Answer 1

This one works best for me,

function SetElementIndex(element, index) {
            var Children = $(element).parent().children();
            var target = Children[index];

            if ($(element).index() > index) {
                if (target == null) {
                    target = Children[0];
                }
                if (target != element && target != null) {
                    $(target).before(element);
                }
            } else {
                if (target == null) {
                    target = Children[Children.length - 1];
                }
                if (target != element && target != null) {
                    $(target).after(element);
                }

            }
        };
