I am trying to scrape the key features part of the website with the URL of: "https://www.alpinestars.com/products/stella-missile-v2-1-piece-suit-1" using puppeteer - however, whenever I try to use a selector that works on the chrome console for the website the output for my code is always an empty array or object. For example both document.querySelectorAll("#key\ features > p") and document.getElementById('key features') both return as empty arrays or objects when I output it through my code but work via chrome console.
I have attached my code below:
const puppeteer = require('puppeteer');
async function getDescripData(url) {
const browser = await puppeteer.launch({headless: true});
const page = await browser.newPage();
await page.goto(url);
const descripFeatures = await page.evaluate(() => {
const tds = Array.from(document.getElementById('key features'))
console.log(tds)
return tds.map(td => td.innerText)
});
console.log(descripFeatures)
await browser.close();
return {
features: descripFeatures
}
}
How should I go about overcoming this issue?
Thanks in advance!
Your problem is in Array.from you are passing a non-iterable object and return null.
This works for me:
const puppeteer = require('puppeteer');
const url = 'https://www.alpinestars.com/products/stella-missile-v2-1-piece-suit-1';
(async () => {
const browser = await puppeteer.launch({
headless: false,
defaultViewport: null,
args: ['--start-maximized'],
devtools: true
});
const page = (await browser.pages())[0];
await page.goto(url);
const descripFeatures = await page.evaluate(() => {
const tds = document.getElementById('key features').innerText;
return tds.split('• ');
});
console.log(descripFeatures)
await browser.close();
})();
