JS Puppeteer - 如何刮桌子

Question

I am not too knowledgeable with Javascript or Puppeteer and I was wondering how to scrape the following table:

I want to scrape everything within body which are all <tr>...</tr> which have <td class="className">...</td>

Any solutions?

Answer 1

let text = await page.evaluate (() => document.querySelector('tbody').innerText)

Answer 2

That might look something like:

await page.evaluate (() => {
  return [...document.querySelectorAll('.tbrdr tbody tr')].map(tr => {
    return [...tr.querySelectorAll('td.className')].map(td => td.innerText)
  })
})
