I have a django-qcm with sections that change when clicking on anchors and using the scroll snap type property.

function scrollToAnchor(ind){
const aTag = $("#"+ind);
$('body,section').animate({scrollTop: aTag.offset().top},'slow');
}
//scrollToAnchor('2');
var container_page = document.getElementsByClassName('container')
const reps = document.getElementsByClassName('rep');
[].forEach.call(reps,function(rep){
$(rep).click(function(){
if(! rep.querySelector('.check')){
[].forEach.call(reps,function(repToDel){
if(repToDel.querySelector('.check')){
repToDel.querySelector('.check').remove()
$(repToDel).css("border", "1px solid white")
}
})
$(rep).last().append('<div class="check"><object data="{% static "img/Coin-Magpharm-V3.png" %}" width="20" > </object></div>');
$(rep).css("border", "2.5px solid white");
let x = parseInt($(rep).closest('.container').attr('id'))
//var y = x.toString()
console.log(x)
scrollToAnchor(x+1)
}
})
})
</script>
</body>
</html>
The first anchor works fine, but after the second nothing happens. The function scrollToAnchor(3) works fine when called in the console.
I tried to change different dom parameters to reach the container id and the int and str but nothing changes except errors.

.Try something like this:
