How to number increment with limit

I am using number field with plus and minus for product quantity select for a project. I need to set a max limit when I press plus icon. I am using below code

$(document).ready(function() {
        $('.minus').click(function () {
            var $input = $(this).parent().find('input');
            var count = parseInt($input.val()) - 1;
            count = count < 1 ? 1 : count;
            $input.val(count);
            $input.change();
            return false;
        });
        $('.plus').click(function () {
            var $input = $(this).parent().find('input');
            $input.val(parseInt($input.val()) + 1 );
            $input.change();
           
            return false;
        });
    });
