AngularJS: Understanding RootScope ($rootScope)

[@rightpoint8881]

Great job with these tutorials. After trying almost a dozen videos on AngularJS, this is the series that finally made it "click" for me. Some people have complained that you repeat yourself too much at times, but I think that's needed when you are addressing an audience completely new to the topic.

[@JeremiahKellogg]

This helped me solve an issue I've been trying to fix for weeks. I understand rootScope so much better now. Thanks!

When do you use multiple angular modules

[@dipanshusharma9851]

Sir, the amount of tax and net are not showing while I am running the code...please help!! @TechCBT

[@amangrover6329]

A controller is instantiated when angular reads ng-controller directive and it is then that the scope pertaining to that controller is glued with the controller object .Would this be the case with the rootScope object also? Would the module be instantiated when angular reads the ng-app directive only?

[@NavneetThePrakash]

I can't thank you enough for your awesome tutorials, When will you teach us Angular 2?

[@Techcbt-online]

Soon after Angular 1

[@Techcbt-online]

Thank you.

[@priyankadodda5022]

Nice Explanation Sir.Thank you soooo much.Please upload multiple ng-app with multiple rootScope in in single web page.

[@Techcbt-online]

Sure..thanks

[@ivanmarusic222]

So, can we use "$rootScope" like some kind of constant or there is better way?

[@Techcbt-online]

anything you specify in function parameters are just variables. It is just a general convention to use "$rootScope". For that matter, you can just use "r"

[@ivanmarusic222]

Thank you for explanation.

[@longlongvs2012]

hi ~what is the different between $rootScope and the Window Object

[@longlongvs2012]

i mean we can gained data from the customer Window Object

[@Techcbt-online]

$rootScope is angular object. Window is JavaScript Object. $rootScope is inherited by child scopes. Not by Window. etc.

[@shankarer00384]

[@parimalchandwaskar1700]

@Tech CBT , I did not pass rootScope as a param in controller still I can access the value defined in run block at module. Is this a good representation and how? Thanks Hello {{name}}. Your tax amount is ${{taxAmount}} ----------------------- var app = angular.module('sample', []) .run( ['$rootScope', function($rootScope){ $rootScope.taxAmount = 40; }]); app.controller('emp', ['$scope', function($scope){ $scope.name = "John"; }]);

$rootScope.$on calling twice why i didnt understanding.belw is the code $rootScope.$emit("saveAnnotations", { data: config.featureObj }); $rootScope.$on("saveAnnotations", function (e, data) { } can anybody help me for this.

[@ashishranjan7812]

Great explanation

[@ThePomelo09]

the best tutorial!!!!

[@ruchirai5775]

Hi , What is being explained in modifying root scope is contrary to how code is behaving.Please check. angular.module('myApp', []) .run(function($rootScope) { $rootScope.test = "myTest" }).controller('emp', function($scope) { $scope.test="myTest1" }).controller('empdetails', function($scope) { $scope.test="myTest2" }); {{test}} {{test}} In this If I change shared rootscope it only change in that div not anywhere else.
