用户从服务器下载silverlight.exe插件

经过测试发现上边的方法仅仅支持：客户端没有安装Silverlight插件的请客。当安装了低版本后则任然会跳转到微软的路径..原以为修改silverlight.js可以解决，但是尝试很多后任然不行。于是根据网上提示通过JavaScript调用silverlight.js动态加载silverlight后，终于实现。大致代码如下：

<script type="text/javascript">
        //用于控制DIV的显示，直接跟ID属性
        function showhidediv(id){
        var sbtitle=document.getElementById(id);
            if(sbtitle){
               if(sbtitle.style.display=='block'){
               sbtitle.style.display='none';
               }else{
               sbtitle.style.display='block';
               }
            }
        }

        function LoadSilverlight() {
            //插件版本判断
            var theVersion = "4.0.50401.0"; //设定版本检测值
            var isInstalled = Silverlight.isInstalled(theVersion);
            if (!isInstalled) {
                //alert("您的Silverlight插件需要升级,请下载并安装！"); // 安装(提示)体验
                //window.open("http://localhost:10968/Silverlight4.0.exe");
                showhidediv("downSL");

            } else {
                //JavaScript 将 Silverlight 添加到网页
                Silverlight.createObjectEx({
                    source: "ClientBin/Main_src.xap",
                    parentElement: silverlightControlHost,
                    id: "sl4",
                    properties: {
                        width: "100%",
                        height: "100%",
                        background: "white",
                        alt: "",
                        version: theVersion
                    },
                    events: {
                        onError: onSilverlightError,
                        onLoad: onSLLoad
                    },
                    initParams: "bgImage=1.png",//参数
                    context: ""
                });

            }
         }
         function onSLLoad(plugIn, userContext, sender) {
             //alert("加载...");
        }
    </script>

<body onload="LoadSilverlight()">
    <form id="form1" runat="server" style="height: 100%">

    <div id="downSL" style="display:none" >
        <a href="ClientBin/Silverlight4.0.exe" style="text-decoration: none;">
            <img src="ClientBin/InstallSilverlight.png" alt="获取 Microsoft Silverlight" style="border-style: none" />
        </a>
    </div>
    <div id="silverlightControlHost">
        <iframe id="_sl_historyFrame" style="visibility: hidden; height: 0px; width: 0px;
            border: 0px"></iframe>
    </div>
    </form>
</body>

希望对大家有用......
