需要引入
1、安装插件
npm i xlsx
2、引入
import XLSX from "xlsx";
data中定义
importFile: importEquipment,//接口 accessToken: {}, uploadfile: { name: '' }, importColumns: [], importTableData: [],
js代码
//导入数据 beforeUploadImport(file) { this.uploadfile = file const fileExt = file.name .split('.') .pop() .toLocaleLowerCase() if (fileExt == 'xlsx' || fileExt == 'xls') { this.readFile(file) this.file = file } else { this.$Notice.warning({ title: '文件类型错误', desc: '所选文件‘ ' + file.name + ' '不是EXCEL文件,请选择后缀为.xlsx或者.xls的EXCEL文件。' }) } return false }, // 读取文件 readFile(file) { this.reading = true const reader = new FileReader() reader.readAsArrayBuffer(file) reader.onerror = (e) => { this.reading = false this.$Message.error('文件读取出错') } reader.onload = (e) => { console.log(e.target.result) const data = e.target.result const { header, results } = excel.read(data, 'array') const tableTitle = header.map((item) => { return { title: item, key: item, minWidth: 130, align: 'center' } }) this.importTableData = results this.importColumns = tableTitle this.reading = false this.$Message.success('读取数据成功') } }, uploadSucess(response) { if (response.code == 200) { this.$Message.success('导入成功') this.importModalVisible = false this.clearImportData() this.getDataList() } else { this.$Message.error(response.message) } this.uploadfile = {} }, clearImportData() { this.importTableData = [] this.importColumns = [] this.uploadfile = {} this.$refs.upload.clearFiles(); },
