如何根据路由器提供的当前控制器更改控制器范围外显示的标题?基本上,我有调用特定路由时加载的mainMenu控制器。但是,在视图之外,存在部分包括的标题。我想根据当前路线更改标题内的输出。我在下面添加了代码结构:
的index.html
<div ng-include="'partials/header.html'"></div>
<div ng-view></div>
/partials/header.html
<header ng-controller="HeaderCtrl">
<h1>{{ currentTitle }}</h1>
</header>
/partials/main-menu.html
<div ng-controller="MainMenuCtrl">
</div>
路由器
var TaskApp = angular.module('TaskApp', [
'ngRoute',
'taskAppControllers'
]);
TaskApp.config(['$routeProvider',
function($routeProvider){
$routeProvider.
when('/main-menu', {
templateUrl: "partials/main-menu.html",
controller: "MainMenuCtrl"
}).
otherwise({
redirectTo: "/"
});
}]);
控制器:
var taskAppControllers = angular.module('taskAppControllers',[]);
taskAppControllers.controller('TaskAppCtrl',[function(){}]);
taskAppControllers.controller('DesktopCtrl',[function(){}]);
taskAppControllers.controller('MainMenuCtrl', ['$scope','$http',
function($scope, $http){
$http.get('data/main-menu.json?' + Math.random()).success(function(data){
$scope.mainMenuOptions = data;
});
$scope.currentTitle = "Main menu"
}]);
taskAppControllers.controller('HeaderCtrl', ['$scope',
function($scope){
//
}]);
答案 0 :(得分:5)
您可以为每个路线选项添加一个属性,类似于title
when('/main-menu', {
templateUrl: "partials/main-menu.html",
controller: "MainMenuCtrl",
title: 'Main Page'
}).
然后在HeaderCtrl
内放置$routeChangeSuccess(在路由更改成功时触发)事件,然后抓住当前路由对象并从中获取标题并将其设置为currentTitle
范围变量
$scope.$on('$routeChangeSuccess', function(event, current) {
$scope.currentTitle = current.title;
});
