从javascript将内容添加到.txt文件

Question

Is their a way- client side, to add text to a file named text.txt in javascript?

In python:

f = open("text.txt","w")
f.write("Hello World")
f.close()

would write "Hello World" into the text file. I want to do something similar with javascript.

Note: I am running these files locally.

Its a bit more tricky than in python. The problem is that the browser sandboxes your session and your possibilities. It is possible to request storage space and read and write files in that space.

It would be a security nightmare if a javascipt file could just open files in the root or any other folder. A different approach would be to upload the file in the client/ to the server edit it and send it back in a response.
