Angular ui-router : Parent &子视图 [英] Angular ui-router : Parent & Child Views
问题描述
我想建立一个具有以下结构的站点 header-view, main-view, footer-view .所以我定义了一个包含标头 & 的根路由.页脚.root 的子级将成为我的所有站点.在这些站点中，我将拥有更多嵌套视图.
I want to build a site with the following structure header-view, main-view, footer-view . So I defined a root route which contains the header & footer. Children of root will be all my sites.Within these sites I will have more nested views.
在下面的代码中，它确实显示了页眉，但不显示页脚 &主要观点.一旦我删除了父继承，它就会显示主视图而不是标题 &页脚.
In the code below it does show the header, but not the footer & the main view. As soon as I remove the parent inheritance, it shows the main view but not the header & the footer.
HTML
<body ng-app="App">
<header ui-view="header"></header>
<main ui-view></ui-view>
<footer ui-view="footer"></footer>
</body>
JS
module.config(function($urlRouterProvider, $stateProvider) {
$urlRouterProvider.otherwise('/home');
$stateProvider
.state('root', {
abstract: true,
views: {
'@': {
controller: 'RootCtrl',
controllerAs: 'rootCtrl'
},
'header@': {
templateUrl: 'modules/header/header.html',
controller: 'HeaderCtrl',
controllerAs: 'headerCtrl'
},
'footer@': {
templateUrl: 'modules/footer/footer.html',
controller: 'FooterCtrl',
controllerAs: 'footerCtrl'
}
}
})
.state('root.home',{
parent:'root',
url:'',
templateUrl:'modules/home/home.html',
controller: 'HomeController',
controllerAs:'homeCtrl'
});
});

UI-Router 如何为视图找到目标/锚点的逻辑是:总是尝试将 child 插入 parent.如果不可能，则使用绝对命名.见:
The UI-Router logic how to find a target/anchor for a view is: always try insert child into parent. If not possible, then use absolute naming. see:
所以我改变的是，父未命名视图现在包含子视图的目标/锚点 - 未命名视图 <ui-view/>:
So what I changed, is, that the parent unnamed view is now containing a target/anchor for a child - unnamed view <ui-view />:
.state('root', {
abstract: true,
views: {
'@': {
template: '<ui-view />', // NEW line, with a target for a child
controller: 'RootCtrl',
controllerAs: 'rootCtrl'
},
....
另外，因为我们说，默认网址是
Also, because we say, that the default url is
$urlRouterProvider.otherwise('/home');
我们必须有这样的状态:
we have to have such state:
.state('root.home',{
parent:'root',
url:'/home', // this is the otherwise, to have something on a start up
在此处
另一种使用 plunker 的方法，可以是将根视图定位到孩子:
Another approach with a plunker here, could be to target the root view in the child:
.state('root.home',{
parent:'root',
url:'/home',
views: {
'@': {
templateUrl:'home.html',
controller: 'HomeController',
controllerAs:'homeCtrl'
}
},
在这种情况下，父状态不必具有 <ui-view/> - 我们以 root 为目标，但我们不会继承任何东西......为什么会这样?请参阅此链接:
In this case, the parent state does not have to have <ui-view /> - we target root, but we won't be inheriting anything... Why is that? See this link:
