AngularJS $injector是很多神奇的地方，所以如果你把它暴露在AngularJS代码之外，你可以把它连接到非AngularJS代码上，如下所示：

//A simple AngularJS service:
app.service('myService', function() {
  this.message = "This is my default message.";
});

//Expose the injector outside the angular app.
app.run(function($injector, $window) {
  $window.angularInjector = $injector;
});

//Then use the injector to get access to the service.
//Make sure to wrap the code in a `$apply()` so an 
//AngularJS digest cycle will run
function nonAngularEventHandler() {
  angularInjector.invoke(function(myService, $rootScope) {    
    $rootScope.$apply(function() {
      myService.message = "Now this is my message."
    });
  });
}

编辑：或者，像这样简化通话。

//Instead of exposing the $injector directly, wrap it in a function
//which will do the $apply() for you.
app.run(function($injector, $window, $rootScope) {

  $window.callInMyAngularApp = function(func) {
    $rootScope.$apply(function() {
      $injector.invoke(func);
    });
  }

});

//Then call that function with an injectable function like so.
function nonAngularClick() {
  callInMyAngularApp(function(myService) {    
      myService.message = "Now this is my message."
  });
}

//And remember if you're minifying, you'll want the minify-safe
//version of the injectable function like this
function nonAngularClick() {
  callInMyAngularApp(['myService', function(myService) {    
      myService.message = "Now this is my message."
  }]);
}

更新：（最后一个我保证！）上面的可以很好地工作，但是你可能需要考虑公开一个定义良好的API，而不是一个通用的可注入接口。

//Now I have a limited API defined in a service
app.service("myExternalApi", function($rootScope, myService) {
  this.changeMyMessage = function(message) {
    $rootScope.$apply(function() {
      myService.message = message;
    });
  };
});

//And I just expose that API
app.run(function($window, myExternalApi) {
  $window.myExternalApi = myExternalApi;
});

//And the call from outside of angular is much cleaner.
function nonAngularClick() {
  myExternalApi.changeMyMessage("Now this is my message.");
}

var Chat = angular.element(document.querySelector('#chatModule')).scope();

    if(!Chat) return;

    if(Chat.chatCtrl.initChatFlag) {
        Chat.chatCtrl.setInformation();
    }else{
        console.log('Chat has not been initialized');
    }
