Question

I have an element which I need to append into other element, and after some other manipulation I need to put element back to its default position.

Answer 1

Save the object’s parent with .data() and retrieve it when you move it back.

$( '#move' ).data( 'originalParent', $( '#move' ).parent() );  

// moving to new position
$( '#moveToNew' ).click( function() {
    $( '#move' ).appendTo( '#new' );
});

// move element back to where it was
$( '#moveBack' ).click( function() {
    $( '#move' ).appendTo( $( '#move' ).data( 'originalParent' ) );
});
