How to save a file into Downloads in a Chrome extension?

Firstly, add these to manifest.json:

{
  "manifest_version": 2,
  "name": "Chrome extension example 1",
  "permissions": [
      "downloads"
  ],
  "content_scripts": [
      {
          "matches": ["*://www.google.com/"],
          "run_at": "document_idle"
      }
  ],
  "background": {
      "scripts": ["background.js"],
      "persistent": false
  },
}

Secondly, add these to background.js: ```javascript /* jshint esversion: 6 / / jshint node: true */ ‘use strict’;

console.log(“===== Enter background.js ======”); const url = ‘data:text/html;charset=utf-8,’ + ‘<html>test</html>’; chrome.downloads.download({ url: url, filename: ‘0_test.html’ }); console.log(“===== 0_test.html saved to Downloads folder. ======”); ```

Thirdly, verify the result. Whenever you visit www.google.com, you should see 0_test.html is saved into Downloads folder.
