How to access the angular $scope variable in browser's console?;

javascriptangular.element('[ng-controller=ctrl]').scope();
angular.element(document.querySelector('#id')).scope();

The most rustic solution...window['scope']=$scope

Write the angular controller in the function expression that is executed immediately:

    var app = angular.module('app', []);
    app.controller('ctrl', function($scope) {
        $scope.aaa = 1;
    });

Then introduce it into regular js

(function(app) {
    $scope.aaa = 2;  //有什么办法可以让这个实现？
})(app);
