导出功能封装

//下载文件 const download = (resdata, filename) => { //. 创建Blob对象（解决中文乱码） let blob = new Blob([resdata], { type: 'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet' }); let exportfilename = `${filename}.xlsx`; // 将blob对象转为一个URL var blobURL = window.URL.createObjectURL(blob); // 创建一个a标签 触发下载 var tempLink = document.createElement('a'); tempLink.style.display = 'none'; tempLink.href = blobURL; tempLink.setAttribute('download', exportfilename); if (typeof tempLink.download === 'undefined') { tempLink.setAttribute('target', '_blank'); } // 将a标签添加到body当中 document.body.appendChild(tempLink); tempLink.click(); document.body.removeChild(tempLink); window.URL.revokeObjectURL(blobURL); ElMessage({ message: '导出成功', type: 'success' }); }; //使用 download(res.data, title.value);
