getUser()
is not returning anything. You need to return the promise from the Spotify.getCurrentUser()
, and then when you return names
within that it is returned by the outer function.
function getUser() {
if ( $localStorage.token == undefined) {
throw alert("Not logged in");
}
else {
return Spotify.getCurrentUser().then(function(data) {
var names = JSON.stringify(data.data.display_name);
console.log(names)
return names;
})
}
}
The above answered why you were getting undefined
when calling getUser()
, but if you want to work with the end result you also want to change how you're using the value you get from getUser - it returns a promise object, not the end result you're after, so your code wants to call the promise's then
method when the promise gets resolved:
getUser() // this returns a promise...
.then(function(names) { // `names` is the value resolved by the promise...
$scope.names = names; // and you can now add it to your $scope
});
