Vue3 (III) Website Homepage Layout Development

Vue3 (III) Website Homepage Layout Development

1. Introduction

In the previous article, Vue3 integrates Ant Design Vue. It has been mentioned that after integrating Ant Design Vue, like Element Ui, components are still used, and then they are copied and pasted.

2. Actual Cases

Let's first make a layout, which is what we call layout , as shown below:

Don’t modify it in Home . Why? Every page has a header and a footer, which are more troublesome to write. The dynamically changing parts can be maintained in Home .

1. Modify App.vue

Ignore the routing problem for now and modify it in App.vue . The sample code is as follows:

html:

<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>

The effect is as shown below:

2. Adjust the layout

At first glance, the style and layout are messy. I adjusted the layout and modified the code as follows:

html:

<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">
      Software Tester©2021 Created by Liuge</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>

The modified effect is as follows:

3. Modify the route to achieve jump

As mentioned before, you only need to modify the dynamic part to establish the route and realize the jump access to the dynamic part. The header and footer here will not change, as well as the secondary menu. Only content part needs to be modified.

Modify Home.vue. The sample code is as follows:

js:

<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>

Modify App.vue to implement route jump: The sample code is as follows:

html:

<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">
      Software Tester©2021 Created by Liuge</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>

The error after hot deployment compilation is as follows:

From the error report, we know that the verification rule reports an error. A simple way is to delete the unregistered component HelloWorld . The second method is to modify the verification file rules and add the following content in eslintrc.js :

js:

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

Is this automatic compilation still going to give an error, as shown below:

There is nothing to be afraid of when an error is reported. Don't panic. Restart the service as follows:

This time I accessed the page address directly, and the effect was as follows:

Then visit the about page, as shown below:
