I want to get 1 from this div tag
<div class="h5p-footer-slide-count-current" title="Current slide" aria-hidden="true">1</div>
Link javascript file and in javascript file do this
const div = document.getElementsByClassName("h5p-footer-slide-count-current")[0];
console.log(div.innerText); //your div value
document.getElementsByClassName("h5p-footer-slide-count-current")[0].innerText
That should do it
