I need to get the access token from FB.login method in Javascript SDK. My login code is
FB.login(function(response) {
if (response.session) {
if (response.perms) {
} else {
// user is logged in, but did not grant any permissions
alert("No Permission..");
}
} else {
// user is not logged in
alert("Please login to facebook");
}
}, {perms:'read_stream,publish_stream,offline_access'});
Is there any way to get access token? I am able to get the access token using PHP.
This question is related to

response.session doesn't work anymore because response.authResponse is the new way to access the response content after the oauth migration.
Check this for details:

FB.getAuthResponse()['accessToken']
response.session.access_token doesn't work in my code. But this works:
response.authResponse.accessToken
FB.login(function(response) { alert(response.authResponse.accessToken);
}, {perms:'read_stream,publish_stream,offline_access'});
