The first delete produced works fine when clicked on "add more" but del element produced after that deletes everything present on the page. Can someone please help me, maybe something is wrong with ele, I don't have much experience with JS
Steps to reproduce :
Click on add more and then the next add more which got created on click the previous add more.
click on the last del
It deletes everything rather than deleting that very DIV
$(function() {
$(".btn-copy").on('click', function() {
var ele = $(this).closest('.example-2').clone(true);
ele.find('input').val('')
if (ele.find('button').length<2) {
let btn = document.createElement("button");
btn.innerHTML = "Delete";
btn.onclick = (e) => {
e.preventDefault()
ele.remove()
}
ele[0].appendChild(btn);
}
$(this).closest('.example-2').after(ele);
})
})

The problem was in the use of .clone()
You where cloning the latest cloned element which forced you to create an if statement to prevent creating more than one delete button. But that also did not allow you to execute what was inside the if statement after a certain number of nodes cloned.
You also could not use the btn variable outside that if statement.
The solution is to clone always the first example-2element so we can jump the use of the if statement and allow the btn variable to be used freely.
I added an extra div #wrapper to use find('div').first() so the same example-2 element can be copied every time.
$(function() {
$(".btn-copy").on('click', function() {
var ele = $('#wrapper').find('div').first().clone(true);
ele.find('input').val('');
let btn = document.createElement("button");
btn.innerHTML = "Delete";
ele[0].appendChild(btn);
btn.onclick = (e) => { ele.remove() };
$(this).closest('.example-2').after(ele);
})
})
