验证minDate引导日期时间选择器格式（HH：mm）

Question

我正在系统中使用引导日期时间选择器功能。

，第一个datetimepicker格式为YYYY-MM-DD，第二个datetimepicker格式为HH:mm。

我尝试以下验证：当第一个datetimepicker选择日期时，第二个datetimepicker minDate将成为HH:mm格式的选择日期。
               但是失败了： 我在今天设置了第一个datetimepicker minDate，并且在尝试使用minDate库时，第二个datetimepicker验证moment()失败：

 $('#datetimepicker5').datetimepicker({
        format: 'L',
        showTodayButton: true,
        minDate: new Date()-1,
        format: 'YYYY-MM-DD'
    }).on('dp.change', function(e) {

            var fromDate =    $("#datetimepicker5").data("date");
            var chosenTime =  $("#datetimepicker6").data("date");

            if(moment(moment(e.date).format( 'YYYY-MM-DD'), 'YYYY-MM-DD',true).isValid()){
                  if( moment(e.date).isSame(formatDate(new Date)) ){
                    alert("SAME DATE")
                    console.log("SAME DATE")
                    var nowTime =  moment().format('HH:mm');
                    if(nowTime  > formatHourAndMinute(new Date (0, 0, 0, chosenTime.split(":")[0],chosenTime.split(":")[1]))){
                          $('#datetimepicker6').data("DateTimePicker").date(nowTime);
                          $('#datetimepicker6').data("DateTimePicker").minDate(nowTime);
                    }
                }      
            }else{
                alert(" Sorry the date you selec is not valid.");
                $scope.dateTimePickerFailed = false;
            }
    });

    $('#datetimepicker6').datetimepicker({
        format: 'HH:mm',
        showTodayButton: true,
        minDate:   $("#datetimepicker5").data("date"),

    }).on('dp.change', function(e) {
         var beginningTime = moment({h: +e.date.format('HH'), m: +e.date.format('mm')});
          var nowTime = moment().format('HH:mm');

          var choosenDate =    $("#datetimepicker5").data("date");
          var chosenTime =  $("#datetimepicker6").data("date");
             var selectedTime = $("#selectedTime").val();

             if(moment(moment(e.date).format( 'HH:mm'),'HH:mm',true).isValid()){

                    if( moment(choosenDate).isSame(formatDate(new Date)) ){
                        if(nowTime  > formatHourAndMinute(new Date (0, 0, 0, chosenTime.split(":")[0],chosenTime.split(":")[1])) ){
                              $('#datetimepicker6').data("DateTimePicker").date(nowTime);
                              $('#datetimepicker6').data("DateTimePicker").minDate(nowTime);
                        }
                    }   
             }else{
                    alert(" Sorry the date you selec is not valid.");
                    $scope.timePickerFailed = false;
                }        

        });
    function formatHourAndMinute(date) {
        var d = new Date(date),
            hour = '' + parseInt(d.getHours()+1),
            minute = '' + d.getMinutes();

        if (hour.length < 2) hour = '0' + hour;
        if (minute.length < 2) minute = '0' + minute;

        return [hour, minute].join(':');
    }
    function formatDate(date) {
        var d = new Date(date),
            month = '' + (d.getMonth() + 1),
            day = '' + d.getDate(),
            year = d.getFullYear();

        if (month.length < 2) month = '0' + month;
        if (day.length < 2) day = '0' + day;

        return [year, month, day].join('-');
    }

这是HTML：
