Vue3學習（三）之網站首頁佈局開發

Vue網站

一、前言

上篇文章已經提到整合Ant Design Vue後，和Element Ui一樣，還是元件的使用，然後就是複製貼上改了。

二、實際案例

先搞個佈局佈局看看，也就是我們說的layout，如下圖：

不在Home中修改，因為什麼，每個頁面都有頭部和底部，寫起來較麻煩，而變化動態的部分放在Home裡面維護即可。

1、修改App.vue

先忽略路由問題，在App.vue中修改，示例程式碼如下：

<template>
  <a-layout>
    <a-layout-header class="header">
      <div class="logo" />
      <a-menu
          theme="dark"
          mode="horizontal"
          v-model:selectedKeys="selectedKeys1"
          :style="{ lineHeight: '64px' }"
      >
        <a-menu-item key="1">nav 1</a-menu-item>
        <a-menu-item key="2">nav 2</a-menu-item>
        <a-menu-item key="3">nav 3</a-menu-item>
      </a-menu>
    </a-layout-header>
    <a-layout>
      <a-layout-sider width="200" style="background: #fff">
        <a-menu
            mode="inline"
            v-model:selectedKeys="selectedKeys2"
            v-model:openKeys="openKeys"
            :style="{ height: '100%', borderRight: 0 }"
        >
          <a-sub-menu key="sub1">
            <template #title>
              <span>
                <user-outlined />
                subnav 1
              </span>
            </template>
            <a-menu-item key="1">option1</a-menu-item>
            <a-menu-item key="2">option2</a-menu-item>
            <a-menu-item key="3">option3</a-menu-item>
            <a-menu-item key="4">option4</a-menu-item>
          </a-sub-menu>
          <a-sub-menu key="sub2">
            <template #title>
              <span>
                <laptop-outlined />
                subnav 2
              </span>
            </template>
            <a-menu-item key="5">option5</a-menu-item>
            <a-menu-item key="6">option6</a-menu-item>
            <a-menu-item key="7">option7</a-menu-item>
            <a-menu-item key="8">option8</a-menu-item>
          </a-sub-menu>
          <a-sub-menu key="sub3">
            <template #title>
              <span>
                <notification-outlined />
                subnav 3
              </span>
            </template>
            <a-menu-item key="9">option9</a-menu-item>
            <a-menu-item key="10">option10</a-menu-item>
            <a-menu-item key="11">option11</a-menu-item>
            <a-menu-item key="12">option12</a-menu-item>
          </a-sub-menu>
        </a-menu>
      </a-layout-sider>
      <a-layout style="padding: 0 24px 24px">
        <a-breadcrumb style="margin: 16px 0">
          <a-breadcrumb-item>Home</a-breadcrumb-item>
          <a-breadcrumb-item>List</a-breadcrumb-item>
          <a-breadcrumb-item>App</a-breadcrumb-item>
        </a-breadcrumb>
        <a-layout-content
            :style="{ background: '#fff', padding: '24px', margin: 0, minHeight: '280px' }"
        >
          Content
        </a-layout-content>
      </a-layout>
    </a-layout>
    <a-layout-footer style="text-align: center">
      Ant Design ©2018 Created by Ant UED
    </a-layout-footer>
  </a-layout>
</template>

<style>
#components-layout-demo-top-side-2 .logo {
  float: left;
  width: 120px;
  height: 31px;
  margin: 16px 24px 16px 0;
  background: rgba(255, 255, 255, 0.3);
}

.ant-row-rtl #components-layout-demo-top-side-2 .logo {
  float: right;
  margin: 16px 0 16px 24px;
}

.site-layout-background {
  background: #fff;
}
</style>

效果如圖：

2、調整佈局

咋一看，樣式和佈局比較亂，我在調整下佈局，對程式碼進行修改如下：

<template>
  <a-layout>
    <a-layout-header class="header">
      <div class="logo" />
      <a-menu
          theme="dark"
          mode="horizontal"
          v-model:selectedKeys="selectedKeys1"
          :style="{ lineHeight: '64px' }"
      >
        <a-menu-item key="1">nav 1</a-menu-item>
        <a-menu-item key="2">nav 2</a-menu-item>
        <a-menu-item key="3">nav 3</a-menu-item>
      </a-menu>
    </a-layout-header>
    <a-layout>
      <a-layout-sider width="200" style="background: #fff">
        <a-menu
            mode="inline"
            v-model:selectedKeys="selectedKeys2"
            v-model:openKeys="openKeys"
            :style="{ height: '100%', borderRight: 0 }"
        >
          <a-sub-menu key="sub1">
            <template #title>
                <span>
                  <user-outlined />
                  subnav 1
                </span>
            </template>
            <a-menu-item key="1">option1</a-menu-item>
            <a-menu-item key="2">option2</a-menu-item>
            <a-menu-item key="3">option3</a-menu-item>
            <a-menu-item key="4">option4</a-menu-item>
          </a-sub-menu>
          <a-sub-menu key="sub2">
            <template #title>
                <span>
                  <laptop-outlined />
                  subnav 2
                </span>
            </template>
            <a-menu-item key="5">option5</a-menu-item>
            <a-menu-item key="6">option6</a-menu-item>
            <a-menu-item key="7">option7</a-menu-item>
            <a-menu-item key="8">option8</a-menu-item>
          </a-sub-menu>
          <a-sub-menu key="sub3">
            <template #title>
                <span>
                  <notification-outlined />
                  subnav 3
                </span>
            </template>
            <a-menu-item key="9">option9</a-menu-item>
            <a-menu-item key="10">option10</a-menu-item>
            <a-menu-item key="11">option11</a-menu-item>
            <a-menu-item key="12">option12</a-menu-item>
          </a-sub-menu>
        </a-menu>
      </a-layout-sider>
      <a-layout-content
          :style="{ background: '#fff', padding: '24px', margin: 0, minHeight: '280px' }"
      >
        Content
      </a-layout-content>
    </a-layout>
    <a-layout-footer style="text-align: center">
      軟體測試君 ©2021 Created by 六哥
    </a-layout-footer>
  </a-layout>
</template>

