• 一起谈.NET技术,SilverLight自动安装 狼人:


    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。

    var isOK = Silverlight.isInstalled("4.0.50524.0");
    if (!isOK) {
    var msgw, msgh, bordercolor;
    msgw
    = 450; //提示窗口的宽度
    msgh = 150; //提示窗口的高度
    titleheight = 25 //提示窗口标题高度
    bordercolor = "#336699"; //提示窗口的边框颜色
    titlecolor = "#99CCFF"; //提示窗口的标题颜色

    var sWidth, sHeight;
    sWidth
    = document.body.offsetWidth; //浏览器工作区域内页面宽度
    sHeight = screen.height; //屏幕高度(垂直分辨率)


    //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)
    var bgObj = document.createElement("div"); //创建一个div对象(背景层)
    //定义div属性,即相当于
    //<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; 918px; height:768px; z-index:10000;"></div>
    bgObj.setAttribute('id', 'bgDiv');
    bgObj.style.position
    = "absolute";
    bgObj.style.top
    = "0";
    bgObj.style.background
    = "#777";
    bgObj.style.filter
    = "progid:DXImageTransform.Microsoft.Alpha(style=2,opacity=25,finishOpacity=75";
    bgObj.style.opacity
    = "0.6";
    bgObj.style.left
    = "0";
    bgObj.style.width
    = sWidth + "px";
    bgObj.style.height
    = sHeight * 2 + "px";
    bgObj.style.zIndex
    = "10000";
    document.body.appendChild(bgObj);
    //在body内添加该div对象


    var msgObj = document.createElement("div")//创建一个div对象(提示框层)
    //定义div属性,即相当于
    //<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; 400px; height:100px; text-align:center; line-height:25px; z-index:100001;"></div>
    msgObj.setAttribute("id", "msgDiv");
    msgObj.setAttribute(
    "align", "center");
    msgObj.style.background
    = "white";
    msgObj.style.border
    = "1px solid " + bordercolor;
    msgObj.style.position
    = "absolute";
    msgObj.style.left
    = "50%";
    msgObj.style.top
    = "20%";
    msgObj.style.font
    = "12px/1.6em Verdana, Geneva, Arial, Helvetica, sans-serif";
    msgObj.style.marginLeft
    = "-225px";
    msgObj.style.marginTop
    = -75 + document.documentElement.scrollTop + "px";
    msgObj.style.width
    = msgw + "px";
    msgObj.style.height
    = msgh + "px";
    msgObj.style.padding
    = "0px";
    msgObj.style.textAlign
    = "center";
    msgObj.style.lineHeight
    = "25px";
    msgObj.style.zIndex
    = "10001";

    var title = document.createElement("h4"); //创建一个h4对象(提示框标题栏)

    //定义h4的属性,即相当于
    //<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>
    title.setAttribute("id", "msgTitle");
    title.setAttribute(
    "align", "right");
    title.style.margin
    = "0";
    title.style.padding
    = "3px";
    title.style.background
    = bordercolor;

    title.style.filter
    = "progid:DXImageTransform.Microsoft.Alpha(startX=20, startY=20, finishX=100, finishY=100,style=1,opacity=75,finishOpacity=100);";
    title.style.opacity
    = "0.75";
    title.style.border
    = "1px solid " + bordercolor;
    title.style.height
    = "18px";

    title.style.font
    = "12px Verdana, Geneva, Arial, Helvetica, sans-serif";

    title.style.color
    = "white";
    title.style.cursor
    = "pointer";
    title.innerHTML
    = "关闭";


    function removeObj() {//点击标题栏触发的事件
    document.body.removeChild(bgObj); //删除背景层Div
    document.getElementById("msgDiv").removeChild(title); //删除提示框的标题栏
    document.body.removeChild(msgObj); //删除提示框层
    }
    title.onclick
    = removeObj;


    document.body.appendChild(msgObj);
    //在body内添加提示框div对象msgObj
    document.getElementById("msgDiv").appendChild(title); //在提示框div中添加标题栏对象title

    var dv = document.createElement("div");
    dv.setAttribute(
    "id", "slInstall");
    dv.setAttribute(
    "style", "font-family:Arial; font-size:14px; ");
    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。";
    document.getElementById(
    "msgDiv").appendChild(dv); //在提示框div中添加提示信息对象txt

    //输出exe
    var downHost = "改为你的地址 例如http://192.168.23.22:8008/download/";
    var osInfo = window.navigator.userAgent;
    var exeName = "";
    if (osInfo.indexOf("Windows NT") >= 0) exeName = "Silverlight4forwindows.exe";
    else if (osInfo.indexOf("PPC Mac OS X") >= 0) exeName = "Silverlight4formac.dmg";
    else if (osInfo.indexOf("Intel Mac OS X") >= 0) exeName = "Silverlight4formac.dmg";
    document.getElementById(
    "downLink").href = downHost + exeName;


    /*判断浏览器*/
    if (osInfo.indexOf("MSIE") == -1) {
    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。";

    }
    else {
    //输出exe安装包
    run_exe = "<OBJECT ID=\"RUNIT\" WIDTH=0 HEIGHT=0 TYPE=\"application/x-oleobject\""
    run_exe += "CODEBASE=\"{0}\">"
    run_exe
    += "</OBJECT>"
    run_exe
    = run_exe.replace("{0}", downHost + exeName);
    document.open();
    document.clear();
    document.writeln(run_exe);
    document.close();
    }

    }

    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)。

    <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;0px;border:0px"></iframe></div>
    </form>
    <script language="javascript" src="autoInstall.js"></script>
    </body>

    3、预览效果。

    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。

    <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>
