// // 实例化一个Blob对象，其构造函数的第一个参数是包含文件内容的数组，第二个参数是包含文件类型属性的对象
let blob = new Blob([txt], {
type: "text/plain;charset=utf-8",
}); //application/octet-stream
//也可以用js创建一个a标签
let a = document.createElement('a');
// 利用URL.createObjectURL()方法为a元素生成blob URL
a.href = URL.createObjectURL(blob);
// 设置文件名
a.download = title + ".xls"; //xlsx
a.click();
