How Can I Dynamically Update Page

Dynamically Modifying Headers in AngularJS Partial Views

In AngularJS, managing page headers and titles across different partial views can present a challenge. To address this, various approaches have been explored, including leveraging view controllers and shared services. However, a simpler and more efficient solution has emerged for scenarios involving routing.

Solution Using Routing

The provided code demonstrates how to seamlessly update your page title and h1 header when changing between AngularJS partial views:

<code class="javascript">var myApp = angular.module('myApp', ['ngResource']);

myApp.config(
    ['$routeProvider', function($routeProvider) {
        $routeProvider.when('/', {
            title: 'Home',
            templateUrl: '/Assets/Views/Home.html',
            controller: 'HomeController'
        });
        $routeProvider.when('/Product/:id', {
            title: 'Product',
            templateUrl: '/Assets/Views/Product.html',
            controller: 'ProductController'
        });
    }]);

myApp.run(['$rootScope', function($rootScope) {
    $rootScope.$on('$routeChangeSuccess', function (event, current, previous) {
        $rootScope.title = current.$$route.title;
    });
}]);</code>

Copy after login

This solution utilizes the $routeChangeSuccess event, which triggers whenever a successful route change occurs. Within this event listener, you can retrieve the title from the current route configuration and assign it to the $rootScope.title property.

HTML:

In your HTML, you can then bind the page title and h1 header to the $rootScope.title property:

<code class="html"><head>
    <title ng-bind="'myApp &amp;mdash; ' + title">myApp</title>
...
<body>
<h1 ng-bind="title"></h1></code>

Copy after login

By leveraging the ng-bind attribute, the page title and h1 header will automatically update when the route changes. This solution provides a clean and efficient way to dynamically manage your header information based on the current partial view.
