I have implemented a code to show a busy icon and this is it
angular.module("app", [])
.controller('UploadCtrl', function ctrl ($scope, $timeout) {
$scope.busy = false;
$scope.submit = function () {
$scope.busy = true;
// pretend to make an http call...
$timeout(function () {
$scope.busy = false;
}, 10000);
};
});
This is the index.html file

<button ng-disabled="busy" ng-click="submit()">Submit <i class="fa fa-spinner fa-spin" ng-show="busy"></i></button>

When I run the code the busy loader keeps running. Please what could be wrong.
This is the plunk I have made.

You reference a controller which not exists. Fix the HTML code
<body ng-app="app" ng-controller="UploadCtrl">
angular.module("app", [])
.controller('UploadCtrl', function ctrl ($scope, $timeout) {
$scope.busy = false;
In the above code you have name your controller as 'UploadCtrl' ,where as, in HTML file
<body ng-app="app" ng-controller="ctrl">
controller is 'ctrl' , due to which it can't load the controller hence the angular part is not executed.
Change your app.js to
angular.module("app", [])
.controller('ctrl', function ($scope, $timeout) {..}
View plunkr
Also I removed ng-disabled from <button ng-disabled="busy" ng-click="submit()">Submit since you are already using $scope.busy = false; as soon as script loads.
Checkout ngController .

I'm trying to trigger a click on a link, but it only runs the ng-click
From MyScript.js:
$timeout(function () {
angular.element(document.querySelector('#cancelButton')).triggerHandler('click');
}, 0);
And from Index.cshtml:
<input class="popupButton" type="button" value="Anuluj" />
I know that the way I did with
<a...><input... /></a>
is wrong,
but the important thing is: how to it to click the link and the ng-click?
I have written a simple program to navigate to the link.
<!DOCTYPE html>
<html>
<head>
<title></title>
<meta charset="utf-8" />
</head>
<body>
<div ng-app="app">
<div ng-controller="ctrl">
Redirect to Click Me!
</div>
</div>
<script src="../lib/angular.js"></script>
<script>
var app = angular.module('app', []);
app.controller('ctrl', function ($scope, $log, $window) {
$scope.redirect = function () {
var url = "http://www.google.com";
$window.location.href = url;
};
});
</script>

How to use window.onload function inside a controller.
window.onload= function() {
console.log("Hi Page loaded")
};
The controller is not applicable for the full page.
I want to execute a function after my controller loads at-least.
You can use ng-init and invoke your necessary function using the same directive
var app = angular.module('DemoApp', [])
app.controller('akuaController', function($scope) {
$scope.load = function() {
alert("Window is loaded");
}
});

Changing the example from Angular $window
Your Controller
angular.module('windowExample', [])
.controller('ExampleController', ['$scope', '$window', function($scope, $window) {
$scope.greeting = 'Hello, World!';
$scope.doGreeting = function(greeting) {
// This would be a starting point
$window.onload(greeting);
};
}]);
Your markup
<div ng-controller="ExampleController" ng-init="ExampleController.doGreeting()">
</div>
//inside your controller
$scope.$on('$viewContentLoaded', function() {
// write here
// either methods or variables
});
I have a page as follows. The controller is not working. Can someone please suggest me whats wrong?
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml" data-ng-app="demoApp">
<head>
<title>AnjularJs Hello World</title>
</head>
<body data-ng-controller="CustomerController">
<h2>Customers</h2>
<div id="Trial">{{name}}</div>
<script src="Scripts/angular.js"></script>
<script>
(function () {
alert("Inside Self invoking function. This is popping up.");
CustomerController = function ($scope) {
alert("Inside controller. But this is NOT popping up");
$scope.name = 'HeHe';
};
CustomerController.$inject = ['$scope'];
angular.module('demoApp').controller('CustomerController', CustomerController);
}());
</script>
</body>
</html>
Alert inside the controller is not popping. The first alert is popping. Also the div with id="Trial" is not printing the name.
What am I missing?
You never create your demoApp-module. With angular.module(name) you get an already created module, with angular.module(name, dependencies) you set(create) a module. So simply add:
angular.module('demoApp', []);
above the line with angular.module('demoApp') and your cord works just fine:
(function () {
alert("Inside Self invoking function. This is popping up.");
CustomerController = function ($scope) {
alert("Inside controller. But this is NOT popping up");
$scope.name = 'HeHe';
};
CustomerController.$inject = ['$scope'];
angular.module('demoApp', []);
angular.module('demoApp').controller('CustomerController', CustomerController);
}());
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<body ng-app="demoApp" data-ng-controller="CustomerController">
<h2>Customers</h2>
<div id="Trial">{{name}}</div>
</body>
I have a quick question on loading external page with route. I am quite new to AngularJS.
var app = angular.module('app', []);
$routeProvider.when('/list', {
templateUrl: '/list.html'
})
Load up the page, but within the list.html there is controller defined.
list.html:
<script>
app.controller('test', function(){
console.log('test');
});
</script>
<div ng-controller="test">
</div>
The above code will throw me an error as test is undefined function, unless if i place the app.controller('test') to the parent page.
So i can't place controller on external .html files?

