关于javascript:前端导出excel代码

// res为后端传递的数据const blob = new Blob([res], {          type: "application/ms-excel",        });        const elink = document.createElement("a");        elink.download = "文件名.xls";        elink.style.display = "none";        elink.href = URL.createObjectURL(blob);        document.body.appendChild(elink);        elink.click();        URL.revokeObjectURL(elink.href); // 开释URL对象        document.body.removeChild(elink);

发送申请时须要设置responseType: 'blob', 不然关上的excel会有乱码
