對於PC版大尺吋的螢幕，當網站要 feed 資料到 facebook 時，可以使用 javascript SDK 的
FB.ui => method:'feed' 方式處理，參考位置。此方法會popup小視窗讓user可以分享資料出去。

但是遇到手機版網頁就有點麻煩，實測上手機版的 chrome 會出現轉不停的情況，無法分享；而iPhone則是另開新頁面處理，可以成功但是會多一個分頁。所以手機版網頁建議使用 redirect 方式處理分享機制，參考位置
​

    var fbUrl = "https://www.facebook.com/dialog/feed?" +

    "app_id=122465741241119&display=touch" +

    "&link=" + encodeURIComponent("http://www.shopunt.com/tch/FixPage.aspx?id=525") +

    "&picture=" + encodeURIComponent("http://www.shopunt.com/tch/event/2014-nail-enrollment/fb_200x200.jpg") +

    "&description=" + encodeURIComponent("市價不斐的光療DIY教學，UNT傾囊相授！10場巡迴免費教學，讓妳輕鬆掌握光療DIY訣竅，並搶先體驗秋冬最新流行色！現場打卡，再送時尚美甲工具組") +

    "&redirect_uri=" + encodeURIComponent("http://www.shopunt.com/tch/event/2014-nail-enrollment/Handler.ashx?fun=FBCallback");

當然以 redirect 處理與 javascript 方式處理是兩種不同的方式，redirect 方式的 callback 網址 (redirect_uri)要接收facebook 導回的 post_id , javascript 方式則是 callback function 處理 post_id
