javascript - FileSaver.js 和 Blob.js - 更改目录

Question

我正在使用 fileSaver.js 和 Blob.js 来保存这样的文件:

var blob = new Blob(["Hello, world!"], {type: "text/plain;charset=utf-8"});
saveAs(blob, "hello world.txt");

有什么技巧可以用来指定我自己的目录吗？

Answer 1

不，你不能。

[..] that is not possible due to security restrictions in the File API. The user will have to choose the directory a file is saved to.
