But if I want to use $scope.tempObject after callback so how can I use it. ?
You need to chain from the httpPromise. Save the httpPromise and return the value to the onFullfilled handler function.
//save httpPromise for chaining
var httpPromise = $http({
method: 'GET',
url: '/myRestUrl'
}).then(function onFulfilledHandler(response) {
$scope.tempObject = response
console.log("Temp Object in successCallback ", $scope.tempObject);
//return object for chaining
return $scope.tempObject;
}, function errorCallback(response) {
});
Then outside you chain from the httpPromise.
httpPromise.then (function (tempObject) {
console.log("Temp Object outside $http ", tempObject);
});
For more information, see AngularJS $q Service API Reference -- chaining promises.
It is possible to create chains of any length and since a promise can be resolved with another promise (which will defer its resolution further), it is possible to pause/defer resolution of the promises at any point in the chain. This makes it possible to implement powerful APIs.1
