如何获得股票价值数量。 应该使用css或js

Question

How to get the share value number. Should use css or javascript :

Answer 1

That's a Facebook widget. You can read how to implement it on Social Plugins - Facebook Developer.

The widget is what brings the share functionality and number of re-shares automatically, depending on how you configure it.

If you do not want the whole button as your screenshot, but only the number of shares, you could make call to:

http://graph.facebook.com/?id=http://stackoverflow.com

It returns a JSON with both comment count and share count.

See this git page for other Share numbers.
