What i need is when i select two or more rooms to clone the area that is commented From here - To here

I have arleady a similar code but is for kids age The cpde that o have for kids age is:

    // handle kid age filter
tjq('select[name=kids]').change(function(){
    var prev_kids = tjq('.age-of-children .child-age-field').length;
    tjq('.age-of-children').removeClass('no-display');
    var i;
    if (prev_kids > tjq(this).val()) {

        var current_kids = tjq(this).val();

        if (current_kids == 0) {
            current_kids = 1;
            tjq('.age-of-children').addClass('no-display');
        }

        for (i = prev_kids; i > current_kids; --i) {
            tjq('.age-of-children .child-age-field').eq(i-1).remove();
        }
    } else {
        for (i = prev_kids + 1; i <= tjq(this).val(); i++) {
            var clone_age_last = tjq('.age-of-children .child-age-field:last').clone();
            var clone_age = clone_age_last.clone();
            tjq('.age-of-children .row').append(clone_age);
            var name = clone_age.find('label').text().replace(/(\d+)/, function(match, p1)
            {
                return (parseInt(p1) + 1);
            });
            clone_age.find('label').text(name);
            clone_age.find('select').val(0);
            clone_age.find('.custom-select').text(0);
        }
    }
});

Hope to get this sorted out,

Answer 1

i would do it that way:

1) wrap an additional div arround your "from here/to here" eg with the class "additionalRoom"

2) change event on your room number select and get the number with $(this).val(); ( http://api.jquery.com/change/ )

3) copy your additionalRoom div with clone() and insert it x times based on the chosen rooms number at the wanted position ( http://api.jquery.com/clone/ )

4) and i would change the room form part that way that the same html could simply be cloned and resulting the form data in a good way. eg name="roomAdults[]", name="roomKids[]" or you have the room data as numbered array (room[1][adults], room[2][kids]). in the last case you have to increase this number after cloning and before inserting
