Troubleshooting data binding issues in AngularJS tutorial

I'm having some trouble with a basic example. I have two files, index.html and main.js, both located in the same folder:

<!DOCTYPE html>
<html>
<head>
        <title> AngularJS Tutorials </title>
        <link rel="stylesheet" href="css/foundation.min.css">
        <script src="main.js"></script>
</head>
<body>

<div ng-app="myApp">
    <div ng-controller="FirstCtrl">
        <h1>{{data.message}}</h1>
    </div>
</div>

<script type="text/javascript" src="js/angular.min.js"></script>
</body>
</html>

Main.js contains the following code:

function FirstCtrl($scope) {
    $scope.data = {message: "Hello"};
}

But when I view my page, all I see is this:

{{data.message}}

Answer №1

To successfully integrate the controller into the angular module, utilize the controller function to incorporate the JavaScript function for your controller.

var SecondCtrl = function SecondCtrl($scope) {
    $scope.data = {message: "Greetings"};
};

angular.module("myApp", []).controller("SecondCtrl", SecondCtrl);

If the angular module has already been declared on another part of the page, simply follow this format.

angular.module("myApp").controller("SecondCtrl", SecondCtrl);
