查看localhost时的Angular Data绑定问题

Question

所以，我现在有一个数据绑定角度问题，因为我正在使用MEAN Stack并且在我的数据库连接的情况下正常运行。我已经正确添加了JSON条目，只是从我的localhost查看时它们不会出现。

＆＃13;

＆＃13;

var myApp = angular.module('myApp', []);
myApp.controller('AppCtrl', ['$scope', '$http', function($scope, $http) {
    console.log("Hello World from controller");

var refresh = function(){
  $http.get('/eventlist/').then(function(response) {
    console.log("I got the data I requested");
    $scope.eventlist = response.data;
    $scope.event = null;
  });
};

refresh();

  $scope.addEvent = function () {
    console.log($scope.event);
    $http.post('/eventlist/', $scope.event).then(function(response){
      console.log(response);
      refresh();
    });
    $scope.update = function() {
      console.log($scope.event._id);
      $http.put('/eventlist/' + $scope.event._id, $scope.event).then(function(response) {
        refresh();
      })
    };
  };

  $scope.remove = function(id) {
    console.log(id);
    $http.delete('/eventlist/' + id).then(function(response) {
      refresh();
    });
  };

  $scope.edit = function(id) {
    console.log(id);
    $http.get('/eventlist/' + id).then(function(response) {
      $scope.event = response;
    });
  };


  $scope.deselect = function() {
    $scope.event = null;
    refresh();
  };

  }]);
