internet explorer - Javascript SDK not working in Facebook Canvas App IE7/8 -

-

i developing canvas app , got working required in browsers apart ie 7/8 cannot app auto redirect facebook login screen if users not logged facebook.

i suspect ie not getting state of users through getloginstatus method , therefore cannot fire javascript redirect, , because of remove app functionality not working.

i have ran code through online js lint tool , have tidied few things , tried again having no luck

if try outside of facebook e.g https://mydomain.com/directory, js sdk works , redirects facebook login page not same within facebook iframe

i have noticed within facebook iframe system cannot browser mode , uncertain whether have bearing

here complete code 

$(document).ready( function() { //facebook js sdk window.fbasyncinit = function () {     fb.init({         appid: 'xxxxxxxxxxxxxxxxx',         channelurl: '//www.mydomain.co.uk/facebook-notes/channel.html',         // channel file         cookie: true,         xfbml: true,         oauth: true,         status: true     });     fb.getloginstatus(function (response) {         if (response.status === 'connected') {             //alert('hello');             $('a#remove-app').click(function () {                 var request = response.authresponse.accesstoken;                 $("#dialog:ui-dialog").dialog("destroy");                 $("#dialog-confirm").dialog({                     height: 140,                     modal: true,                     position: [236, 101],                     buttons: {                         "yes": function () {                             if (request) {                                 $.ajax({                                     url: 'https://graph.facebook.com/me/permissions',                                     type: 'get',                                     data: 'method=delete&access_token=' + request,                                     datatype: 'jsonp',                                     success: function (response) {                                         top.location.href = 'http://facebook.com';                                     }                                 });                             }                         },                         cancel: function () {                             $(this).dialog("close");                         }                     }                 });                 return false;             });         } else {             //alert('user not logged in');             var oauth_url = 'https://www.facebook.com/dialog/oauth/';             oauth_url += '?client_id=xxxxxxxxxxxxxxx';             oauth_url += '&redirect_uri=' + encodeuricomponent('https://apps.facebook.com/app_name/');             oauth_url += '&scope=email';             window.top.location = oauth_url;         }     },         true);     $('a#invite-a-friend').click(function () {         sendrequestviamultifriendselector();     });     // multi friend selector facebook     function sendrequestviamultifriendselector() {         fb.ui({             method: 'apprequests',             message: 'come , join app on facebook'         });     }     function requestcallback(response) {         alert (response);     } }; // load sdk asynchronously (function (d) {     var js,         id = 'facebook-jssdk',         ref = d.getelementsbytagname('script')[0];     if (d.getelementbyid(id)) {         return;     }     js = d.createelement('script');     js.id = id;     js.async = true;     js.src = "//connect.facebook.net/en_us/all.js";     ref.parentnode.insertbefore(js, ref); }(document)); });

i appreciate

most manifestation of old third-party-cookies problem. search third party cookies / p3p policy find solutions should make work.
