how to get second last element using java script

I have a drop down of 7 options. I need to get the value of second last option using java script. I wrote something but it is not working .

$('.checkbox4').on('click', function(e) {
    var last_chekbox4 = $('.checkbox4:last.prev()');
    if (last_chekbox4.is(':checked')) {
        $('.checkbox4').prop('checked', false);
        $(this).prop('checked', true);
    }
});

Use prev() method

$('.checkbox4:last').prev()

If there is some other element in between then use

$('.checkbox4:last').prevAll('.checkbox4').first()

FYI : Above methods don't work if elements are not siblings.

UPDATE : Or get the last within the collection which excluded the last one using :not() and jQuery :last.

$('.checkbox4:not(:last):last')

Or by the index using eq() method.

var $col = $('.checkbox4');
// get element by index, where index starts from 0
var $ele = $col.eq($col.length - 2);

You have 7 elements. Use nth-of-type selector

$(".checkbox4:nth-of-type(6)");

To select the second last option
