I've the following simple Angular JS trail, which contains the basic CRUD operations:
<html>
<head>
<title>CRUD</title>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.5.7/angular.min.js"></script>
</head>
<body>
<div ng-app>
Simple Expression Evaluator:<br/>
<input ng-model="calculator"/><br/>
{{calculator + "=" + $eval(calculator)}}
</div>
<h3>CRUD - Comments</h3>
<div ng-app="commentapp">
<ul ng-controller="commentController">
<li ng-repeat="user in users">
{{user.name}} wrote "{{user.comment}}"
<br/><a href="#" ng-click="remove(user)">Delete</a>
<a href="#" ng-click="edit(user)">Edit</a>
</li>
<li>
<input id="name" ng-model="current.name" value="{{current.name}}" />
<input id="name" ng-model="current.comment" value="{{current.comment}}" />
</li>
<li>
<button ng-click="save(current)">
Save
</button>
<button ng-click="addNew(current)">
Add New User
</button>
</li>
</ul>
</div>
<script>
var app = angular.module("commentapp", []);
app.controller("commentController", function($scope) {
$scope.users = [{
"name": "Qwe",
"comment": "Great!"
}];
$scope.current = {};
$scope.addNew = function(user) {
$scope.users.push(user);
};
$scope.edit = function(user) {
$scope.current = user;
};
$scope.save = function(user) {
$scope.current = {};
};
$scope.remove = function(user) {
var index = $scope.users.indexOf(user);
$scope.users.splice(index, 1);
};
});
</script>
</body>
</html>
However the output shows:
So, the expression evaluator works perfectly, which means Angular JS is tied up correctly. But the rest of the components don't work at all. Instead of Qwe, I get the expression {{user.name}}. What am I doing wrong here?
