ขอถามเกี่ยวกับการดึง email ด้วย facebook graph api หน่อยครับ

$useraq->getProperty("email");

var fb_data;
var fb_config = { appId: '99999999999999999', cookie: true, xfbml: true, oauth: true, version: 'v2.5' };
function fb_login(){
	FB.getLoginStatus(function(response){
		if( response.status==='connected') fb_get_api('login');
		else{
			FB.login( 
				function(response){if(response.authResponse){state='';fb_get_api('login');}}, 
				{scope:'email,user_photos,publish_actions'}
			)
		}
	})
}
function fb_get_api(opt){
	FB.api( '/me',
	{fields: "id,about,age_range,picture,bio,birthday,context,email,"+
				"name,first_name,last_name,middle_name,gender,"+
				"hometown,link,location,timezone,website,work"},
	function(response) {
		fb_log( 0,0,response);
		fb_data = response;
		$.ajax({
			url: '/Login/'+(opt=='login'? 'fb_login' : 'fb_data')+'/rnd/'+(Math.random()*100000),
			type: 'POST', data:{ ro: response}
		}).done(function(msg){
			var rs = $.parseJSON(msg); 
			if( rs.msg=='isMember' && opt=='login') location.reload();
			if( rs.msg=='noMember' && opt=='login') location.href='/Register';
		});
	}) 
}
function fb_log( id, sender, response ){
	$.ajax({
		url: '/FaceView/log/id/'+id+'/sender/'+sender+'/rnd/'+(Math.random()*100000), 
		type: 'POST', data:{ ro: response}
	});
}
$(document).ready(function(e) {
	$.ajaxSetup({ cache: true })
	$.getScript('//connect.facebook.net/en_US/all.js', function(){
		FB.init( fb_config);
		FB.getLoginStatus(function(response){ if( response.status==='connected' ) fb_get_api(''); });
	});
});
