I am pretty new in angular/js development so now i stacked with this.
When I add ng-controller="HeaderController" to my HTML code it cant load Angular. If you remove this everything is fine. Why that happened? Thanks for any help and sorry for bad English :)
Code:
(function() {
var app = angular.module ('FunStuff',[]);
app.controller ('TextController',['$scope',function($scope){
$scope.stuff = [];
$scope.add = function(){
$scope.stuff.push ($scope.name);
}
}]);
app.controller ('HeaderController'['$scope',function($scope){
$scope.textClass = '';
$scope.changeClrClss = function(name){
$scope.ClrClss = name;
}
}]);
})();
<!DOCTYPE html>
<html ng-app ="FunStuff">
<head>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.32/angular.min.js"></script>
<link rel="stylesheet" type="text/css" href="style.css">

<meta charset="utf-8">

<body >
<header ng-class = "ColorClass" ng-controller="HeaderController">
<h1>$~/Path_To_Js/</h1>
<button class="changeColorBtn" ng-click="changeColorClass('white')">

</button>
</header>
<div class="wrapper" >
<article ng-controller = "TextController">
<p>There will be some information</p>
<form ng-submit="add()">
<input ng-model="name"><button>Add</button>
</form>
<ul class="buttons" ng-repeat= "n in stuff track by $index">
<li>{{n}}</li>
</ul>
</article>
</div>
<script type="text/javascript" src="index.js"></script>
</body>
</html>
As your error says, You are missing , after the header controller,
app.controller ('HeaderController',['$scope',function($scope){
$scope.textClass = '';
$scope.changeClrClss = function(name){
$scope.ClrClss = name;
}
}]);
DEMO
var app = angular.module ('FunStuff',[]);
app.controller ('TextController',['$scope',function($scope){
$scope.stuff = [];
$scope.add = function(){
$scope.stuff.push ($scope.name);
}
}]);
app.controller ('HeaderController',['$scope',function($scope){
$scope.textClass = '';
$scope.changeClrClss = function(name){
$scope.ClrClss = name;

When i added ng-controller to my index.html, the expression show up as {{name || "Hello"}} and {{ age || "my friend" }}. After i removed the ng-controller, expressions aslo cannot work.
it is the controller.js
var PersonCtrl = function($scope){
$scope.name = 'sky';
$scope.age = 18;
$scope.$watch('name', function(){
console.log($scope.name);
});
$scope.$watch('age', function(){
if($scope.age < 18){
console.error('not correct');
}
});
};
it is the index.html
<!DOCTYPE html>
<!-- whole page is applied in AngularJS -->
<html ng-app>

Change your html tag to
<html ng-app="myApp">
controller.js :
// Define the Module. Only once in your code.
var myApp = angular.module('myApp', []);
// Define a controller for you module.
myApp.controller('PersonCtrl', ['$scope', function ($scope) {
$scope.name = 'sky';
$scope.age = 18;
$scope.$watch('name', function () {
console.log($scope.name);
});
$scope.$watch('age', function () {
if ($scope.age < 18) {
console.error('not correct');
}
});
}]);
Here is the code in concern:
<div ng-app="">
https://www.facebook.com/sharer/sharer.php?u={{$location.absUrl()}}
https://www.facebook.com/sharer/sharer.php?u={{$location.$$url}}
https://www.facebook.com/sharer/sharer.php?u={{$location.$$path}}
</div>
We need the value of the u parameter to be current page.
Where are we wrong?
You cannot do that in HTML, alternatively you can get the current location like this,
Assign the curren location to a scope variable,
$scope.a = window.location.href;
Then in HTML,
<br>Link = <a ng-href="https://www.facebook.com/sharer/sharer.php?u={{a }}" target="_blank">facebook</a>

The property which are present of $scope variable those are only available to use on HTML as binding. So $location service you have to expose on $scope
//inject $location to controller before use it.
$scope.$location = $location;
I must make a website. When you press an IMG it adds the template from the directive to another div.
In detail, I have 3 imgs on my website. Hamburger, Cola and Crips. When you press one of them it adds it to the Order List.
HTML code:
<!DOCTYPE HTML>
<html ng-app="myApp">
<head>
<script src="scripts/angular.min.js"></script>
<meta http-equiv="content-type" content="text/html; charset=utf-8">
<link rel="Stylesheet" type="text/css" href="styles/style.css">
<title>Food Center</title>
<script src="scripts/skrypt.js"></script>
</head>
<body>
<h1 class="ladne"><center>Food Center</center></h1>
<div class="d1" ng-controller="myCtrl" myDir1>
<img src="styles/img/cola.gif"></img>
<img src="styles/img/fryt.gif"></img>
<img src="styles/img/ham.gif"></img>
<br>
<div class="zam" >
Date of order: {{data | date:'yyyy-MM-dd'}}
<br>
Your Order:
</div>
</div>
</body>
</html>
Controller code:
var myApp = angular.module('myApp', []);
myApp.controller('myCtrl', function($scope) {
$scope.data = new Date();
$scope.hamburger ={
name: 'Hambureger',
}
$scope.frytki = {
name: 'Frytki',
}
$scope.cola = {
name: 'Coca-Cola',
}
});
myApp.directive('dir1', function () {
return {
restrict: 'A',
template: '<br>{{hamburger.nazwa}}'
};
});
I really don't understand these directives. Would be nice if you can help me.
Right I've got a really dumb one for you, and I've been looking at this code all day with no result.
I have a simple textbox which goes through a controller and updates a variable inside a service (The service will eventually fetch/update data from somewhere else).
At the moment, I am able to retrieve the variable value all the way to the view and it works, but the textbox is unable to update the variable inside the service in order to then display the new variable value in the view again....
I really appreciate any help and hope I have made sense!!!

You need to be binding to name and not nameVal on your input
Then just pass that in your setName call, i don't think the rest of the code is needed in there, you can get rid of the nameValue var too.
this.submitName = function() {
dataService.setName(this.name);
};
The nameValue var is local to the controller and not available on the $scope to bind to your view, so even though you were changing it, the view didn't know about it as it couldn't see that var.
I add ui-bootstrap-tpls-0.12.0.js to my project and us accordion and now I wanna use pagination but i get this error
ngModelCtrl.$render is not a function
here is my code
<div ng-controller="paginationCtrl">
<pagination num-pages="noOfPages" current-page="currentPage" on-select-page="pageChanged(page)"></pagination>
</div>
i add ui.bootstrap
angular.module("boors", ['ui.router','ui.bootstrap','angularUtils.directives.uiBreadcrumbs','ngAnimate','truncate']);
and in my script tag i have
<script src="<?=$this->assetsBase?>/js/lib/ui-bootstrap-tpls-0.12.0.js"></script>
accordion works fine but pagination doesnt work
Take a closer look at the documentation for the pagination control.
http://angular-ui.github.io/bootstrap/#/pagination
I guess you're at least missing the ng-model attribute, otherwise your pagination doesn't know where to look for the current value. Guess thats what you meant with current-page.
Use version 10, Here is the sample of pagination
