} , false);
}
$scope.getMessage();
}
var IDmodule = angular.module('IDAddon', []).controller('MainCtrl', MainController)
I can confirm that the "message" event is received and the event handler function is called, but the page never gets updated with the message.
Am I missing anything here?

I am trying to make a button that executes a action immediately after he was clicked. But if the mouse is still down after a timeout the action should be repeated as long as the button is down.
In the following code the $interval is working. But somehow the $timeout gets ignored and the interval starts immediately. What am I doing wrong?
angular
.module('myApp', [])
.controller('myController', ($scope, $timeout, $interval) => {
var interval;
var timeout;
let main = $scope;
main.times = 0;
let promise;
let doSomethingOneTime = () => {
$scope.times++;
};
let doSomethingInfinitely = function() {
promise = $interval(function() {
doSomethingOneTime();
}, 100)
};
main.mouseDown = function(action) {
doSomethingOneTime();
$timeout(doSomethingInfinitely, 5000);
};
main.mouseUp = function() {
$interval.cancel(promise);
};
});

The problem is two fold. The first case is that if you mouse up before the timeout delay has finished, the interval promise you set will still be undefined, thus when you call cancel nothing is cancelled. The second problem is if you click the button twice you will lose all reference to the first interval promise. The second click, which creates a second timeout will replace the first interval promise when it finishes. In effect you'll have 2 $intervals executing concurrently, one of which you have no reference to.
Here is a working example.
angular
.module('myApp', [])
.controller('myController', ($scope, $timeout, $interval) => {
var interval;
var timeout;
$scope.times = 0;
$scope.mouseUp = function(){
$timeout.cancel(timeout);
$interval.cancel(interval);
};
let increment = ()=>{
$scope.times++;
};
$scope.mouseDown = function(){
increment();
timeout = $timeout(()=>{
interval = $interval(()=>{
increment();
},100)
}, 1000)
};
});

Attempting to learn angularjs because I need to modify some stuff at work and that is what they are using and I can't upgrade to Angular2+ at the moment. I have the following code where I'm trying to use the $http.get method but getting $http not defined error in the console.
// js code
var app = angular.module('app', []);
app.controller('HelloWorldCtrl', function($scope){
var onUserComplete = function(response){
$scope.user = response.data;
};
$http.get("https://api.github.com/users/robconery")
.then(onUserComplete);
$scope.message = "Hello, AngularJS";
});

You need to pass $http as a dependency to your controller,
app.controller('HelloWorldCtrl', function($scope,$http){
});
DEMO
var app = angular.module('app', []);
app.controller('HelloWorldCtrl', function($scope,$http){
var onUserComplete = function(response){
$scope.user = response.data;
};
$http.get("https://api.github.com/users/robconery")
.then(onUserComplete);
$scope.message = "Hello, AngularJS";

