handleChange(file: any, fileList: any) {
console.log("更新------", file, "bbbbbbbbb", fileList);
this.fileList = [fileList[fileList.length - 1]]; //只能上传一个`Excel`,重复上传会覆盖之前的
this.file = file.raw;
const reader = new FileReader();
reader.readAsArrayBuffer(this.file);
reader.onload = () => {
const buffer: any = reader.result;
const bytes = new Uint8Array(buffer);
const length = bytes.byteLength;
let binary = "";
for (let i = 0; i < length; i++) {
binary += String.fromCharCode(bytes[i]);
}
const wb = XLSX.read(binary, { type: "binary", cellDates: true }); //cellDates,设置为true,将天数的时间戳转为时间格式
const outdata = XLSX.utils.sheet_to_json(wb.Sheets[wb.SheetNames[0]]);
console.log("outdata", outdata);
};
}
}
