showing in jquery invalid date?

Question

$(function () {
    debugger;
    var nowTemp = new Date();
    var now = new Date(nowTemp.getFullYear(), nowTemp.getMonth(), nowTemp.getDate(), 0, 0, 0, 0);
    var checkin = $('#_startdate').datepicker({
        language: 'en-US',
        onRender: function (date) {
            debugger;
            return date.valueOf() < now.valueOf() ? 'disabled' : '';
        }
    }).on('changeDate', function (ev) {
        if (ev.date.valueOf() > checkout.date.valueOf()) {
            var newDate = new Date(ev.date)
            newDate.setDate(newDate.getDate() + 1);
            checkout.setValue(newDate);
        }
        checkin.hide();
        $('#_enddate')[0].focus();
    }).data('datepicker');

    var checkout = $('#_enddate').datepicker({
        onRender: function (date) {
            return date.valueOf() <= checkin.date.valueOf() ? 'disabled' : '';
        }
    }).on('changeDate', function (ev) {
        checkout.hide();
    }).data('datepicker');
}); 

I am trying to run this code but, var nowTemp = new Date(); shows an invalid date and I don't know why? Any suggestions?

Answer 1

You are creating an empty date with new Date()

If you want the current date you can use $.now()

Answer 2

nothing to worry about. But if you want the actual reason, look at the CMS note on this answer : https://stackoverflow.com/a/9725453/2143734
