我在实现粘性选项卡时遇到问题,其中每个选项卡都可以使用 ui-router-tabs 和 ui-router-extras 有多个子状态。

  1. 当我打开一个状态,移动到另一个状态,然后返回到第一个状态时,相应的控制器正在重新初始化(尽管 ui-router-extras 调试输出显示它重新激活了该状态)

  2. 当我打开同一个选项卡的另一个状态(兄弟状态)时,调试输出、html 模板的 url 和请求告诉我新状态已加载,但选项卡显示空内容和 api 调用状态未执行

这是我的状态/路由配置:

$stateProvider
      .state('home', {
        url: '/',
        templateUrl: 'modules/core/views/home.client.view.html'
      })
      .state('home.feed', {
        abstract: true,
        url: '',
        template: '<div ui-view="list" ng-show="$state.includes(\'home.feed.list\')"/>'+
                  '<div ui-view="view" ng-show="$state.includes(\'home.feed.view\')"/>'+
                  '<div ui-view="profile" ng-show="$state.includes(\'home.feed.profile\')"/>',
        data: {
          roles: ['user', 'admin']
        },
        sticky: true,
        deepStateRedirect: true
      })
      .state('home.feed.list', {
        url: 'posts',
        views: {
          'list@home.feed': {
            templateUrl: 'modules/posts/views/list-feed.client.view.html'
          }
        },
        sticky: true
      })
      .state('home.feed.view', {
        url: 'posts/:postId',
        views: {
          'view@home.feed': {
            templateUrl: 'modules/posts/views/view-post.client.view.html'
          }
        },
        sticky: true
      })
      .state('home.create', {
        abstract: true,
        url: '',
        template: '<div ui-view="form" ng-show="$state.includes(\'home.create.form\')"/>',
        data: {
          roles: ['user', 'admin']
        },
        sticky: true,
        deepStateRedirect: true
      })
      .state('home.create.form', {
        url: 'create',
        views: {
          'form': {
            templateUrl: 'modules/posts/views/create-post.client.view.html'
          }
        },
        sticky: true
      });

“home”状态包含所有选项卡的 ui-view 以及导航栏。每个抽象状态代表一个选项卡,并包含其所有子状态的命名视图。状态的第 3 级(例如 home.feed.list)代表实际内容。

//home
<div data-ng-controller="HomeController">

  <ui-view></ui-view>

  <div class="navbar navbar-fixed-bottom">
    <tabs data="tabData" type="tabs" justified="true" template-url="modules/core/views/custom-tab-template.client.view.html"></tabs>
  </div>

</div>

//home.feed.list
<section data-ng-controller="PostsController" data-ng-init="loadPosts()">
...
</section>

//home.feed.view
<section data-ng-controller="PostsController" data-ng-init="findOne()">
...
</section>

//home.create.form
<section data-ng-controller="PostsController">
...
</section>

这些视图使用相同的控制器,但我已经尝试为每个视图添加一个单独的控制器。此外,我尝试删除 ui-router-tabs 并通过 url 调用状态,结果相同。

示例调试输出:home.feed.list -> home.create.form -> home.feed.list(抱歉没有足够的声誉来发布图片)

Current transition:  : {}:  -> home.feed.list: {}
Before transition, inactives are:   :  []
After transition,  inactives will be:  []
Transition will exit:   []
Transition will enter:  ["ENTER: home", "ENTER: home.feed", "ENTER: home.feed.list"]
SurrogateFromPath:  []
SurrogateToPath:    ["home", "home.feed", "home.feed.list"]
I am initializing PostsController
Current state: home.feed.list, inactive states:  []
Views: (__inactives.locals) / (root.locals) / (home.locals: '@' (home)) / (home.locals: '@' (home)) / (home.feed.locals: '@home' (home.feed)) / (home.feed.list.locals: 'list@home.feed' (home.feed.list))
Current transition:  home.feed.list: {}:  -> home.create.form: {}
Before transition, inactives are:   :  []
After transition,  inactives will be:  ["home.feed", "home.feed.list"]
Transition will exit:   ["(home)", "INACTIVATE: home.feed", "INACTIVATE: home.feed.list"]
Transition will enter:  ["(home)", "ENTER: home.create", "ENTER: home.create.form"]
SurrogateFromPath:  ["home", "inactivate:home.feed", "inactivate:home.feed.list"]
SurrogateToPath:    ["home", "home.create", "home.create.form"]
I am initializing PostsController
Current state: home.create.form, inactive states:  ["home.feed.list", "home.feed"]
Views: (__inactives.locals: '@home' (home.feed), 'list@home.feed' (home.feed.list)) / (root.locals) / (home.locals: '@' (home)) / (home.locals: '@' (home)) / (home.create.locals: '@home' (home.create)) / (home.create.form.locals: 'form@home.create' (home.create.form))
Current transition:  home.create.form: {}:  -> home.feed.list: {}
Before transition, inactives are:   :  ["home.feed.list", "home.feed"]
After transition,  inactives will be:  ["home.create", "home.create.form"]
Transition will exit:   ["(home)", "INACTIVATE: home.create", "INACTIVATE: home.create.form"]
Transition will enter:  ["(home)", "REACTIVATE: home.feed", "REACTIVATE: home.feed.list"]
SurrogateFromPath:  ["home", "reactivate_phase1:home.feed", "reactivate_phase1:home.feed.list", "inactivate:home.create", "inactivate:home.create.form"]
SurrogateToPath:    ["home", "reactivate_phase1:home.feed", "reactivate_phase1:home.feed.list", "reactivate_phase2:home.feed", "reactivate_phase2:home.feed.list"]
I am initializing PostsController
Current state: home.feed.list, inactive states:  ["home.create.form", "home.create"]
Views: (__inactives.locals: '@home' (home.create), 'form@home.create' (home.create.form)) / (root.locals) / (home.locals: '@' (home)) / (home.locals: '@' (home)) / (home.feed.locals: '@home' (home.feed)) / (home.feed.list.locals: 'list@home.feed' (home.feed.list))

当我使用 3 个不同的控制器时会生成相同的输出(“我正在初始化..”在每个控制器上执行)。

我发现了错误:

  1. 因为第二级状态(home.feed 和 home.create)也需要粘性,所以它们需要一个命名的父 ui-view。我忘记将 home-html 中的单个 ui-view 更改为两个命名的 ui-views。

当然,我必须调整状态定义:

.state('home.feed', {
        url: '',
        views: {
          'feed@home': {
            template: '<div ui-view="list" ng-show="$state.includes(\'home.feed.list\')"></div>'+
            '<div ui-view="view" ng-show="$state.includes(\'home.feed.view\')"></div>'+
            '<div ui-view="profile" ng-show="$state.includes(\'home.feed.profile\')"></div>'
          }
        },
        data: {
          roles: ['user', 'admin']
        },
        sticky: true,
        deepStateRedirect: {
          default: { state: "home.feed.list" }
        }
      })
      .state('home.create', {
        abstract: true,
        url: '',
        views: {
          'create@home': {
            template: '<div ui-view="form" ng-show="$state.includes(\'home.create.form\')"></div>'
          }
        },
        data: {
          roles: ['user', 'admin']
        },
        sticky: true,
        deepStateRedirect: true
      })
  1. 此问题是由于使用包含结束标记的 div 引起的。我将其更改为带有开始和结束标记的标准定义(与上面的模板定义不同)。
