Click on random Google Search result using NodeJS and Puppeteer?

I'm attempting on making a small script to click on a random Google Search result after searching "'what is ' + Word." Nothing I've done has been able to get me the results I want, heck, I can't even get the script to click a single Google Search result!

I've tried doing multiple things here, such as collecting all search results in an array and clicking a random one (didn't collect into an array), clicking an element by partial text (https:// brought no results), and many other solutions that work in Python, but don't work here.

const puppeteer = require('puppeteer');
const searchbar = "#tsf > div:nth-child(2) > div > div.RNNXgb > div >   div.a4bIc > input"



async function gsearch() {
const browser = await puppeteer.launch({headless:false, args:['--no-sandbox', '--disable-setuid-sandbox']});
const page = await browser.newPage();

await page.goto('https://google.com');
 var fs  = require("fs");
var array = fs.readFileSync("words.txt").toString().split('\n');
var random = array[Math.floor(Math.random() * array.length)]
await page.click(searchbar)
await page.keyboard.type("what is " + random);
await page.waitFor(1000);
await page.evaluate(() => {
  let elements = $('LC20lb').toArray();
  for (i = 0; i < elements.length; i++) {
    $(elements[i]).click();


  } 
 })
}

gsearch();

(ignore any indent-inheritant errors, I swear it looks cleaner in VSC)

Expected to click a random search result. End up getting nothing done, maybe an error or two but that's about it.

Solution

LC20lb is not html tag and it should be class name for h3 and by using$() are you trying to select elements with jQuery? use document.querySelectorAll() instead.

const puppeteer = require('puppeteer');
const fs = require("fs");

async function gsearch() {
  const browser = await puppeteer.launch({
    headless: false,
    args: ['--no-sandbox', '--disable-setuid-sandbox']
  });
  const page = await browser.newPage();

  await page.goto('https://google.com');
  var array = fs.readFileSync("words.txt").toString().split('\n');
  var random = array[Math.floor(Math.random() * array.length)];
  // simple selector for search box
  await page.click('[name=q]');
  await page.keyboard.type("what is " + random);
  // you forgot this
  await page.keyboard.press('Enter');
  // wait for search results
  await page.waitForSelector('h3.LC20lb', {timeout: 10000});
  await page.evaluate(() => {
    let elements = document.querySelectorAll('h3.LC20lb')
    // "for loop" will click all element not random
    let randomIndex = Math.floor(Math.random() * elements.length) + 1
    elements[randomIndex].click();
  })
}
