angularjs - ui-router 默认子状态不起作用

Question

我正在测试 UI-Router嵌套状态，但我无法在父/子场景中设置默认状态，请帮助。

图书馆:

Angular 1.3.15

ui 路由器:0.2.15

导航路径:

/ - home
/settings - parent state/page
/settings.default - child 1
/settings.mail - child 2
/settings.phone - child 3

预期行为:

导航到 /settings 时，应该触发/加载默认的子“常规”状态/页面

实际行为:

如果我设置 'settings' state 'abstrat: true'，就会出现错误:

Error: Cannot transition to abstract state 'settings'
    at Object.transitionTo (angular-ui-router.js:3143)
    at Object.go (angular-ui-router.js:3068)
    at angular-ui-router.js:4181
    at angular.js:16299
    at completeOutstandingRequest (angular.js:4924)
    at angular.js:5312

如果我删除 'abstrat: true'，则没有错误，但是当我导航到/settings 时，默认子状态/页面 - 一般状态未触发，settings.html 显示但未加载

app.js:

angular.module('test',['ui.router','sails.io'])     //config routing
.config(['$stateProvider','$urlRouterProvider','$locationProvider',
        function($stateProvider,$urlRouterProvider,$locationProvider) {

  $urlRouterProvider.otherwise('/');    
  $locationProvider.html5Mode(true);

  $stateProvider
    .state('home', {
        url: '/',
        templateUrl: 'views/index.html',
        controller: 'IndexController'
    })
    .state('settings', {
        abstract: true,
        url: '/settings',
        templateUrl: 'views/settings.html',
        controller: 'SettingsController'
    })
    .state('settings.general', {
        url: '',
        templateUrl: 'views/settings/general.html',
        controller: 'SettingsController'
    })
    .state('settings.mail', {
        url: '/mail',
        templateUrl: 'views/settings/mail.html',
        controller: 'SettingsController'
    })
    .state('settings.phone', {
        url: '/phone',
        templateUrl: 'views/settings/phone.html',
        controller: 'SettingsController'
    });
}]);

View /settings.html

<div class="container">
  <div class="row">
    <div class="col-md-3">
      <ul class="list-group">
        <li class="list-group-item"><a ui-sref=".general">General</a></li>
        <li class="list-group-item"><a ui-sref=".phone">Phone</a></li>
        <li class="list-group-item"><a ui-sref=".mail">Mail</a></li>
      </ul>
    </div>
    <div class="col-md-9">
      <div ui-view></div>
    </div>
  </div>
</div>

有a working plunker

这会起作用，但仅适用于 url导航，即 href :

  <a href="/settings"> // will work

但这不会 - 我们不能去 abstract 状态:

  <a ui-sref="settings">settings</a>

但基于这个问答:

Redirect a state to default substate with UI-Router in AngularJS

我们可以像这样删除抽象并创建默认状态处理。有 updated plunker

// redirection engine
app.run(['$rootScope', '$state', function($rootScope, $state) {

    $rootScope.$on('$stateChangeStart', function(evt, to, params) {
      if (to.redirectTo) {
        evt.preventDefault();
        $state.go(to.redirectTo, params)
      }
    });
}]);

父级统计调整:

.state('settings', {
    //abstract: true,
    redirectTo: 'settings.general',
    url: '/settings',
    ...
