Cloning parent and its first + last child in jQuery - html

Question

Say I have the following the markup:
$('button').click(function() {
let row = $('div.row');
let clonedRow = row.clone(true);
clonedRow.appendTo('body');
});
.row {
border: 1px solid black;
margin-bottom: 5px;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<button>append</button>
<div class="row">
<div class="first">append me!</div>
<div class="item">DONT append me</div>
<div class="item">DONT append me</div>
<div class="last">append me!</div>
</div>
I can achieve this by using clone() multiple times, but I'm looking for a clean solution that can do it with as little methods/functions as possible. Has to be in jQuery and not vanilla JS.

Answer 1

You can use the remove() method to remove the .item elements from the cloned content:
$('button').click(function() {
let $row = $('div.row:first').clone(true);
$row.find('.item').remove();
$row.appendTo('body');
});
.row {
border: 1px solid black;
margin-bottom: 5px;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<button>append</button>
<div class="row">
<div class="first">append me!</div>
<div class="item">DONT append me</div>
<div class="item">DONT append me</div>
<div class="last">append me!</div>
</div>

First you have to select row, then clone that row & then remove .items elements from that content by remove() method & then append that to the body.
$('button').click(function(e) {
e.preventDefault();
let row = $('div.row:first');
let clonedRow = $(row).clone(true);
$(clonedRow).find("div.item").remove();
$(clonedRow).appendTo('body');
});
