How to copy a section of code in jquery, replace the contents of the block in it and paste it somewhere else?

Question

JavaScript

You need to copy a section of code, replace the contents of the block in it (by the selector) and get its ready-made code (of type newCode.html();)
How to implement this? I tried to clone, find and replace the value in it and get the html() of this clone, but the html remains the same

Answer 1

Maybe so?
var clone = $('.box .ch').clone().val('2');
$('.box2').html(clone);
If only the value needs to be inserted, then
var clone = $('.box .ch').clone().val('2');
$('.box2').html(clone.val());
