angular.js - AngularJS Controller中$scope作用域问题

Question

controllers.controller('ctrl', ['$scope', function($scope) {
  console.log($scope);//
  $scope.add = function() {
    console.log($scope);//
  };
}]);

为什么上面两个作用域的输出是不相等的？

Answer 1

Both outputs point to the $scope bound to the controller. The first one is executed when the controller is loaded, and the second one is executed when the add method is called. The execution time and status of the two are different.

Answer 2

It is the same object in itself, and the execution content may be different at different times
