如何从我的网站邀请Facebook的朋友

在我的网站上，我基本上希望用户能够邀请他的Facebook朋友。
你知道有一个邀请朋友按钮 - 当用户点击它 - FAcebook小部件打开 - 这将要求用户的Facebook用户名/密码，一旦他登录 - 显示他的朋友列表 - 他可以选择朋友 - 他们会收到他邀请他们加入我的网站的消息。

On my website, I basically want a user to be able to invite his facebook friends. You know have like an Invite Friends button - when the user clicks on it - FAcebook widget opens up - which will ask for the users' facebook username/password and once he logs in - shows him his list of friends - he can select the friends - and they get a message from him inviting them to join my website.
