Here is my very simple code:
<!DOCTYPE html>
<html ng-app="myApp">
<head>
<meta charset="utf-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<!--<script src="https://cdnjs.cloudflare.com/ajax/libs/angular.js/1.5.8/angular.js"></script> -->
<script src="https://cdnjs.cloudflare.com/ajax/libs/angular.js/1.6.1/angular.min.js"></script>
</head>
<body>
<t-component test="test">
<div >
{{test}} John
</div>
</t-component>
<script>
angular.module('myApp', []).
component('tComponent', {
bindings: {
test: '='
},
controller: function() {
var self = this;
self.test='Hello';
}
});
</script>
</body>
</html>
I am getting Hello John only when using Angular 1.5.8. What do I have to do as to make the above to work with Angular 1.6.1? What am I missing?
I have this code working like that:
<t-component test="'test'"></t-component>
<script>
angular.module('myApp', []).
component('tComponent', {
template:'{{vm.test}} John',
bindings: {
test: '<'
},
controller: function() {
var self = this;
self.$onInit = function(){
// self.test ='hello'; //if you don`t want to use binding
}
},
controllerAs: 'vm'
});
</script>
<body>
<t-component test="'Hello'"></t-component>
<script>
angular.module('myApp', []).
component('tComponent', {
template: `
{{$ctrl.test}} John
`,
bindings: {
test: '='
},
controller: function() {
}
});
</script>
</body>
Then in controller you can change value of binding.
self.$onInit = function(){
self.test ='I am changed';
}