I am trying to make flash messages in my AngularJs app with the use of sachinchoolur's angularjs-flash module.
The flashes work but they don't disappear after the set TimeOut.
I followed the documentation correctly and I made a minimum code in plnkr to demonstrate the problem.
https://plnkr.co/edit/OaLbAjqZDmeWoPxr5uaf?p=preview
app.js
// public/js/app.js
angular.module('myApp', ['ngFlash'
])
.config(['$locationProvider', '$httpProvider', 'FlashProvider',
function($locationProvider, $httpProvider, FlashProvider) {
FlashProvider.setTimeout(5000);
}])
.controller('MainCtrl', function($scope, $rootScope, $http, $location, $window, Flash) {
$scope.test = "test";
$scope.show = function() {
var message = 'Welcome '
var id = Flash.create('success', message, 0, {class: 'custom-class', id: 'custom-id'}, true);
alert("show");
}
});
html template:
<!DOCTYPE html>
<html ng-app="myApp">
<head>
<link data-require="bootstrap#*" data-semver="4.0.5" rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-alpha.6/css/bootstrap.min.css" />
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.6/angular.min.js"></script>
<script type="text/javascript" src="//cdnjs.cloudflare.com/ajax/libs/angular-ui-router/0.2.0/angular-ui-router.js"></script>
<script type="text/javascript" src="//cdnjs.cloudflare.com/ajax/libs/script.js/2.4.0/script.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.0/jquery.min.js"></script>
<script type="text/javascript" src="app.js"></script>
<script type="text/javascript" src="angular-flash.js"></script>
</head>
<body ng-controller="MainCtrl">
<h1>Hello Plunker!</h1>
{{ test }}
<flash-message duration="5000"></flash-message>
<button ng-click="show()">Test</button>
</body>
</html>
According to how to use | angular-flash for Flash.create(...),
Third argument (number, optional) is the duration of showing the flash. 0 to not automatically hide flash (user needs to click the cross on top-right corner).
Hence, I changed your Flash.create function to contain 5000 instead of 0 which was your timeout:
Flash.create('success', message, 5000, {
class: 'custom-class',
id: 'custom-id'
}, true);
And, it works!
Here's working example
See example below and the TODO in the send function : How can I assign the label value in the global send function to dropboxController dropbox.label

<script src="script.js"></script>
<link rel="stylesheet" href="style.css" />
<script type="text/javascript">
window.onload=function() {
$('#AddIn').append("<div ng-app='dropboxApp' ng-controller='dropboxController as dropbox'>{{dropbox.label}}</div>");
angular.module('dropboxApp', [])
.controller('dropboxController', function () {
var dropbox = this;
dropbox.label = "hello angular";
});
angular.bootstrap($('#AddIn'), ['dropboxApp']);
}
function send(label)
{
//TODO assign label value to dropboxController dropbox.label
}
</script>
</head>
<body>
<div id="AddIn"></div>
<button onclick="send('new label');">Send</button>
</body>
</html>
Use angular.element and get scope of specific dom element and apply label to it.
Change dropbox.label to $scope.label and inject $scope in controller because this and $scope are different. Check 'this' vs $scope in AngularJS controllers
Keep in Mind: Here I have used myDiv which has scope for angular and added id in append div line.
It's better to use ng-click instead of onclick if possible.
window.onload = function() {
$('#AddIn').append("<div id='myDiv' ng-app='dropboxApp' ng-controller='dropboxController as dropbox'>{{label}}</div>");
angular.module('dropboxApp', [])
.controller('dropboxController', function($scope) {
var dropbox = this;
$scope.label = "hello angular";
});
angular.bootstrap($('#AddIn'), ['dropboxApp']);
}
function send(label) {
var scope = angular.element($("#myDiv")).scope();
scope.$apply(function() {
scope.label = label;
})
console.log(scope.label);
}

I have just started learning Angular and trying to print some text through angular custom directive. but nothing is getting print. Please help me out. Here is the index.html and script.js file.
angular.module('main', [])
.controller('mainCtrl', function ($scope) {
$scope.name = "firoz";
})
.directive('myDir', function () {
return {
restrict : 'E',
template: '<div>Trying to print this text</div>'
};
});
<!DOCTYPE html>
<html ng-app="main">
<head>
<script data-require="angular.js#1.3.17" data-semver="1.3.17" src="https://code.angularjs.org/1.3.17/angular.js"></script>
<link rel="stylesheet" href="style.css" />
<script src="script.js"></script>
</head>
<body ng-controller="mainCtrl">
<mydir></mydir>
</body>
</html>
Here is the Plunker link : http://plnkr.co/edit/ub9Ch34OtckzQuCI9sDk?p=preview
You need to hyphenate anywhere that has a capital when used in the directive, like:
<my-dir></my-dir>
The correct Angular syntax is:
<my-dir></my-dir>
angular.module('main', [])
.controller('mainCtrl', function ($scope) {
$scope.name = "firoz";
})
.directive('myDir', function () {
return {
restrict : 'E',
template: '<div>Trying to print this text</div>'
};
});
