How to create/write into a local txt file using Javascript or jQuery but no webserver

Question

I'm working on a project where I need to store the data in files next to the html-file but it needs to be runnable even without internet, and without any local web server.

Could somebody tell me how to create/write a txt file what I'll use as script in my html?

Answer 1

Build your app using Electron (or NW.js ) and use Node's filesystem module to write your text file:

const { writeFile } = require('fs');

const data = 'Some text';

writeFile('data.txt', data, (error) => {
  console.log(error || 'Done!');
});

Answer 2

严重的是，即使没有Web服务器，即使在html文件所在的目录中，我也无法在计算机上创建文件？
