考虑到收藏夹图标并不总是位于基本URL上，我需要一种从通用网页获取收藏夹图标URL的方法。

P.s.无需使用外部服务或库。

最佳答案

这似乎可行:

var getFavicon = function(){
    var favicon = undefined;
    var nodeList = document.getElementsByTagName("link");
    for (var i = 0; i < nodeList.length; i++)
    {
        if((nodeList[i].getAttribute("rel") == "icon")||(nodeList[i].getAttribute("rel") == "shortcut icon"))
        {
            favicon = nodeList[i].getAttribute("href");
        }
    }
    return favicon;
}

alert(getFavicon());​
