推荐答案

出于安全原因，JavaScript无法做到这一点.您无法在客户端计算机上创建文件，因为JavaScript在该环境中没有写权限.

That is not possible with JavaScript for security reasons. You cannot create files on the client machine, since JavaScript doesn't have write permission in that environment.

作为解决方法，您可以通过Ajax请求将要存储的文本发送到Web服务器，该Web服务器又可以生成文本文件供用户下载到所需的位置..不太平滑，但至少可以解决.

What you could do as a work around is to send the text that you want to store through an Ajax-request to the web server, which in turn can generate a the text-file for the user to download to a desired location. Not as smooth, but at least it is a work around.
