Facebook login not responding to FB.login response - facebook

Question

I am working on a android phonegap application with facebook integration.
FB.login(function(response) function has a response handler it is being called when
user click on fb button, but its not getting into the function response
or alert('test') every time. it gets into this script only when i hit
around 5 or 6 times. wat i need is to fetch the access token the very first time i logged into facebook. i have gone through a lot of links regarding this but
cant find an exact solution for this...
FB login callback function not responding if user is already logged in facebook
Even this question seems to be same but i cant figure it out my solution.
this is the code am working :
<div id="data">Hello Facebooktesters, loading ...</div>
<button onclick="login()">Login</button>
<button onclick="me()">Me</button>
<button onclick="logout()">Logout</button>
<button onclick="Post()">facebookWallPost</button>
<script type="text/javascript">
document.addEventListener('deviceready', function() {
try {
alert('Device is ready! Make sure you set your app_id below this alert.');
FB.init({
appId : "xxxxxxxxxxxxxxx",
nativeInterface : CDV.FB,
useCachedDialogs : false
});
document.getElementById('data').innerHTML = "FB init executed";
} catch (e) {
alert(e);
}
}, false);
function me() {
FB.api('/me/friends', {
fields : 'id, name, picture'
}, function(response) {
if (response.error) {
alert(JSON.stringify(response.error));
} else {
var data = document.getElementById('data');
fdata = response.data;
console.log("fdata: " + fdata);
response.data.forEach(function(item) {
var d = document.createElement('div');
d.innerHTML = "<img src="+item.picture+"/>" + item.name;
data.appendChild(d);
});
}
var friends = response.data;
console.log(friends.length);
for ( var k = 0; k < friends.length && k < 200; k++) {
var friend = friends[k];
var index = 1;
friendIDs[k] = friend.id;
//friendsInfo[k] = friend;
}
console.log("friendId's: " + friendIDs);
});
}
function login() {
FB.login(function(response) {
alert('test');
if (response.authResponse) {
alert('logged in');
var access_token = FB.getAuthResponse()['accessToken'];
alert(access_token);
window.location = "test.html"
} else {
alert('not logged in');
}
}, {
scope : "email"
});
}
function logout() {
alert('test');
FB.logout(function(response) {
alert('logged out');
//window.location.reload();
});
}
function Post(ele) {
var domain = 'http://192.168.0.46:8082/';
console.log('Debug 1');
var params = {
method: 'feed',
name: 'test - test',
link: domain+'test/test/showproddetails.action?product.productId=1',
picture: 'http://www.careersolutions.com/test.png',
caption: 'test',
description: 'test'
};
console.log(params);
FB.ui(params, function(obj) { console.log(obj);});
}
</script>
Thank you,

Answer 1

You are missing semicolon in this line :
window.location = "test.html"

This question was posted a while ago but I would like to point out something. FB.login function opens a popup dialog asking if the user would like to log in to your app using Facebook. It is generally recommended that it be run after clicking a button as most browsers would block popup dialogs when a page loads. If the user had previously authorized your app then the popup dialog redirects back to your app and closes the dialog box (assuming your app is a website).
If what you intended to do was to check whether a user is logged in to your app upon page load, then it's recommended that you instead use FB.getLoginStatus method like so
function checkLoginState() {
FB.getLoginStatus(function(response) {
// Check response.status to see if user is logged in
alert(response.status);
});
}
