How is angularjs's $scope manipulated by external functions?

Question

Two js files are referenced in the page at the same time, one is the control of angularjs, and the other is regular js

control:

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

Regular js:

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

I solved it by google, http://www.cnblogs.com/czcz1024/p/3808345.html，浪费资源了，sorry。

Make good use of Google search. This kind of problem you often encounter is usually found on StackOverflow

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

Answer 3

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);
