Question

How can i insert a div element with dynamic ID inside another div element using
JQuery?

Answer 1

if you want to create that div:

$('<div></div>').attr('id','my-funky-id').appendTo('parentselector');
// or
$('parentSelector').append($('<div id="'+my_id+'">'));/// my_id = var holding the id  

if you already have that div, but you want to insert it into another element (move it) :

$('#'+my_id).appendTo('parentSelector');
