日期选择器-禁用将来的日期范围

Question

I have been trying to implement some additional code to disable a range of dates in the future on my date range picker, from my research I believe I need to use beforeShowDay , have the dates in an array and return a false if the dates are in the array but each time I try to spanner in some code it breaks the pickers. I have to confess I don't know Javascript very well at all and only use it with plugins when I have to, any help would be gratefully received.

var dateToday = new Date();
var dates = $("#from, #to").datepicker({
defaultDate: "+1w",
changeMonth: true,
numberOfMonths: 1,
minDate: dateToday,
onSelect: function(selectedDate) {
    var option = this.id == "from" ? "minDate" : "maxDate",
        instance = $(this).data("datepicker"),
        date = $.datepicker.parseDate(instance.settings.dateFormat || $.datepicker._defaults.dateFormat, selectedDate, instance.settings);
    dates.not(this).datepicker("option", option, date);
}
});

I would like to disable from the 2nd of December 2017 to the January 27th 2018

 $('#datePick').datepicker({ defaultDate: "+1w", changeMonth: true, numberOfMonths: 1, minDate: new Date(), beforeShowDay: function(date){ var val = new Date("2017-12-02") >= date || new Date("2018-01-28") < date ; return [ val ] } });

use beforeShowDay and check which date you need to show.
