I am using ng-view to include AngularJS partial views, and I want to update the page title and h1 header tags based on the included view. These are out of scope of the parti

    When I had to solve this, I couldn't place the ng-app on the page's html tag, so I solved it with a service:

    angular.module('myapp.common').factory('pageInfo', function ($document) {
    
        // Public API
        return {
            // Set page <title> tag. Both parameters are optional.
            setTitle: function (title, hideTextLogo) {
                var defaultTitle = "My App - and my app's cool tagline";
                var newTitle = (title ? title : defaultTitle) + (hideTextLogo ? '' : ' - My App')
                $document[0].title = newTitle;
            }
        };
    
    });

    Thanks to tosh shimayama for his solution.
    I thought it was not so clean to put a service straight into the $scope, so here's my slight variation on that: http://plnkr.co/edit/QJbuZZnZEDOBcYrJXWWs

    The controller (that in original answer seemed to me a little bit too dumb) creates an ActionBar object, and this one is stuffed into $scope.
    The object is responsible for actually querying the service. It also hides from the $scope the call to set the template URL, which instead is available to other controllers to set the URL.

    A clean way that allow dynamically setting title or meta description. In example I use ui-router but you can use ngRoute in same way.

    var myApp = angular.module('myApp', ['ui.router'])
    
    myApp.config(
        ['$stateProvider', function($stateProvider) {
            $stateProvider.state('product', {
                url: '/product/{id}',
                templateUrl: 'views/product.html',
                resolve: {
                    meta: ['$rootScope', '$stateParams', function ($rootScope, $stateParams) {
                        var title = "Product " + $stateParams.id,
                            description = "Product " + $stateParams.id;
                        $rootScope.meta = {title: title, description: description};
                    }]
    
                    // Or using server side title and description
                    meta: ['$rootScope', '$stateParams', '$http', function ($rootScope, $stateParams, $http) {
                        return $http({method: 'GET', url: 'api/product/ + $stateParams.id'})
                            .then (function (product) {
                                $rootScope.meta = {title: product.title, description: product.description};
                            });
                    }]
    
                }
                controller: 'ProductController'
            });
        }]);
    

    HTML:

    <!DOCTYPE html>
    <html ng-app="myApp">
    <head>
        <title ng-bind="meta.title + ' | My App'">myApp</title>
    ...

    The better and dynamic solution I have found is to use $watch to trace the variable changes and then update the title.

    Alternatively, if you are using ui-router:

    index.html

    <!DOCTYPE html>
    <html ng-app="myApp">
    <head>
        <title ng-bind="$state.current.data.title || 'App'">App</title>
    

    Routing

    $stateProvider
      .state('home', {
          url: '/',
          templateUrl: 'views/home.html',
          data: {
            title: 'Welcome Home.'
          }
      }

    If you don't have control over title element (like asp.net web form) here is some thing you can use

    var app = angular.module("myApp")
        .config(function ($routeProvider) {
                    $routeProvider.when('/', {
                                                title: 'My Page Title',
                                                controller: 'MyController',
                                                templateUrl: 'view/myView.html'
                                            })
                                .otherwise({ redirectTo: '/' });
        })
        .run(function ($rootScope) {
            $rootScope.$on("$routeChangeSuccess", function (event, currentRoute, previousRoute) {
                document.title = currentRoute.title;
            });
        });
