Check if td element have certain value

i have a table with number :

<td id="table-number">{{ $loop->index + 1 }}</td>

now i want to get the number of "9" from the table row

Here is what i do :

const number = document.getElementById('table-number');


if(number.textContent.includes('9')) {
            console.log('heyhey');
        }

but it returns nothing. So, what should i do? I expect to get the table number.

ok guys, i got the answer at this post, sorry i didnt serach thoroughly. Need to upgrade my google skils

>Solution :

Assuming the <td> elements are produced in a loop and you want to know if any of them contain a 9, give the elements a class instead of id…

<td class="table-number">

and try something like this instead

const tableNumbers = Array.from(
  document.querySelectorAll(".table-number"),
  ({ textContent }) => textContent
);

if (tableNumbers.some((content) => content.includes("9"))) {
  console.log("heyhey");
}
