Bootstrap导航栏在路线更改时保持扩展 [英] Bootstrap navbar stays expanded on route change

问题描述

我有一个使用铁路由器的Meteor项目.

I've got a Meteor project which uses iron-router.

在我的项目中，我有一个引导导航栏，不幸的是，每当导航栏展开时(由于屏幕显示的是最小宽度)，我导航到某个路线时，导航栏就会在我转到新路线时保持展开状态.

In my project I have a bootstrap navbar and unfortunately whenever I navigate to a route while the navbar is expanded (due to the screen being min width), the navbar remains expanded when I go to a new route.

是否有一种方法可以将导航栏设置为在更改路由时像通常的页面刷新一样再次折叠?

Is there a way to set the navbar to collapse again upon changing routes like it would with a usual page refresh?

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">
                        <li>
                            <a href="/headsortails">Heads or Tails</a>
                        </li>
                    </ul>
                </li>
                <li class="dropdown">
                    <a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-haspopup="true" aria-expanded="false"><span class="glyphicon glyphicon-stats"></span>&nbsp;&nbsp;&nbsp;&nbsp;Leaderboards <span class="caret"></span></a>
                    <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 class="dropdown">
                            <a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-haspopup="true" aria-expanded="false"><span class="glyphicon glyphicon-cog"></span>&nbsp;&nbsp;&nbsp;&nbsp;Maintenance <span class="caret"></span></a>
                            <ul class="dropdown-menu">
                                <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='login'}}"><span class="glyphicon glyphicon-log-in"></span>&nbsp;&nbsp;&nbsp;&nbsp;Log in</a></li>
                    <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');

推荐答案

一个优雅但实用的解决方案是检查导航栏是否已扩展，然后单击它-根据Barry Doyle的解决方案

An inelegant but practical solution is to check if the navbar is expanded THEN click on it - as per Barry Doyle's solution

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