Chrome DevTools。 自动将控制台输出保存到文件

Question

I try to get text content from the webpage. For example Google.com

I write at console:

$ ('#SIvCob').innerText

and get:

"Google offered in: русский"

This is the text, what I find out. Now I want to save it to file (.txt).

Two moments: there is no only one item, that I search, actually 7-10. And, there is a refresh every second! I go to write a cycle.

I know about copy() function and about right click on the console and "Save As," but I need a CODE, which will do it automatically.

Thanks in advance.

The browser has no API to write to the file system since that would be a security risk. But you can use Nodejs and their File System API to write you text file.

You will also need to use the HTTP API to get the web content. And you will also need to parse your HTML, you can do it with fast-html-parser or any other module of your choice. (high5, htmlparser, htmlparser2, htmlparser2-dom, hubbub, libxmljs, ms/file, parse5, ...)

 var http = require('http');
 var fs = require('fs');
 var parser = require('node-html-parser');
 var options = {
   host: 'www.google.com',
   port: 80,
   path: '/index.html'
 };
 var file = '/path/to/myFile.txt';
 http.get(options, function(res) {
   res.setEncoding('utf8');
   var body = ''; 
   res.on('data', function (chunk) {body += chunk});
   res.on('end', function () { 
     var dom = parser.parse(body);
     var text = dom.querySelector('#SIvCob').text;
     fs.writeFile(file, text, function (err) {
       if (err) throw err;
       console.log('The file has been saved!');
     });
   });
 });
