How to dynamically change header based on AngularJS partial view?

I just discovered a nice way to set your page title if you're using routing:

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;
    });
}]);

HTML:

<!DOCTYPE html>
<html ng-app="myApp">
<head>
    <title ng-bind="'myApp &mdash; ' + title">myApp</title>
...

Edit: using the ng-bind attribute instead of curlies {{}} so they don't show on load


Note that you can also set the title directly with javascript, i.e.,

$window.document.title = someTitleYouCreated;

This does not have data binding, but it suffices when putting ng-app in the <html> tag is problematic. (For example, using JSP templates where <head> is defined in exactly one place, yet you have more than one app.)


You could define controller at the <html> level.

 <html ng-app="app" ng-controller="titleCtrl">
   <head>
     <title>{{ Page.title() }}</title>
 ...

You create service: Page and modify from controllers.

myModule.factory('Page', function() {
   var title = 'default';
   return {
     title: function() { return title; },
     setTitle: function(newTitle) { title = newTitle }
   };
});

Inject Page and Call 'Page.setTitle()' from controllers.

Here is the concrete example: http://plnkr.co/edit/0e7T6l


Declaring ng-app on the html element provides root scope for both the head and body.

Therefore in your controller inject $rootScope and set a header property on this:

function Test1Ctrl($rootScope, $scope, $http) { $rootScope.header = "Test 1"; }

function Test2Ctrl($rootScope, $scope, $http) { $rootScope.header = "Test 2"; }

and in your page:

<title ng-bind="header"></title>
