为Datepicker jQuery问题设置自定义minDate

我想为我的约会挑选者建立一个定制minDate。 我从输入中获取自定义日期值：

var currentScheduledDate = jQuery("#scheduled_at").val();

我想将日期选择器设置为从自定义日期+3天开始

这些是我的情妇：

            {
                closeText: "Schließen",
                prevText: "<Zurück",
                nextText: "Vor>",
                currentText: "Heute",
                monthNames: [ "Januar","Februar","März","April","Mai","Juni",
                    "Juli","August","September","Oktober","November","Dezember" ],
                monthNamesShort: [ "Jan","Feb","Mär","Apr","Mai","Jun",
                    "Jul","Aug","Sep","Okt","Nov","Dez" ],
                dayNames: [ "Sonntag","Montag","Dienstag","Mittwoch","Donnerstag","Freitag","Samstag" ],
                dayNamesShort: [ "So","Mo","Di","Mi","Do","Fr","Sa" ],
                dayNamesMin: [ "So","Mo","Di","Mi","Do","Fr","Sa" ],
                weekHeader: "KW",
                isRTL: false,
                showMonthAfterYear: false,
                yearSuffix: "",
                minDate: currentScheduledDate.getDate()+3,
                maxDate: "+3M" ,
                dateFormat : "dd-mm-yy",
                beforeShowDay: jQuery.datepicker.noWeekends,
                firstDay: 1
            }

显然，这是行不通的：

minDate: currentScheduledDate.getDate()+3,

你知道怎么设置吗？谢谢你

当你说它不工作时，有什么错误吗？我们可以得到您的值吗？如果有用，请检查@Baptiste我遇到了以下错误：

currentScheduledDate.getDate不是函数
