How do you clone an element and change the ID's of it and all its children to be unique? [SOLVED]


I'm trying to duplicate a fieldset, I have managed to get the cloning process.

But now, I want to edit all of its ID's from id="hello" to id="hello-2"

The code I'm trying below just doesn't work and I don't know why! (It's the middle section that is broken).

//When add section is pressed
$('#add-section').click(function () {
    // get the fieldset's children that user is on, and clone it
    var $fieldsetCopy = $('form>:nth-child(' + pageNumber + ')').clone();

    // add '-2' to all id's of the cloned fieldset
    $fieldsetCopy.find("*[id]").each(function () {
        $(this).attr("id", $(this).attr("id") + "-2");

    // add the cloned fieldset within the original
    $fieldsetCopy.appendTo('form>:nth-child(' + pageNumber + ')');


Thanks for posting your solution!