<style>
#components-layout-demo-top-side-2 .logo {
  float: left;
  width: 120px;
  height: 31px;
  margin: 16px 24px 16px 0;
  background: rgba(255, 255, 255, 0.3);
}

.ant-row-rtl #components-layout-demo-top-side-2 .logo {
  float: right;
  margin: 16px 0 16px 24px;
}

.site-layout-background {
  background: #fff;
}
</style>

修改完效果如下：

3、修改路由實現跳轉

前面已經說到，只需修改動態部分建立路由，實現跳轉訪問動態部分即可，這裡的頁頭和頁尾不會改變及二級選單，只修改content部分即可。

修改Home.vue，示例程式碼如下：

<template>
  <a-layout>
    <a-layout-sider width="200" style="background: #fff">
      <a-menu
          mode="inline"
          v-model:selectedKeys="selectedKeys2"
          v-model:openKeys="openKeys"
          :style="{ height: '100%', borderRight: 0 }"
      >
        <a-sub-menu key="sub1">
          <template #title>
                <span>
                  <user-outlined />
                  subnav 1
                </span>
          </template>
          <a-menu-item key="1">option1</a-menu-item>
          <a-menu-item key="2">option2</a-menu-item>
          <a-menu-item key="3">option3</a-menu-item>
          <a-menu-item key="4">option4</a-menu-item>
        </a-sub-menu>
        <a-sub-menu key="sub2">
          <template #title>
                <span>
                  <laptop-outlined />
                  subnav 2
                </span>
          </template>
          <a-menu-item key="5">option5</a-menu-item>
          <a-menu-item key="6">option6</a-menu-item>
          <a-menu-item key="7">option7</a-menu-item>
          <a-menu-item key="8">option8</a-menu-item>
        </a-sub-menu>
        <a-sub-menu key="sub3">
          <template #title>
                <span>
                  <notification-outlined />
                  subnav 3
                </span>
          </template>
          <a-menu-item key="9">option9</a-menu-item>
          <a-menu-item key="10">option10</a-menu-item>
          <a-menu-item key="11">option11</a-menu-item>
          <a-menu-item key="12">option12</a-menu-item>
        </a-sub-menu>
      </a-menu>
    </a-layout-sider>
    <a-layout-content
        :style="{ background: '#fff', padding: '24px', margin: 0, minHeight: '280px' }"
    >
      Content
    </a-layout-content>
  </a-layout>
</template>

<script lang="ts">
import { defineComponent } from 'vue';
import HelloWorld from '@/components/HelloWorld.vue'; // @ is an alias to /src

export default defineComponent({
  name: 'Home',
  components: {
    HelloWorld,
  },
});
</script>

修改App.vue實現路由跳轉：示例程式碼如下：

<template>
  <a-layout>
    <a-layout-header class="header">
      <div class="logo" />
      <a-menu
          theme="dark"
          mode="horizontal"
          v-model:selectedKeys="selectedKeys1"
          :style="{ lineHeight: '64px' }"
      >
        <a-menu-item key="1">nav 1</a-menu-item>
        <a-menu-item key="2">nav 2</a-menu-item>
        <a-menu-item key="3">nav 3</a-menu-item>
      </a-menu>
    </a-layout-header>
    <router-view/>
    <a-layout-footer style="text-align: center">
      軟體測試君 ©2021 Created by 六哥
    </a-layout-footer>
  </a-layout>
</template>

<style>
#components-layout-demo-top-side-2 .logo {
  float: left;
  width: 120px;
  height: 31px;
  margin: 16px 24px 16px 0;
  background: rgba(255, 255, 255, 0.3);
}

.ant-row-rtl #components-layout-demo-top-side-2 .logo {
  float: right;
  margin: 16px 0 16px 24px;
}

.site-layout-background {
  background: #fff;
}
</style>

熱部署編譯後報錯如下圖：

從報錯的得知，校驗規則報錯，很簡單一個是刪除未註冊元件HelloWorld，第二種方法，就是修改校驗檔案規則，在eslintrc.js中新增如下內容：

  rules: {
    'no-console': process.env.NODE_ENV === 'production' ? 'warn' : 'off',
    'no-debugger': process.env.NODE_ENV === 'production' ? 'warn' : 'off',
    'vue/no-unused-components':'off'
  }

這是自動編譯還是會報錯，如下圖：
