外部javascript 方法修改 angularjs 中$rootScope和$scope

1. 修改 $rootScope

var $body = angular.element(document.body);   // 1
var $rootScope = $body.scope().$root;         // 2
$rootScope.$apply(function () {               // 3
    $rootScope.notesconfigs.outpath = path;
});

   2. 修改 $scope

var appElement = document.querySelector('[ng-controller=mainController]');//获得绑定controllerdom节点
var $scope = angular.element(appElement).scope(); //获得$scope对象
$scope.$apply();//刷新数据

获取当前元素的$socpe:     angular.element(domElement).scope() to get the current scope for the element
获取当前app的injector：   angular.element(domElement).injector() to get the current app injector
获取当前元素的controller：angular.element(domElement).controller() to get a hold of the ng-controller instance.
