilverlightError"  />   
 < param  name ="background"  value ="white"  />   
 < param  name ="minRuntimeVersion"  value ="3.0.40818.0"  />   
 < param  name ="autoUpgrade"  value ="true"  />   
 < param  name ="splashscreensource"  value ="SplashScreen.xaml"  />   
 < param  name ="onSourceDownloadProgressChanged"  value ="onSourceDownloadProgressChanged"  />   
 < a  href ="http://go.microsoft.com/fwlink/?LinkID=149156&v=3.0.40818.0"  style ="text-decoration: none;" >   
 < img  src ="http://go.microsoft.com/fwlink/?LinkId=108181"  alt ="获取 Microsoft Silverlight"   
style ="border-style: none"  />   
 </ a >   
 </ object >   
 < iframe  id ="\_sl\_historyFrame"  style ='visibility:  hidden; height: 0; width: 0; border: 0px' >   
 </ iframe >   
 </ div >   
 </ body >   
 </ html >

我们可以清晰的看到，这里面有有脚本，哪个能帮助我们家在silverlight程序呢，就是通过这个object对象来实现的。

二.【使用javascript将silverlight 嵌入到网页当中】

![ContractedBlock.gif][] ![ExpandedBlockStart.gif][] 代码

< script type = " text/javascript " >   
Silverlight.createObject(  
 " ClientBin/SilverlightApplication1.xap " ,  //  source   
  silverlightControlHost,  //  parent element   
  " slPlugin " ,  //  id for generated object element   
  \{  
width:  " 100% " , height:  " 100% " , background:  " white " ,  
version: " 3.0.40620.0 "   
\},  
\{ onError: onSLError, onLoad: onSLLoad \},  
 " param1=value1,param2=value2 " ,  
 " context "  //  context helper for onLoad handler.   
  );  
 < / script>

我就不太喜欢用这种方式，主要是js水平有限啊，再加上提示少.

三.【指定和检索自定义参数】

这个可是很重要的，不过也很简单。

在承载页面<object>下面加上 <param name="initParams" value="A=sa,B=sa"/>

在silverlight 应用程序启动项里面

if (e.InitParams.Count > 0)  
\{  
switch (e.InitParams\["A"\].ToString())  
\{  
case"A":  
System.Windows.Browser.HtmlPage.Window.Alert("你好啊");  
break;  
case"":  
break;  
\}  
\}

这样我们就可以根据这个来指定我们每个页面的操作喽.
