检查是否已安装Silverlight [英] Checking is Silverlight is installed

问题描述

我有一个使用Silverlight独立存储的页面。现在，当我的页面加载时，它会显示一个超链接按钮，将用户重定向到Silverlight下载页面（如果他没有安装它）。



我怎么能阻止此链接进入？不仅仅是隐藏它，我如何完全阻止它？

Hi,

I have a page which makes use of Silverlight Isolated Storage. Now, when my page loads, it shows a hyperlink button that redirects the user to Silverlight download page (if he doesn't have it installed).

How can I prevent this link from coming at all? Like not just hiding it, how do I completely prevent it?

推荐答案

要查找是否有Silverlight使用此JS

To find if there is Silverlight use this JS

function hasSilverlight() {
    try {
        try {
            // IE
            var AgControl = new ActiveXObject('AgControl.AgControl');

            return (true);
        }
        catch (e) {
            // Others
            if (navigator.plugins["Silverlight Plug-In"]) {
                return(true);
            }
        }
    }
    catch (e) {
        return (false);
    }
}

如果函数返回true，则删除dom元素...

If the function returns true, then remove dom element...

var el = document.getElementById("button_id");
el.parentNode.removeChild(el);
