UI-Router 多个视图单个控制器不起作用 [英] UI-Router Multiple Views Single Controller not work
问题描述
我想使用一个在视图中定义的控制器，但是 $scope 没有定义任何东西.有没有办法做到这一点?请分享一个简单的例子以便理解.
I would like to use one controller defined in views, but the $scope does not define anything. Is there a way to do this? Please share a simple example in order to understand.
我有这个 index.html
I have this index.html
<body ng-app="ehc">
<h1>{{home}}+{{a}}+{{b}}</h1>
<ion-side-menus enable-menu-with-back-views="false" delegate-handle="left">
<!-- Left menu -->
<ion-side-menu side="left" is-enabled="true">
<ion-header-bar class="bar-stable">AAA</ion-header-bar>
<ion-content>
<div class="list">
<div class="item item-divider">
Candy Bars
</div>
</div>
</ion-content>
</ion-side-menu>
<ion-side-menu-content edge-drag-threshold="true" drag-content="true">
<!-- Main content, usually <ion-nav-view> -->
<ion-nav-bar class="bar-positive" >
<ion-nav-title>
<h2>hello world title *{{home}}*</h2>
</ion-nav-title>
<ion-nav-buttons side="left">
<button class="button button-icon button-clear ion-navicon" menu-toggle="left"></button>
</ion-nav-buttons>
</ion-nav-bar>
<ion-view>
<ion-content class="has-header">
<div class="row">
<div class="col-50">
<div ui-view="a"></div>
</div>
<div class="col-50">
<div ui-view="b"></div>
</div>
</div>
</ion-content>
</ion-view>
</ion-side-menu-content>
<script type="text/ng-template" id="templates/a.html">
<ion-view>
<ion-content class="has-header">
**{{a}}**
</ion-content>
</ion-view>
</script>
<script type="text/ng-template" id="templates/b.html">
<ion-view>
<ion-content class="has-header">
**{{b}}**
</ion-content>
</ion-view>
</script>
</body>
<script src="js/app.js"></script>
这是我的模型定义app.js
var app = angular.module("ehc", ["ionic"])
.config(function ($urlRouterProvider, $stateProvider) {
$urlRouterProvider.otherwise('/');
$stateProvider.state('Home', {
url: '/',
controller: "HomeCtrl",
//template:"<ion-header-bar></ion-header-bar><ion-content><h1>hello dal AngularJs</h1></ion-content>",
views: {
"a": {
templateUrl: 'templates/a.html'
},
"b": {
templateUrl: 'templates/b.html'
}
}
});
}).controller("HomeCtrl", ["$scope", "$ionicSideMenuDelegate",
"$routeParams", "config", "$q", "$http"], function ($scope, $ionicSideMenuDelegate, $routeParams, config, $q, $http) {
$scope.toggleLeft = function () {
$ionicSideMenuDelegate.toggleLeft();
};
//carico le lingue e il menu
console.log("AAAAAAAAAAAA");
$scope.home = "Pippo";
$scope.a="XAX";
$scope.b="XBX";
})
console 是空的，也是 html 模板中的范围.如果您有解决方案，请使用非常简单的示例.
console is empty and also the scope in html template. Please if you have the solution, use very simple example.

推荐答案
非常相似的问题:为什么控制器在 UI-router 中不起作用angularjs的?
这里的重点是:
Controller 永远属于 View，从不属于 state.
Controller always belongs to View, never to state.
换句话说，要使用相同类型的控制器(但每个视图有两个实例)，我们必须进行这种声明:
Other words, to use same type of controller (but two instances for each view), we have to do that kind of declaration:
$stateProvider.state('Home', {
url: '/',
// instead of this
//controller: "HomeCtrl",
views: {
"a": {
templateUrl: 'templates/a.html',
controller: "HomeCtrl", // we need this
},
"b": {
templateUrl: 'templates/b.html',
controller: "HomeCtrl", // and also this
}
}
});
如果我们想在多个视图之间共享一些东西，我们需要不同于同一个控制器"的技术.见:
In case, we want to share some stuff among many views, we need different technique than "same controller". See:
另一个见解，可以在这里介绍:
Another insight, could be covered here:
包括打字稿在内，有详细的描述和示例，所有视图/状态如何针对一些常见的 RootModel
And including typescript, there is a detailed description and example how all views/states could target some common RootModel
