工具类文件

// fileUtils.tsimport { ref } from 'vue';
import * as xlsx from 'xlsx';interface RowData {[key: string]: any;
}export const tableData = ref<RowData[]>([]);export async function handleFileSelect(url: string): Promise<void> {try {const response = await fetch(url);const blob = await response.blob();const reader = new FileReader();reader.onload = (e: ProgressEvent<FileReader>) => {if (e.target && e.target.result) {const data = new Uint8Array(e.target.result as ArrayBuffer);const workbook = xlsx.read(data, { type: 'array' });const worksheet = workbook.Sheets[workbook.SheetNames[0]];const jsonData = xlsx.utils.sheet_to_json(worksheet, { header: 1 }) as any[][];// 提取标题并保持其顺序const headers = jsonData[0];console.log('Extracted Headers:', headers);// 处理行（从索引1开始跳过标题）jsonData.slice(1).forEach((row) => {const rowData: RowData = {};headers.forEach((header, index) => {rowData[header] = row[index];});tableData.value.push(rowData);});console.log('Processed Table Data:', tableData.value);}};reader.readAsArrayBuffer(blob);} catch (error) {console.error('获取或读取文件时出错:', error);}
}
