用JS获取网站的图标 [英] Get website's favicon with JS

问题描述

我想知道是否可以通过使用JavaScript的URL获取网站的网站图标.

I am wondering if it is possible to get a website's favicon by an URL with JavaScript.

例如，我有一个URL http://www.bbc.co.uk/，我想获取<link rel="icon" .../>元标记-http://www.bbc.co.uk/favicon.ico中所述的图标图标的路径.

For example I have an URL http://www.bbc.co.uk/ and I would like to get path to favicon described in <link rel="icon" .../> meta tag - http://www.bbc.co.uk/favicon.ico.

我有很多网址，因此不应加载每个页面并搜索我认为的link标记.

I have many URLs so that should not load every page and search for link tag I think.

有什么想法吗?

推荐答案

您可以为此使用YQL

You could use YQL for that

http://query.yahooapis.com/v1/public/yql?q=select%20*%20from%20html%20where%20url%3D"http://bbc.co.uk/"and%20xpath%3D"/html/head/link[@rel%3D'icon']%20|%20/html/head/link[@rel%3D'ICON']%20|%20/html/head/link[@rel%3D'shortcut%20icon']%20|%20/html/head/link[@rel%3D'SHORTCUT%20ICON']"&format=json&callback=grab

显示Feed网站图标Greasemonkey脚本使用的查询.

您可以在YQL控制台中编写查询，但是需要登录(顺便说一句，不要使用查询):

You can write queries in YQL console, but it requires to login (btw, using queries don't):

http://developer.yahoo.com/yql/console/#h=select%20*%20from%20html%20where%20url%3D%22http%3A//bbc.co.uk/%22and%20xpath%3D%22/html/head/link%5B@rel%3D%27icon%27%5D%20%7C%20/html/head/link%5B@rel%3D%27ICON%27%5D%20%7C%20/html/head/link%5B@rel%3D%27shortcut%20icon%27%5D%20%7C%20/html/head/link%5B@rel%3D%27SHORTCUT%20ICON%27%5D%22

如果存在favicon，但不位于domain.com/favicon.ico

It is better than http://www.google.com/s2/favicons?domain=www.domain.com , in case favicon exists, but doesn't located in domain.com/favicon.ico
