I am trying to understand AngularJS's controllerAs syntax

angularjs,jasmine,karma-jasmine,angularjs-controller,angularjs-http

It should be app.controller('firstController', ['$scope', function($scope){ $scope.name = "Tim"; }]); Also, controllerAs syntax is synthetic sugar for the scope simply, you avoid using this: <div ng-controller="oneCtrl"> {{name}} </div> And instead use this: <div ng-controller="oneCtrl as one"> {{one.name}} </div> Which helps tremendously when you have nested controllers....

View does not reflect the data from $http.get(inside an angularjs controller)

Define a $scope variable outside xyzFunc, bind this variable, then set it's value from $http callback. Since you use angular's $http you do not have to worry about apply. Added the code for better visualization: app.controller('ViewClockController', function($scope, $http, $interval){ $scope.viewAll = this; $scope.viewAll.widget = []; $scope.xyzFunc = function(){ $http.get('/statistics/clock').success(function(data) {...

Why wouldn't you use explicit annotations when defining controllers in AngularJS?

javascript,angularjs,dependency-injection,angularjs-controller

The inline array annotation is simply a workaround over Javascript limitations to allow Angular code to be minified and not to stop working.

AngularJS: Should I convert directive's linking function to a controller?

I consider it best practice to move initialization code and/or exposing API functions inside of a directive's controller, because it serves two purposes: 1. Intialization of $scope 2.

Same “controller as” name in angular js directive breaks function in parent controller

javascript,angularjs,angularjs-directive,angularjs-controller

Testing variable binding using Controller As syntax

Start by instantiating the controller: ctrl = $controller('LoginFormCtrl'); Angular will inject the AuthService. There is no other dependency to inject in the controller, so passing a scope or login_details won't work.

Injecting a Angular service into controller results in $injector:unpr error (using AngularBooter)

angularjs,angularjs-scope,angularjs-ng-repeat,angularjs-controller

AngularJS: assign $http.get data to variable

javascript,angularjs,angularjs-scope,angularjs-controller,angularjs-http

Angular custom directive: a strange error occurs when set controller attribute to `function(scope){}`

javascript,angularjs,angularjs-directive,angularjs-controller
