Vue.js 案例——商品管理

一.需要做出的效果图：

二.实现的步骤

首先，先建一个项目，命名Table，在Table项目中的components里新建一个MyTable.vue文件。

第二步，在原有的 HelloWorld.vue中写入代码。

HelloWorld.vue代码如下：

<script setup>
import { ref } from 'vue'
 
defineProps({
  msg: String,
})
 
const count = ref(0)
</script>
 
<template>
  <h1>{{ msg }}</h1>
 
  <div class="card">
    <button type="button" @click="count++">count is {{ count }}</button>
    <p>
      Edit
      <code>components/HelloWorld.vue</code> to test HMR
    </p>
  </div>
 
  <p>
    Check out
    <a href="https://vuejs.org/guide/quick-start.html#local" target="_blank"
      >create-vue</a
    >, the official Vue + Vite starter
  </p>
  <p>
    Install
    <a href="https://github.com/johnsoncodehk/volar" target="_blank">Volar</a>
    in your IDE for a better DX

</template>
 
<style scoped>
.read-the-docs {
  color: #888;
}
</style>复制

MyTable.vue代码如下：

<template>
  <table class="table table-striped table-bordered">
    <!-- 表格标题区域 -->
    <thead>
      <tr>
        <slot name="header"></slot>
      </tr>
    </thead>
    <!-- 表格主体区域 -->
    <tbody>
      <tr v-for="(item, index) in goodsList" :key="item.id">
        <slot name="body" :row="item" :index="index"></slot>
      </tr>
    </tbody>
  </table>
</template>
 
<script setup>
const props = defineProps({
  goodsList: {
    type: Array,
    required: true,
    default: []
  }
})
</script>复制

在App.vue中写入代码：

<template>
  <h4>商品管理</h4>
  <MyTable :goodsList="goodsList">
    <template v-slot:header>
      <th scope="col">#</th>
      <th scope="col">商品名称</th>
      <th scope="col">价格</th>
      <th scope="col">标签</th>
      <th scope="col">操作</th>
    </template>
    <template #body="{ row, index }">
      <td>{{ index + 1 }}</td>
      <td>{{ row.goods_name }}</td>
      <td>￥{{ row.goods_price }}</td>
      <td>
        <input type="text" v-if="row.inputVisible" class="form-control form-control-sm ipt-tag" v-focus
          v-model="row.inputValue" 
          @keyup.esc="row.inputValue = ''"
          @blur="onInputConfig(row)"
          @keyup.enter="onInputConfig(row)"
        />
        <button class="btn btn-outline-primary rounded-pill" v-else @click="row.inputVisible = true">+Tag</button>
        <span class="btn btn-outline-dark" v-for="item in row.tags" :key="item">
          {{ item }}
        </span>
      </td>
      <td>
        <button type="button" class="btn btn-outline-danger btn-sm" @click="onRemove(row.id)">删除</button>
      </td>
    </template>
  </MyTable>
</template>
 
<script setup>
import MyTable from './components/MyTable.vue'
 
import { ref } from 'vue'
 
const goodsList = ref([
  {
    id: 1,
    goods_name: '夏季专柜同款女鞋',
    goods_price: 298,
    tags: ['舒适', '透气'],
    inputVisible: false,
    inputValue: ''
  },
  {
    id: 2,
    goods_name: '冬季保暖女士休闲雪地靴 舒适加绒防水短靴 防滑棉鞋',
    goods_price: 89,
    tags: ['保暖', '防滑'],
    inputVisible: false,
    inputValue: ''
  },
  {
    id: 3,
    goods_name: '秋冬新款女士毛衣 套头宽松针织衫 简约上衣',
    goods_price: 199,
    tags: ['秋冬', '毛衣'],
    inputVisible: false,
    inputValue: ''
  },
  {
    id: 4,
    goods_name: '2023春秋装新款大码女装 衬衫 上衣',
    goods_price: 19,
    tags: ['雪纺衫', '打底'],
    inputVisible: false,
    inputValue: ''
  },
  {
    id: 5,
    goods_name: '长款长袖圆领女士毛衣 2022秋装新款假两件连衣裙',
    goods_price: 178,
    tags: ['圆领', '连衣裙'],
    inputVisible: false,
    inputValue: ''
  }
])
 
const onRemove = id => {
  goodsList.value = goodsList.value.filter(item => item.id != id)
}
 
const vFocus = el => { el.focus() }
 
const onInputConfig = row => {
  const val = row.inputValue
  row.inputValue = ''
  row.inputVisible = false
  if (!val || row.tags.indexOf(val) !== -1) {
    return
  }
	row.tags.push(val)
}
</script>
 
<style scoped>
th {
  text-align: center;
}
td {
  line-height: 30px;
}
.ipt-tag {
  width: 80px;
  display: inline;
}
input, span, button {
  margin-right: 10px;
}
</style>复制

最后，修改main.js的代码：

import { createApp } from 'vue'
import './bootstrap.css'
import App from './App.vue'
 
createApp(App).mount('#app')复制

三.运行结果

按ctrl+s保存，运行其结果：

点击+Tag可以添加不同的标签，例如：

点击删除也可以删除该行，删除如上第一行，如下所示：
