无线婴儿监视器方案（附SI24R1选型）

1.安装插件(版本0.18.5)

npm i xlsx

2.封装插件

<template>
  <div class="container">
    <slot></slot>
  </div>
</template>

<script>
import * as XLSX from 'xlsx'
export default {
  name: 'ReadExcel',
  props: {
    filePath: {
      type: String,
      default: ''
    }
  },
  mounted() {
    this.readExcel()
  },
  methods: {
    readExcel() {
      // 假设你的xlsx文件位于public目录下，并命名为'example.xlsx'
      // console.log('filePath', this.filePath)
      // 使用fetch获取public下的文件
      fetch(this.filePath)
        .then(res => res.arrayBuffer())
        .then(data => {
          // 读取xlsx文件
          const workbook = XLSX.read(data, { type: 'buffer' })
          // 获取第一个工作表
          const firstSheetName = workbook.SheetNames[0]
          const worksheet = workbook.Sheets[firstSheetName]
          // 将工作表转换为JSON
          const tableData = XLSX.utils.sheet_to_json(worksheet)
          this.$emit('getData', tableData)
        })
    }
  }
}
</script>

3.页面使用(filePath文件路径为public下的user.xlsx)

<template>
  <div class="app-container">
    <ReadExcel filePath="/user.xlsx" @getData="getData">
      <el-table :data="tableData" border style="width: 100%">
        <el-table-column align="center" prop="用户编号" label="用户编号" />
        <el-table-column align="center" prop="用户名称" label="用户名称" />
        <el-table-column align="center" prop="用户昵称" label="用户昵称" />
        <el-table-column align="center" prop="部门" label="部门" />
        <el-table-column align="center" prop="手机号码" label="手机号码" />
      </el-table>
      <div class="pagination" style="display: flex; justify-content: flex-end; margin-top: 20px">
        <el-pagination @size-change="handleSizeChange" @current-change="handleCurrentChange" :page-sizes="[5, 10, 15, 20]" :page-size="listQuery.pageSize" layout="total, sizes, prev, pager, next, jumper" :total="tableData.length" />
      </div>
    </ReadExcel>
  </div>
</template>

<script>
import ReadExcel from '@/components/ReadExcel'
export default {
  name: 'User',
  components: {
    ReadExcel
  },
  data() {
    return {
      listQuery: {
        pageNum: 1,
        pageSize: 5
      },
      data: []
    }
  },
  computed: {
    tableData() {
      return this.data.slice((this.listQuery.pageNum - 1) * this.listQuery.pageSize, this.listQuery.pageNum * this.listQuery.pageSize)
    }
  },
  methods: {
    getData(val) {
      this.data = val
    },
    handleSizeChange(val) {
      this.listQuery.pageSize = val
    },
    handleCurrentChange(val) {
      this.listQuery.pageNum = val
    }
  }
}
</script>