Referring to the index.html below, how should I pass person into the DashboardController using one-way binding? (That's what I'll need to build from.) When I get it right, index.html should render:
Dashboard person = Mike
Thanks for any suggestions.
<!doctype html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Dashboard</title>
<script src="https://code.angularjs.org/1.8.0/angular.min.js"></script>
<script>
(function (angular) {
'use strict';
angular.module('dashboardApp', []);
})(window.angular);
(function (angular) {
'use strict';
function DashboardController($scope, $element, $attrs) {
var ctrl = this;
ctrl.userid = "Mike";
}
angular.module('dashboardApp').component('dashboard', {
template: "<p>Dashboard person = {{$ctrl.person}}</p>",
controller: DashboardController,
bindings: {
person: '<'
}
});
})(window.angular);
</script>
</head>
<body ng-app="dashboardApp">
<dashboard person="$ctrl.userid"></dashboard>
</body>
</html>
My code:
<html ng-app="myApp">
<head>
<script src="https://cdnjs.cloudflare.com/ajax/libs/angular.js/1.6.1/angular.min.js"></script>
<script src="js/components/appComponent.js"></script>
</head>
<body>
<foo callback="$ctrl.myCallback()"></foo>
</body>
</html>
appComponent.js
(function(){
'use strict';
var app = angular.module('myApp',[]);
app.component('foo', {
bindings: {
callback: '&'
},
templateUrl: '/js/components/appComponent.html',
controller: function () {
this.callback=function(){
console.log('Hello!');
}
}
});
})();
appComponent.html
<div ng-click="$ctrl.myCallback()">
Press me!
</div>
Why ng-click does not trigger $ctrl.callback()? Moreover, what callback="$ctrl.myCallback()" is supposed to do? I am afraid I have misunderstood its concept.
I followed this link https://developers.google.com/identity/sign-in/web/sign-in to get Google Signin on Angular-based website.
I have seen some weird behavior. The signin button sometimes show but not always. When I refresh a page, only 1 in 5 refreshes, the button appears.
I tried in Chrome and Safari and both has same behavior.
Code:
index.html
<script src="https://apis.google.com/js/platform.js" async defer></script>
<meta name="google-signin-client_id" content="my_client_id">
login.html
<div class="g-signin2" data-onsuccess="onSignIn"></div>
login.js
angular.module('app').controller('LoginCtrl', function($scope) {
window.onSignIn = function(googleUser) {
// Get some info
}
});
My guess is that the platform.js script waits for the DOM-ready event and then looks for your div with the "g-signin2"-class. Though, in Angularjs things work a little different. The reason that it works sometimes, is because sometimes your div has been rendered by Angular and sometimes is hasn't been rendered before the Dom-ready event.
There's documentation on how to get the same result with your own javascript.
I made an example that follows your routing.
<!doctype html>
<html lang="en" ng-app="app">
<head>
<meta charset="UTF-8">
<title>Document</title>
</head>
<body>
<div ng-view></div>
<script src="https://apis.google.com/js/platform.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.6/angular.min.js"></script>
<script src="https://code.angularjs.org/1.4.6/angular-route.min.js"></script>
<script>
angular.module('app',['ngRoute'])
.config(['$routeProvider',function($routeProvider){
$routeProvider
.when('/log-in', {
template: '<button ng-click="logInCtrl.onLogInButtonClick()">Log In</button>',
controller: 'LogInController',
controllerAs: 'logInCtrl'
}).otherwise({
redirectTo:'/log-in'
});
}])
.controller('LogInController',function(){
var self = this; //to be able to reference to it in a callback, you could use $scope instead
gapi.load('auth2', function() {//load in the auth2 api's, without it gapi.auth2 will be undefined
gapi.auth2.init(
{
client_id: 'CLIENT_ID.apps.googleusercontent.com'
}
);
var GoogleAuth = gapi.auth2.getAuthInstance();//get's a GoogleAuth instance with your client-id, needs to be called after gapi.auth2.init
self.onLogInButtonClick=function(){//add a function to the controller so ng-click can bind to it
GoogleAuth.signIn().then(function(response){//request to sign in
console.log(response);
});
};
});
});
</script>
</body>
</html>
Or as a directive:
<!doctype html>
<html lang="en" ng-app="app" ng-controller="MainController">
<head>
<meta charset="UTF-8">
<title>Document</title>
</head>
<body>
<google-sign-in-button on-sign-in="onSignIn(response)" g-client-id="CLIENTID.apps.googleusercontent.com"></google-sign-in-button>
<script src="https://apis.google.com/js/platform.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.6/angular.min.js"></script>
<script>
angular.module('app',[])
.controller('MainController',['$scope', function ($scope) {
$scope.onSignIn=function(response){
console.log(response);
}
}])
.directive('googleSignInButton',function(){
return {
scope:{
gClientId:'#',
callback: '&onSignIn'
},
template: '<button ng-click="onSignInButtonClick()">Sign in</button>',
controller: ['$scope','$attrs',function($scope, $attrs){
gapi.load('auth2', function() {//load in the auth2 api's, without it gapi.auth2 will be undefined
gapi.auth2.init(
{
client_id: $attrs.gClientId
}
);
var GoogleAuth = gapi.auth2.getAuthInstance();//get's a GoogleAuth instance with your client-id, needs to be called after gapi.auth2.init
$scope.onSignInButtonClick=function(){//add a function to the controller so ng-click can bind to it
GoogleAuth.signIn().then(function(response){//request to sign in
$scope.callback({response:response});
});
};
});
}]
};
});
</script>
</body>
</html>
After writing the previous examples I found a better and easier way to implement it. With this code you inherit the same button as you normally would.
<!doctype html>
<html lang="en" ng-app="app" ng-controller="MainController">
<head>
<meta charset="UTF-8">
<title>Document</title>
<meta name="google-signin-client_id" content="CLIENTID.apps.googleusercontent.com">
</head>
<body>
<google-sign-in-button button-id="uniqueid" options="options"></google-sign-in-button>
<script src="https://apis.google.com/js/platform.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.6/angular.min.js"></script>
<script>
angular.module('app', [])
.controller('MainController', ['$scope',
function($scope) {
//for more options visit https://developers.google.com/identity/sign-in/web/reference#gapisignin2renderwzxhzdk114idwzxhzdk115_wzxhzdk116optionswzxhzdk117
$scope.options = {
'onsuccess': function(response) {
console.log(response);
}
}
}
])
.directive('googleSignInButton', function() {
return {
scope: {
buttonId: '#',
options: '&'
},
template: '<div></div>',
link: function(scope, element, attrs) {
var div = element.find('div')[0];
div.id = attrs.buttonId;
gapi.signin2.render(div.id, scope.options()); //render a google button, first argument is an id, second options
}
};
});
</script>
</body>
</html>
I found another way to solve the problem a liitle bit simply.
The explanation from #sniel is perfect but I will let you know more simple solution.
you can use below sample code very simiraliry with using $watch
https://developers.google.com/identity/sign-in/web/build-button
<!-- html part -->
<div id="signInButton"></div>
//gapi is Asynchronously loaded so you need to watch
$scope.$watch('gapi', function(newValue,oldVale){
if(newValue !== oldVale){
if(gapi){
gapi.signin2.render('signInButton',
{
'onsuccess': $scope.onSuccess,
'onfailure': $scope.onFailure,
'scope':'https://www.googleapis.com/auth/plus.login'
}
);
}
}
});
Is there any way to broadcast from $rootScope to modal window $scope?
My $rootScope is ApplicationController and I'm listening in there to socket.io event. When I handle this event I want to $broadcast to ChatController (modal window) $scope (which might be already opened so resolve won't help me here).
A quick example to demonstrate this issue:

setTimeout(function() {
console.log('broadcasting event');
$scope.$broadcast('someEvent', 'broadcasted value');
}, 3000);
};
});
app.controller("NotModalController", function($scope) {
$scope.fields = {

$scope.$on('someEvent', function(event, args) {
$scope.fields.field1 = args;

Think you should use $rootScope.$broadcast instead $scope.$broadcast
I am loading a partial in Angular dependant on the route of the URL.
When I load the partial it loads, and responds to the Controllers functions. However I have a directive which has a watcher. This does not work when I use the
It works fine when I load the HTML inside the main page. I have a Plunker of this here
http://plnkr.co/edit/DK33pIrp0HyhUOjwm5X2?p=preview
Essentially clicking "hello" should change the $scope.origin and the watcher should then fire its event. It does not.

<button ng-click="clicked()">hello</button>
how can I get this working?
edit: I have just made this pure JS and not coffeescript.
Thanks so all who helped me find the issue.
This can be done by setting the
<button ng-click="clicked()">hello</button>
to
<button ng-click="$parent.clicked()">hello</button>
This is because the ng-view will be a child. This simple fix is now working.
