having trouble getting data from puppeteer .innertext js

im having trouble getting the text that is listed in the element. I thought I did it right but i keep getting errors. This is the Element im trying to get. Any help would be great. Cant link the site because you have to login to get to this page.

<p><span class="query-player_current">1</span>
/
<span class="query-player_max">32</span></p>

(Trying to get the "1" and "32")^

and this is the code that i have.

const result = await page.evaluate (() => {
        let playerCount = document.querySelector('query-player_current').innerText;
        let playerCountMax = document.querySelector('query-player_max').innerText;
        return {
            playerCount,
            playerCountMax
        }
    })

this is the errors im getting

Solution

  • You have to use '.' as prefix, If you are using classnames in query. try

     document.querySelector('.query-player_current')
 document.querySelector('.query-player_max')
