FB ID is returning as undefined

I am using var userID = (FB.getAuthResponse() || {}).userID; to get ID of logged in user, FB .init is initialized properly. The issue that I am encountering is If I put 

var userID = (FB.getAuthResponse() || {}).userID;

inside document.ready(); it is returned as undefined whereas if I put it in some javascript function and call that function on a button click, it works perfectly fine.

Anyone know what could be the issue?

I am also getting this when I try to access it directly on my website:

XMLHttpRequest cannot load {CALL o be MADE}. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin '{MY WEBSITE ADDRESS}' is therefore not allowed access. (index)

PS: I don't get the above mentioned error in my facebook page tab, I only get this when I try to access directly my website.

I suggest using the asynchronous way to check if a user is logged in and to get his id:

You should never use this method at page load time. Generally, it is safer to use FB.getLoginStatus if you are unsure.

Check out the Facebook docs for code and information: https://developers.facebook.com/docs/reference/javascript/FB.getLoginStatus

Of course you should call this right after FB.init.
