javascript parsing

Question

i have this block of code:

$(document).ready(function() {
    //<![CDATA[  
    var who;

    FB_RequireFeatures(["Api"], function(){ 

        var who = api.get_session().uid;
        alert(who);

        });

        alert("the uid is: "+who);

    //]]> 
});

the problem: the code outside the FB_RequireFeatures block is executing before the one inside it. due to which the value of who is coming out to be undefined.

what am i doing wrong?

Answer 1

You're making a new local who variable. Remove the var from the place where you set who. Also, you can't reference who until the callback to the FB_RequireFeatures function is run.
