自动安装silverlight,类似flash自动安装

 

1. 准备js。参考了一个js弹出层的例子。最后自动输出exe,类似flash安装。ie可以自动安装,其他浏览器需要手动下载安装包。

代码
1 var isOK = Silverlight.isInstalled("4.0.50524.0");
2  if (!isOK) {
3 var msgw, msgh, bordercolor;
4 msgw = 450; //提示窗口的宽度
5   msgh = 150; //提示窗口的高度
6   titleheight = 25 //提示窗口标题高度
7   bordercolor = "#336699"; //提示窗口的边框颜色
8 titlecolor = "#99CCFF"; //提示窗口的标题颜色
9
10 var sWidth, sHeight;
11 sWidth = document.body.offsetWidth; //浏览器工作区域内页面宽度
12 sHeight = screen.height; //屏幕高度(垂直分辨率)
13
14
15 //背景层(大小与窗口有效区域相同,即当弹出对话框时,背景显示为放射状透明灰色)
16 var bgObj = document.createElement("div"); //创建一个div对象(背景层)
17 //定义div属性,即相当于
18 //<div id="bgDiv" style="position:absolute; top:0; background-color:#777; filter:progid:DXImagesTransform.Microsoft.Alpha(style=3,opacity=25,finishOpacity=75); opacity:0.6; left:0; width:918px; height:768px; z-index:10000;"></div>
19 bgObj.setAttribute('id', 'bgDiv');
20 bgObj.style.position = "absolute";
21 bgObj.style.top = "0";
22 bgObj.style.background = "#777";
23 bgObj.style.filter = "progid:DXImageTransform.Microsoft.Alpha(style=2,opacity=25,finishOpacity=75";
24 bgObj.style.opacity = "0.6";
25 bgObj.style.left = "0";
26 bgObj.style.width = sWidth + "px";
27 bgObj.style.height = sHeight * 2 + "px";
28 bgObj.style.zIndex = "10000";
29 document.body.appendChild(bgObj); //在body内添加该div对象
30
31
32 var msgObj = document.createElement("div")//创建一个div对象(提示框层)
33 //定义div属性,即相当于
34 //<div id="msgDiv" align="center" style="background-color:white; border:1px solid #336699; position:absolute; left:50%; top:50%; font:12px/1.6em Verdana,Geneva,Arial,Helvetica,sans-serif; margin-left:-225px; margin-top:npx; width:400px; height:100px; text-align:center; line-height:25px; z-index:100001;"></div>
35 msgObj.setAttribute("id", "msgDiv");
36 msgObj.setAttribute("align", "center");
37 msgObj.style.background = "white";
38 msgObj.style.border = "1px solid " + bordercolor;
39 msgObj.style.position = "absolute";
40 msgObj.style.left = "50%";
41 msgObj.style.top = "20%";
42 msgObj.style.font = "12px/1.6em Verdana, Geneva, Arial, Helvetica, sans-serif";
43 msgObj.style.marginLeft = "-225px";
44 msgObj.style.marginTop = -75 + document.documentElement.scrollTop + "px";
45 msgObj.style.width = msgw + "px";
46 msgObj.style.height = msgh + "px";
47 msgObj.style.padding = "0px";
48 msgObj.style.textAlign = "center";
49 msgObj.style.lineHeight = "25px";
50 msgObj.style.zIndex = "10001";
51
52 var title = document.createElement("h4"); //创建一个h4对象(提示框标题栏)
53
54 //定义h4的属性,即相当于
55 //<h4 id="msgTitle" align="right" style="margin:0; padding:3px; background-color:#336699; filter:progid:DXImageTransform.Microsoft.Alpha(startX=20, startY=20, finishX=100, finishY=100,style=1,opacity=75,finishOpacity=100); opacity:0.75; border:1px solid #336699; height:18px; font:12px Verdana,Geneva,Arial,Helvetica,sans-serif; color:white; cursor:pointer;" onclick="">关闭</h4>
56 title.setAttribute("id", "msgTitle");
57 title.setAttribute("align", "right");
58 title.style.margin = "0";
59 title.style.padding = "3px";
60 title.style.background = bordercolor;
61
62 title.style.filter = "progid:DXImageTransform.Microsoft.Alpha(startX=20, startY=20, finishX=100, finishY=100,style=1,opacity=75,finishOpacity=100);";
63 title.style.opacity = "0.75";
64 title.style.border = "1px solid " + bordercolor;
65 title.style.height = "18px";
66
67 title.style.font = "12px Verdana, Geneva, Arial, Helvetica, sans-serif";
68
69 title.style.color = "white";
70 title.style.cursor = "pointer";
71 title.innerHTML = "关闭";
72
73
74 function removeObj() {//点击标题栏触发的事件
75 document.body.removeChild(bgObj); //删除背景层Div
76 document.getElementById("msgDiv").removeChild(title); //删除提示框的标题栏
77 document.body.removeChild(msgObj); //删除提示框层
78 }
79 title.onclick = removeObj;
80
81
82 document.body.appendChild(msgObj); //在body内添加提示框div对象msgObj
83 document.getElementById("msgDiv").appendChild(title); //在提示框div中添加标题栏对象title
84
85 var dv = document.createElement("div");
86 dv.setAttribute("id", "slInstall");
87 dv.setAttribute("style", "font-family:Arial; font-size:14px; ");
88 dv.innerHTML = "<br />安装Microsoft Silverlight后,才能正常浏览该页面。<br /><span id=\"msgSpan\">系统正在下载或者安装此程序。或者 <a href=\"\" id=\"downLink\">点击此处</a> 手动安装。</span><br />安装完成后请重新启动浏览器。";
89 document.getElementById("msgDiv").appendChild(dv); //在提示框div中添加提示信息对象txt
90
91 //输出exe
92 var downHost = "改为你的地址 例如http://192.168.23.22:8008/download/";
93 var osInfo = window.navigator.userAgent;
94 var exeName = "";
95 if (osInfo.indexOf("Windows NT") >= 0) exeName = "Silverlight4forwindows.exe";
96 else if (osInfo.indexOf("PPC Mac OS X") >= 0) exeName = "Silverlight4formac.dmg";
97 else if (osInfo.indexOf("Intel Mac OS X") >= 0) exeName = "Silverlight4formac.dmg";
98 document.getElementById("downLink").href = downHost + exeName;
99
100
101 /*判断浏览器*/
102 if (osInfo.indexOf("MSIE") == -1) {
103 document.getElementById("msgSpan").innerHTML = "您的浏览器不支持自动安装Silverlight,请 <a href=\"\" style=\"text-decoration:underline\" id=\"downLink\">点击此处</a> 手动安装。";
104
105 }
106 else {
107 //输出exe安装包
108 run_exe = "<OBJECT ID=\"RUNIT\" WIDTH=0 HEIGHT=0 TYPE=\"application/x-oleobject\""
109 run_exe += "CODEBASE=\"{0}\">"
110 run_exe += "</OBJECT>"
111 run_exe = run_exe.replace("{0}", downHost + exeName);
112 document.open();
113 document.clear();
114 document.writeln(run_exe);
115 document.close();
116 }
117
118 }
119
120
121

