Undefined value for email in fb login

Question

I want to get the users email id from facebook i user java script SDK for getting email id

  <script>

(function(d){
    var js, id = 'facebook-jssdk'; if (d.getElementById(id)) {return;}
js = d.createElement('script'); js.id = id; js.async = true;
js.src = "https://connect.facebook.net/en_US/all.js";
d.getElementsByTagName('head')[0].appendChild(js);
}(document));

     $(document).ready(function() {
     $('#fb_button').click(function() {
     FB._https = (window.location.protocol == "https:"); // Required because FB Javascript SDK tries to submit https to http
    FB.init({appId:"{app_id}", cookie:true, status:true, xfbml:true, oauth:true , version:'v2.5'});
    FB.login(function(response) {

    if (response.authResponse) {
    console.log('Welcome!  Fetching your information.... ');
    console.log(response); // dump complete info
    access_token = response.authResponse.accessToken; //get access token
    user_id = response.authResponse.userID; //get FB UID


    FB.api('/me', function(response) {
        user_email = response.email; //get user email
        alert(user_email);
  });  
  }
  else{
  alert('no response');
  }   
}, {
    scope: 'email'

    });

     });
});


(function() {
    var e = document.createElement('script');
    e.src = document.location.protocol + '//connect.facebook.net/en_US/all.js';
    e.async = true;
  //  document.getElementById('fb-root').appendChild(e);
    }());
     </script>

it returns response but undefined value for alert i copy paste the same code in another site with different app_id it returns the email id for same user. i also tried PHP SDK but same result.may be this question is duplicate .but i tried almost all answers of those questions.

Anyone got any idea what's going wrong please?

Thanks in advance

No, for email you don't need to Submit App for Review. Your flow is not correct, please correct your flow. — Shameem Ahmed Mulla, Nov 16 '15 at 07:52

"Declarative Fields" is what you need, see the changelog: https://developers.facebook.com/docs/apps/changelog#v2_4

For example:

FB.api('/me', {fields: 'name,email'}, function(response) {
    user_email = response.email; //get user email
    alert(user_email);
});