You have to create a separate script.js and should load in main html page during execution of main page or during click of the link
index.html
<!DOCTYPE html>
<html ng-app="app">
<head>
<link rel="stylesheet" href="style.css">
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.15/angular.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.0rc1/angular-route.min.js"></script>
<script src="script.js"></script>
<script src="testscript.js"></script>
</head>
<body ng-controller="home">
<h1>Hello Plunker! {{change}}</h1>
Test
<ng-view></ng-view>
</body>
</html>
testscript.js
function test2($scope){
console.log('succeed');
};
script.js
// Code goes here
var app = angular.module('app', ['ngRoute']);
app.controller('home', function($scope){
$scope.change = "change";
$scope.test = function(){
console.log('clicked');
}
});
app.config(function($routeProvider){
$routeProvider.when('/test', {
templateUrl: 'test.html',
controller: function(){
console.log('here');
}
})
});
I know this question has been asked 100s of times but i have yet to succeed in implementing this after reading countless of threads... shame on me.
I know this is a lot of code (sorry). But I just can't find what I'm doing wrong,
So to the problem I want to add something to the list in pat1 then click over to pat2 and see the same list.
Routing;
var routeApp = angular.module('routeApp', ['ngRoute', 'rootMod']);
routeApp.config(['$routeProvider', function($routeProvider) {
$routeProvider.
when('/pat1', {
templateUrl: 'partials/pat1.html',
controller: 'pageOneCont'
}).
when('/pat2', {
templateUrl: 'partials/pat2.html',
controller: 'pageTwoCont'
}).
otherwise({
redirectTo: '/pat1'
});
}]);
Controllers & Service:
var rootMod = angular.module('rootMod', []);
rootMod.controller('pageOneCont', [ 'serv', '$scope', function (serv, $scope) {
'use strict';
// Your controller implementation goes here ...
$scope.handleClick = function ($scope, serv){
var updateFoo = function(){
$scope.foo = serv.foo;
};
aService.registerObserverCallback(updateFoo);
//service now in control of updating foo
};
}]);
rootMod.controller('pageTwoCont', [ 'serv', '$scope', function (serv, $scope) {
'use strict';
// Your controller implementation goes here ...
$scope.handleClick = function ($scope, serv){
var updateFoo = function(){
$scope.foo = serv.foo;
};
aService.registerObserverCallback(updateFoo);
//service now in control of updating foo
};
}]);
/* Service */
rootMod.factory('serv', [ function () {
var observerCallbacks = [];
//register an observer
this.registerObserverCallback = function(callback){
observerCallbacks.push(callback);
};
//call this when you know 'foo' has been changed
var notifyObservers = function(){
angular.forEach(observerCallbacks, function(callback){
callback();
});
};
}]);

JS
Your service is injected as serv in your controllers but you call aService. Use serv instead.
You should use rootMod.service() instead of rootMod.factory() since you are using this and not returning anything in your service function (see this for the difference between factories and services).
There is no serv.foo property. You have to add this.foo = /** something **/; to your service function.
So this should work:
var rootMod = angular.module('rootMod', []);
rootMod.controller('pageOneCont', [ 'serv', '$scope', function (serv, $scope) {
'use strict';
// Your controller implementation goes here ...
$scope.handleClick = function ($scope, serv){
var updateFoo = function(){
$scope.foo = serv.foo;
};
serv.registerObserverCallback(updateFoo);
// service now in control of updating foo
};
}]);
rootMod.controller('pageTwoCont', [ 'serv', '$scope', function (serv, $scope) {
'use strict';
// Your controller implementation goes here ...
$scope.handleClick = function ($scope, serv){
var updateFoo = function(){
$scope.foo = serv.foo;
};
serv.registerObserverCallback(updateFoo);
// service now in control of updating foo
};
}]);
/* Service */
rootMod.service('serv', [ function () {
var observerCallbacks = [];
// call this when you know 'foo' has been changed
var notifyObservers = function(){
angular.forEach(observerCallbacks, function(callback){
callback();
});
};
// initialize foo here
this.foo = '';
// register an observer
this.registerObserverCallback = function(callback){
observerCallbacks.push(callback);
};
}]);
HTML
You put the ng-view container outside of the body. It has to be inside. Also the path to a view starts with #/ so you have to change your links.
<!doctype html>
<html lang="en" ng-app="routeApp">
<head>
<script src="lib/angular/angular.js"></script>
<script src="lib/angular/angular-route.js"></script>
<script src="js/app.js"></script>
<script src="js/controllers.js"></script>
</head>
<body>
<li> ONE </li>
<li> TWO </li>
<!-- SinglePage -->
<div ng-view></div>
</body>
</html>
Each view only needs the content that should be placed inside the ng-view container. So you mustn't make a complete HTML document.
pat1.html
<h1> ONE </h1>
<button ng-click="handleClick"> BROADCAST </button>
<div ng-repeat="item in foo">{{ item }}</div>
pat2.html
<h1> TWO </h1>
<div ng-repeat="item in foo">{{ item }}</div>
