angular js中控制器之间的数据共享

angular.module('myApp').service('sharedData', function() {
  var data = {};

  return {
    getData: function() {
      return data;
    },
    setData: function(newData) {
      data = newData;
    }
  };
});

angular.module('myApp').controller('Controller1', function($scope, sharedData) {
  $scope.data = sharedData.getData();

  // 在控制器1中设置数据
  $scope.setData = function(newData) {
    sharedData.setData(newData);
  };
});

angular.module('myApp').controller('Controller2', function($scope, sharedData) {
  $scope.data = sharedData.getData();

  // 在控制器2中设置数据
  $scope.setData = function(newData) {
    sharedData.setData(newData);
  };
});
