Facebook share in widget

Question

I have read that the Facebook sharer is deprecated, So I wanted to know how can I create a share button in my widget that will work from any domain (not just the app domain), via the js SDK (Preferably).

For example:
I have my app registered on myserver.com
And someone downloaded my widget on hisservers.com, I want the share to work from there and post to his wall.

How can I do so?

You can use the FB.ui Feed dialog to prompt the user to publish a story on their feed, and specify your link in the function. Like so

function postLink() {
    var obj = {
      method: 'feed',
      link: 'http://myserver.com',
      picture: 'a_picture',
      name: 'My Server',
      description: 'Sharing MyServer from HisServer.'
    };

    function callback(response) {
      console.log(response['post_id']);
    }

    FB.ui(obj, callback);
  }

Of course you'll have to also include the proper initialization for the JS SDK.
