Bootstrap 导航栏在路线更改时保持扩展

Question

我有一个使用 Iron-router 的 Meteor 项目。

在我的项目中，我有一个引导导航栏，不幸的是，每当我在导航栏展开时导航到一条路线（由于屏幕是最小宽度），当我转到一条新路线时，导航栏仍然处于展开状态。

有没有办法将导航栏设置为在更改路线时再次折叠，就像通常的页面刷新一样？

导航栏模板：

<template name="navigation">
  <nav class="navbar navbar-default">
    <div class="container-fluid">
        <div class="navbar-header">
            <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#navbar-collapse" aria-expanded="false">
                <span class="sr-only">Toggle navigation</span>
                <span class="icon-bar"></span>
                <span class="icon-bar"></span>
                <span class="icon-bar"></span>
            </button>
            <a class="navbar-brand" href="{{pathFor route='home'}}"><span class="glyphicon glyphicon-home"></span>&nbsp;&nbsp;&nbsp;&nbsp;RNG Leaderboard</a>
        </div>

        <div class="navbar-collapse collapse" id="navbar-collapse" aria-expanded="false" style="height: 1px;">
            <ul class="nav navbar-nav">
                <li class="dropdown">
                    <a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-haspopup="true" aria-expanded="false"><span class="glyphicon glyphicon-phone"></span>&nbsp;&nbsp;&nbsp;&nbsp;Games <span class="caret"></span></a>
                    <ul class="dropdown-menu">

                            <a href="/headsortails">Heads or Tails</a>
                        </li>
                    </ul>
                </li>
                <li class="dropdown">

                    <ul class="dropdown-menu">
                        <li>
                            <a href="/headsortailsleaderboard">Heads or Tails</a>
                        </li>
                    </ul>
                </li>
            </ul>
            <ul class="nav navbar-nav navbar-right">
                {{#if currentUser}}
                    {{#if isInRole 'admin'}}

                                <li>
                                    <a href="/manageusers"><span class="glyphicon glyphicon-user"></span>&nbsp;&nbsp;&nbsp;&nbsp;Manage Users</a>
                                </li>
                            </ul>
                        </li>
                    {{/if}}
                    <li><a href="/@{{currentUser.username}}"><span class="glyphicon glyphicon-user"></span>&nbsp;&nbsp;&nbsp;&nbsp;{{currentUser.profile.firstName}}&nbsp;{{currentUser.profile.lastName}}</a></li>
                    <li><a id="logout" href="{{pathFor route='login'}}"><span class="glyphicon glyphicon-log-out"></span>&nbsp;&nbsp;&nbsp;&nbsp;Log out</a></li>
                {{else}}

                    <li><a href="{{pathFor route='signup'}}"><span class="glyphicon glyphicon-pencil"></span>&nbsp;&nbsp;&nbsp;&nbsp;Sign up</a></li>
                {{/if}}
            </ul>
        </div>
    </div>
  </nav>
</template>

路由器代码：

Router.configure({
  layoutTemplate: 'layout', // Defines the layout template
  loadingTemplate: 'loading', // Defines the loading template
  onAfterAction: function(){
    $('.nav-collapse').collapse('hide');
  }
});

Router.plugin('dataNotFound', {
  notFoundTemplate: 'dataNotFound'
});

Router.route('/', {
  name: 'home',
  template: 'home'
});

Router.route('/signup');
Router.route('/login');
Router.route('/recoverpassword');
Router.route('/resetpassword');

Router.route('/manageusers', {
  name: 'manageusers',
  controller: 'ManageUsersController',
});

ManageUsersController = RouteController.extend({
  template: 'manageusers',
  before: function() {
    if (!Roles.userIsInRole(Meteor.userId(), 'admin')) {
      this.redirect('home');
    } else {
      this.render('manageusers');
    }
  }
});

var usernameRoute = '/@:username';
Router.route(usernameRoute, {
  name: 'profile',
  controller: 'ProfileController'
});

ProfileController = RouteController.extend({
  template: 'profile',
  waitOn: function() {
    return Meteor.subscribe('userProfile', this.params.username);
  },
  data: function() {
    var username = Router.current().params.username;
    return Meteor.users.findOne({
      username: username
    });
  }
});

Router.route('/headsortails');
Router.route('/headsortailsleaderboard');

Answer 1

一个不雅但实用的解决方案是检查导航栏是否已展开然后单击它 - 根据 Barry Doyle 的解决方案

  closeNavBar: function() {
    var isExpanded = $('.navbar-toggle').attr('aria-expanded') === true;
    if(isExpanded) {
      $('.navbar-toggle').click();
    }
    this.next();
  },

Answer 2

根据 Michel 的回答和一些挖掘，我在我的 router.js 文件中提出了以下解决方案：

Router.configure({
  onAfterAction: function(){
    $('.navbar-toggle').click();
  }
});

Answer 3

Neigher 提供的两种解决方案都有效。

必须是这样的。 attr() 返回字符串 'true' 或 'false' 不是布尔值，这就是为什么使用 === 'true'。

Router.configure({
    ...
    onAfterAction() {
        const navbarToggle = $('.navbar-toggle');
        if (navbarToggle.attr('aria-expanded') === 'true') {
            navbarToggle.click();
        }
    }
});
