我用的有
external.AddToFavoritesBar(sURL, sTitle, '');
window.external.addFavorite(sURL, sTitle);
window.sidebar.addPanel(sTitle, sURL, "");
但都不好使 ，请求一个ie8下 js 加入收藏夹，好使的代码·~~~~~~~？？
------解决方案--------------------------------------------------------
IE8？？？就这样就可以啊。。
- HTML code
<a href="javascript:window.external.AddFavorite('http://www.dtan.so','Dtan网址导航')">收藏本站 </a>
------解决方案--------------------------------------------------------
加入收藏夹需要用户点击确认，
ie8的实现方法是，如果不是用户点击的，默认是忽略执行的，也不报错的。
不要页面打开使用 js 直接自动运行加入收藏夹的代码。
你可以<input type=button onclick="window.external.AddFavorite('http://xxx','xx')">测试，才能知道是否支持

文档写的很清楚
Windows Internet Explorer 8 and later. For security reasons, the AddFavorite method must be called as a response to a user-initiated action, such a mouse click. If called from a different context, such as the onload event of the body element, the AddFavorite method fails silently.
