Vue と Excel を使用してテーブル データを関連付けてフィルタリングする方法

npm install vue

npm install exceljs

npm install xlsx

<template>
  <div>
    <input type="file" @change="importExcel" accept=".xlsx,.xls" />
    <button @click="filterData">筛选</button>
  </div>
</template>

<script>
import { writeFile } from 'xlsx';

export default {
  methods: {
    importExcel(event) {
      const files = event.target.files;
      const reader = new FileReader();

      reader.onload = (e) => {
        const data = new Uint8Array(e.target.result);
        const workbook = XLSX.read(data, { type: 'array' });
        const worksheet = workbook.Sheets[workbook.SheetNames[0]];
        const jsonData = XLSX.utils.sheet_to_json(worksheet, { header: 1 });

        // 存储Excel数据
        this.excelData = jsonData;
      };

      reader.readAsArrayBuffer(files[0]);
    },
    filterData() {
      // 根据筛选条件过滤数据
      // ...
    },
  },
};
</script>

    <button @click="filterData">筛选</button>
    <input v-model="filterValue" placeholder="请输入筛选条件" />
    <button @click="applyFilter">确认</button>
