Question

在bootstrap官方文档中，我看到了很酷的导航丸。就是这样。

<div class="nav flex-column nav-pills" id="v-pills-tab" role="tablist" aria-orientation="vertical">
  <a class="nav-link active" id="v-pills-home-tab" data-toggle="pill" href="#v-pills-home" role="tab" aria-controls="v-pills-home" aria-selected="true">Home</a>
  <a class="nav-link" id="v-pills-profile-tab" data-toggle="pill" href="#v-pills-profile" role="tab" aria-controls="v-pills-profile" aria-selected="false">Profile</a>
  <a class="nav-link" id="v-pills-messages-tab" data-toggle="pill" href="#v-pills-messages" role="tab" aria-controls="v-pills-messages" aria-selected="false">Messages</a>
  <a class="nav-link" id="v-pills-settings-tab" data-toggle="pill" href="#v-pills-settings" role="tab" aria-controls="v-pills-settings" aria-selected="false">Settings</a>
</div>
<div class="tab-content" id="v-pills-tabContent">
  <div class="tab-pane fade show active" id="v-pills-home" role="tabpanel" aria-labelledby="v-pills-home-tab">...</div>
  <div class="tab-pane fade" id="v-pills-profile" role="tabpanel" aria-labelledby="v-pills-profile-tab">...</div>
  <div class="tab-pane fade" id="v-pills-messages" role="tabpanel" aria-labelledby="v-pills-messages-tab">...</div>
  <div class="tab-pane fade" id="v-pills-settings" role="tabpanel" aria-labelledby="v-pills-settings-tab">...</div>
</div>

这是我目前用于导航的代码。

<ul class="nav flex-column">
          <li class="nav-item">
            <router-link to="/studentDashboard">Dashboard</router-link>
          </li>

          <li class="nav-item">
            <router-link to="/buyPapers">Buy papers</router-link>
          </li>

          <li class="nav-item" >
            <router-link to="/myPapers">My papers</router-link>
          </li>

  </ul>

在此代码中，我应该更改哪些药片？

Answer 1

<router-link> by defult is rendered as an achor tag `<a>`.

Bootstap 4 nav-pills具有<a>标记，其中包含类nav-link。如下：

<ul class="nav nav-pills">
  <li class="nav-item">
    <a class="nav-link active" href="#">Active</a>
  </li>
  <li class="nav-item">
    <a class="nav-link" href="#">Link</a>
  </li>
  </li>
</ul>

只需将该课程添加到<router-link>

即可

<li class="nav-item">
  <router-link class="nav-link" active-class="active" to="/studentDashboard">Dashboard</router-link>
</li>

要将active类添加到代表当前活动路线的nav-pill中，请在每个`

上添加active-class道具

Answer 2

使用活动标签和标签内容的Vue路由器控件显示而不是Bootstrap。每个tab-pane都应该有active类，因为路由器用于控制路由器视图的显示......

const home = { template: '<div class="tab-pane active">Home...</div>' }
const profile = { template:'<div class="tab-pane active">Profile.. </div>' }
const more  = { template:'<div class="tab-pane active">More..</div>' }

然后，使用一种方法在每个导航丸上有条件地设置active类......

methods: {
      activeClass: function (...names) {
        for (let name of names) {
            if (name == this.$route.name)
                return 'active';
      }
    }    
}

HTML

<ul class="nav nav-pills">
    <li class="nav-item">
         <router-link to="/home" class="nav-link" :class="activeClass('home')">Home</router-link>
    </li>
    <li class="nav-item">
         <router-link to="/profile" class="nav-link" :class="activeClass('profile')">Profile</router-link>
    </li>
    <li class="nav-item">
         <router-link to="/more" class="nav-link" :class="activeClass('more')">More</router-link>
    </li>
</ul>
<div class="tab-content">
      <router-view></router-view>
</div>
