使用链接修改ng-switch

Question

如何使用链接来触发ng开关?

我当前的html:

<ul class="nav nav-list bs-docs-sidenav affix sidenav">
    <li><a href="#" ng-click="page='resources'">Resources</a></li>
    <li><a href="#" ng-click="page='users'">Users</a></li>
</ul>
<div ng-switch on="page">
    <div ng-switch-when="resources">
        <h1>resources Div</h1>
    </div>
    <div ng-switch-when="users">
        <h1>Users</h1>
    </div>
    <div ng-switch-default>
        <h1>Default</h1>
    </div>
</div>

我的控制器:

function Ctrl($scope) {
    $scope.page = 'users';
}

我错过了什么?

Answer 1

我偶然发现了一个类似的问题，并通过在作用域上使用对象而不是属性来解决它，以便值不会被ng-switch指令覆盖。

所询问的问题与此解决方案之间的区别在于，我从ng-switch范围内更改了页面值。

在控制器中声明nav对象

$scope.nav = {
                 page : 1
             }

HTML

<div ng-switch="nav.page">
<div ng-switch-when="1">
    First page
    <a href="#" ng-click="nav.page=2">Resources</a>
</div>
<div ng-switch-when="2">
    Second page
    <a href="#" ng-click="nav.page=3">Resources</a>
</div>
<div ng-switch-when="2">
    Third page
</div>

必须将控制器绑定到顶层元素。这是小提琴

HTML:

<div ng-app ng-controller="Ctrl">
     <ul class="nav nav-list bs-docs-sidenav affix sidenav">
         <li><a href="#" ng-click="page='resources'">Resources</a></li>
         <li><a href="#" ng-click="page='users'">Users</a></li>
     </ul>
     <div ng-switch on="page">
        <div ng-switch-when="resources">
           <h1>resources Div</h1>
        </div>
        <div ng-switch-when="users">
           <h1>Users</h1>
        </div>
        <div ng-switch-default>
           <h1>Default</h1>
        </div>
     </div>
</div>
