js实现导出/下载excel文件
// response 为导出接口返回数据,如上图
const exportExcel = (response, fileName:string) =>{
const blob = new Blob([response.data], {
type: response.headers['content-type'] //使用获取的excel格式
});
const downloadElement = document.createElement('a')
const url = window.URL.createObjectURL(blob)
downloadElement.href = url
let name = fileName || 'EXCEL导出'
downloadElement.download = `${name}.xlsx`; //下载后文件名
document.body.appendChild(downloadElement);
downloadElement.click(); //点击下载
document.body.removeChild(downloadElement); //下载完成移除元素
window.URL.revokeObjectURL(url); //释放掉blob对象
})
