Creating HTML/Javascript Modal with dynamic text
See here for the original answer.
The problem with your code is that you are attempting to access the entirety of the querySelectorAll array instead of the individual element that you are interested in. See the code below for an example of a way to resolve this:
for (let i = 0; i < btnsOpenModal.length; i++) {
btnsOpenModal[i].addEventListener("click", function () {
const modalText = btnsOpenModal[i].id;
if (text[i].classList.contains(modalText)) {
text[i].classList.remove("hidden");
}
modal.classList.remove("hidden");
overlay.classList.remove("hidden");
});
}