 

2. 在html里面调用该js,将silverlightfor window的安装文件和silverlightformac的安装文件放到根目录,命名为js中写的名字(Silverlight4forwindows.exe,Silverlight4formac.dmg)。

 

代码
<body>
<form id="form1" runat="server" style="height:100%">
<div id="silverlightControlHost">
<object data="data:application/x-silverlight-2," type="application/x-silverlight-2" width="100%" height="100%">
<param name="source" value="ClientBin/AutoInstallSilverlight.xap"/>
<param name="onError" value="onSilverlightError" />
<param name="background" value="white" />
<param name="minRuntimeVersion" value="4.0.50401.0" />
<param name="autoUpgrade" value="true" />
<a href="http://go.microsoft.com/fwlink/?LinkID=149156&v=4.0.50401.0" style="text-decoration:none">
<img src="http://go.microsoft.com/fwlink/?LinkId=161376" alt="获取 Microsoft Silverlight" style="border-style:none"/>
</a>
</object><iframe id="_sl_historyFrame" style="visibility:hidden;height:0px;width:0px;border:0px"></iframe></div>
</form>
<script language="javascript" src="autoInstall.js"></script>
</body>

3. 预览效果,呵呵

4. 可以调整的地方。

删除 这一句,就可以去掉微软的安装提示。

代码
<a href="http://go.microsoft.com/fwlink/?LinkID=149156&v=4.0.50401.0" style="text-decoration:none">
<img src="http://go.microsoft.com/fwlink/?LinkId=161376" alt="获取 Microsoft Silverlight" style="border-style:none"/>
</a>
