VUE读取execl文件
VUE读取execl文件 实现页面预览数据
·
需要读取的文件格式
1.安装插件
npm install xlsx2.引入
<script>
import * as XLSX from 'xlsx'
</script>3.上传
<input type="file" @change="handleFileUpload" name="" ref="fjset">上传事件读取
handleFileUpload(event) {
const files = event.target.files || event.dataTransfer.files;
this.files = [];
for (let i = 0; i < files.length; i++) {
const imgType = files[i].type === "application/vnd.ms-excel";
if (!imgType) {
this.$message.error("请选择excel文件");
return false;
}
const isLt10M = files[i].size / 1024 / 1024 < 10;
if (!isLt10M) {
this.$message.error("文件大小不能大于10M!");
return false;
}
}
const file = event.target.files[0];
const than=this
than.tableData=[]//读取所有的数据数组
than.tableDatadq=[]//分页后的数组
than.sousuo.page=1;
than.sousuo.pageSize=5
// 用readAsBinaryString或readAsArrayBuffer读取文件内容（根据xlsx版本可能需要不同方式）
const reader = new FileReader();
reader.onload = (e) => {
const data = e.target.result;
console.log(XLSX)
let workbook;
if (typeof data === 'string') { // 对于旧版xlsx，可能直接是二进制字符串
workbook = XLSX.read(data, {type: 'binary'});
} else { // 对于新版xlsx，通常为ArrayBuffer
workbook = XLSX.read(new Uint8Array(data), {type: 'array'});
}
// 获取第一个工作表
const worksheet = workbook.Sheets[workbook.SheetNames[0]];
// 模板应有的列名和顺序校验模板
const requiredColumnsOrder = ['姓名 *','身份证号 *','银行卡账号 *','考勤天数 *', '应发工资 *', '扣发工资 *',"班组名称","备注"];
const headerRow = XLSX.utils.sheet_to_json(worksheet, { header: 1 })[0]; // 获取第一行作为标题行
// 检查列名是否存在并且顺序正确
if (requiredColumnsOrder.some((col, index) => headerRow[index] !== col)) {
this.$message.error('模板文件的结构不正确，请检查列名或列顺序！');
return;
}
// 将工作表转换为JSON对象数组
let excelData = XLSX.utils.sheet_to_json(worksheet);
// 现在excelData是一个包含表格数据的数组，你可以在此处进一步处理数据，并绑定到Vue实例的数据属性上
const fieldMap = {
'姓名 *': 'aac003',
'应发工资 *': 'bac313',
'扣发工资 *': 'bac314',
'班组名称': 'bac502',
'考勤天数 *': 'bac303',
'身份证号 *': 'aac002',
'银行卡账号 *': 'aae010',
'备注':'aae013'
};
excelData = excelData.map(row => {
return Object.keys(row).reduce((newRow, key) => {
if (fieldMap[key]) {
newRow[fieldMap[key]] = row[key];
} else {
newRow[key] = row[key]; // 如果没有对应英文名称，保留原字段名
}
return newRow;
}, {});
});
than.tableData = excelData;
console.log(than.tableData)
//分页方法
than.getTabelData()
};
this.$refs['fjset'].value = '';
reader.readAsArrayBuffer(file); // 读取为ArrayBuffer，适用于大多数情况
},4.页面显示 可以对导入的数据进行修改和删除 分页
