facebook - Can you use Facebook's old Javascript SDK and new Javascript SDK on the same webpage?

Question

Can we use the old and new Facebook Javascript SDK on the same webpage? (the old Javascript SDK is used by the "Login with Facebook" and "Share" button. The new Javascript SDK is to be used by the "Like" button)

The old Javascript SDK is included by Facebook's

FeatureLoader.js.php
xd_receiver.html
docs: http://developers.facebook.com/docs/reference/oldjavascript/

The new Javascript SDK is included by Facebook's

connect.facebook.net/en_US/all.js
docs: http://developers.facebook.com/docs/reference/javascript/

they both define FB, and they conflict with each other.

不，这是不可能的，它要么是一个，要么是另一个。
