这一部分的网页结构相对简单，主要是css的内容和router-link的跳转。

效果如下。

主要的CSS效果

所有的tab通过li来排列。【float: left;】使所有tab横向排列。

.tab {
    float: left;
    height: 60px;
    line-height: 60px;
    text-align: center;
    padding-left: 20px;
    padding-right: 20px;
}

移动到tab上，会有上横线出现。

.tab:hover {
    border-top: #486E53 solid 3px;
}

点击选中后字体会加粗。

.tab_all>a>li:hover {
    color: #486E53;
}

页面跳转

通过router-link进行页面跳转。

<router-link to="/VisualInterface" active-class="_active" class="tab"
          >图谱展示</router-link>
<router-view></router-view>

主要代码

App.vue

<template>
  <div>
    <router-link to="/"></router-link>
    <!-- 顶部导航栏 -->
    <div id="header">
      <!-- Logo -->
      <div class="logo">
        <img src="./assets/logo.png" alt="logo" />
        <h1>IME</h1>
      </div>

      <!-- Tab -->
      <div class="tab_all">
        <router-link
          to="/DataManagement"
          active-class="_active"
          class="tab"
          style="margin-left: 20px"
          >数据管理</router-link
        >
        <router-link to="/DataProcessing" active-class="_active" class="tab"
          >数据处理</router-link
        >
        <router-link to="/Crawl" active-class="_active" class="tab"
          >数据爬虫</router-link
        >
        <router-link to="/Query" active-class="_active" class="tab"
          >知识问答</router-link
        >
        <router-link to="/News" active-class="_active" class="tab"
          >新闻热点</router-link
        >
        <router-link to="/Search" active-class="_active" class="tab"
          >词条检索</router-link
        >
        <router-link to="/VisualInterface" active-class="_active" class="tab"
          >图谱展示</router-link
        >
      </div>
    </div>
    <router-view></router-view>
  </div>
