如何从Facebook JSON获取ID值？

Question

basically, I have input where you type the facebook user ID and and then the script fetches its value to get the link to facebook graph like:

var faceuserID = document.getElementById('userID').value;
$.getJSON('http://graph.facebook.com/' + faceuserID, function(data) {

}

Then I can get the link to the facebook graph which returns the JSON array. However I need only the ID value to some new variable. How do I get it?

Answer 1

You have to you attr(jquery) . ID is attribute, not a value.
