Access the result of $http.get in Angularjs outside function

Question

trying to create a Date object (using time only) and accessing that value outside of my function

Any help would be appreciated. See code below or my plunker

  var objts = "";

  $scope.today = function() {

        $http.get('time.json').success(function(data, status, headers, config) {

        objts   = new Date(data.time_start);
        objte   = new Date(data.time_end);

        console.log(data);
    }).error(function(data, status, headers, config) {
        console.log("No data found..");
  });  

    $scope.dt = objts;  // ---- Trying to use value of objts here ----

  };
  $scope.today();

Thanks

you will only get async call response in their callbacks..

The get method is executed asynchronously. You are currently setting the $scope.dt value outside the get promise resolution function.

You should set the $scope.dt variable when the get promise resolve:

$scope.dt = null;

$scope.today = function() {
  $http.get('time.json').success(function(data) {
    var objts = new Date(data.time_start);
    var objte = new Date(data.time_end);
    $scope.dt = objts;
    console.log(data);
  }).error(function(data) {
    console.log("No data found..");
  });
};
$scope.today();

Edit
Your problem actually comes from the way you create your date. You should do something like:

$scope.dt = Date.parse("2016-01-01 " + data.time_start);

See the Dates documentation, or moment.js, and forked Plnkr

Ok that makes sense, but I get the current time (not 08:00:00, the value in my json I want) when I do that. My plunker was updated to show what I mean

The problem lies in your date creation. You should do something like Date.parse("2016-01-01 "+data.time_start);
