【问题描述】：

我想防止过去发生的事件被拖动。我试过用；

eventConstraint: {
    start: moment().format('YYYY-MM-DD'),/* This constrains it to today or later */
    end: '2100-01-01' // hard coded goodness unfortunately
},

我可以通过以下方式防止将拖到过去的日期：

eventDrop: function(info) {
    var eventObj = info.event;
    var check = moment(eventObj.start).format('YYYY-MM-DD');
    var today = moment().format('YYYY-MM-DD');
    if(check < today) {
        revertFunc(); //Put the Event back where it came from
    } else {
        //code
    }
},

完整代码：

var calendar = new FullCalendar.Calendar(calendarEl, {
        firstDay: 0, //Sunday
        weekends: true, //Show the weekends
        businessHours: { // days of week. an array of zero-based day of week integers (0=Sunday)
            daysOfWeek: [ 1, 2, 3, 4, 5 ], // Monday - Friday
            startTime: '09:00', // a start time
            endTime: '17:00', // an end time
        },
        initialView: 'dayGridMonth',
        headerToolbar: {
            left: 'prev,next today',
            center: 'title',
            right: 'dayGridMonth,timeGridWeek,timeGridDay,listMonth'
        },
        locale: 'en-gb',
        selectable: true, // gives ability to select multiple days and then have a callback event when this occurs
        buttonIcons: false, // show the prev/next text
        weekNumbers: true, // show week numbers
        navLinks: true, // can click day/week names to navigate views
        editable: true, // can make changes and add changes
        dayMaxEvents: true, // allow "more" link when too many events
        displayEventEnd: true, // display the end time
        eventTimeFormat: {
            hour: '2-digit',
            minute: '2-digit',
          },// display time with minutes
        eventDisplay: 'block', //Changes an event with start and end times from a list-item to a block
        eventConstraint: {
            start: moment().format('YYYY-MM-DD'),/* This constrains it to today or later */
            end: '2100-01-01', // hard coded goodness unfortunately
        },
        
        events: responseJson1a,//Populate Event using JSON

【解决方案1】：

在 fullCalendar 上定义过去的事件时，将 key editable 设置为 false

events: [
      {
        title: 'Business Lunch',
        start: '2021-11-03T13:00:00',
        constraint: 'businessHours',
        editable:false,
      },
      ...
      ...
]

您好，谢谢；但是，并不是我想要的。我想要所有事件的约束，所以使用 eventConstraint 不是约束。我已经用完整的代码更新了我的问题。
我想我可以使用“oldEvent”来获取原始开始日期；但是，我找不到如何使用它的示例。
