如何通过FullCalendar中的选项卡菜单将事件拖到另一个日历

如何解决如何通过FullCalendar中的选项卡菜单将事件拖到另一个日历

我在标签容器中有一些日历，并通过导航菜单进行切换。我想通过导航菜单将事件拖动到另一个日历，当我拖动事件以及在导航菜单切换时，我丢失事件并得到错误“无法读取未定义的属性'isWithinClipping'。”当我返回到旧选项卡时，我在右上角看到了事件克隆。 html：

<div id='container'>
  <ul class="nav nav-tabs" id="myTab" role="tablist">
  <li class="nav-item" role="presentation">
    <a class="nav-link active" id="home-tab" data-toggle="tab" href="#home" role="tab" aria-controls="home" aria-selected="true">calendar 1</a>
  </li>
  <li class="nav-item" role="presentation">
    <a class="nav-link" id="profile-tab" data-toggle="tab" href="#profile" role="tab" aria-controls="profile" aria-selected="false">calendar 2</a>
  </li>
</ul>
<div class="tab-content" id="myTabContent">
  <div class="tab-pane fade show active" id="home" role="tabpanel" aria-labelledby="home-tab">
    <div id='source-calendar'></div>
  </div>
  <div class="tab-pane fade" id="profile" role="tabpanel" aria-labelledby="profile-tab">
    <div id='destination-calendar'></div>
  </div>
</div>
</div>

js代码：

var srcCalendarEl = document.getElementById('source-calendar');
  var destCalendarEl = document.getElementById('destination-calendar');

  var srcCalendar = new FullCalendar.Calendar(srcCalendarEl,{
    editable: true,droppable: true,initialDate: '2020-09-12',events: 'https://fullcalendar.io/demo-events.json?overload-day',eventLeave: function(info) {
      console.log('event left!');
    }
  });

  var destCalendar = new FullCalendar.Calendar(destCalendarEl,{
    initialDate: '2020-09-12',editable: true,// will let it receive events!
    eventReceive: function(info) {
      console.log('event received!');
    }
  });

document.addEventListener('DOMContentLoaded',function() {
  srcCalendar.render();
  destCalendar.render();
});
  

$('a[data-toggle="tab"]').on('shown.bs.tab',function (e) {
  srcCalendar.render();
  destCalendar.render();
});

$(".nav-link").on('mouseenter',function(e){
$(this).tab('show');
})

因此，有人告诉我如何通过FullCalendar中的选项卡菜单将事件拖到另一个日历吗？有什么想法。

解决方法

因此，我为我的任务找到了解决方案，为此，我将FullCalendar的源代码链接起来（非常困难）。 首先需要做的是，必须在getMirrorEl方法的ElementMirror类中的文档主体之前创建事件镜像克隆

ElementMirror.prototype.getMirrorEl = function () {
    var sourceElRect = this.sourceElRect;
    var mirrorEl = this.mirrorEl;
    if (!mirrorEl) {
        mirrorEl = this.mirrorEl = this.sourceEl.cloneNode(true); // cloneChildren=true
        // we don't want long taps or any mouse interaction causing selection/menus.
        // would use preventSelection(),but that prevents selectstart,causing problems.
        mirrorEl.classList.add('fc-unselectable');
        mirrorEl.classList.add('fc-dragging');
        applyStyle(mirrorEl,{
            position: 'fixed',zIndex: this.zIndex,visibility: '',boxSizing: 'border-box',width: sourceElRect.right - sourceElRect.left,height: sourceElRect.bottom - sourceElRect.top,right: 'auto',bottom: 'auto',margin: 0
        });
        //this.parentNode.appendChild(mirrorEl);
        document.body.appendChild(mirrorEl); // I don't no why not event clone realy create before body?
    }
    return mirrorEl;
}

第二个：由于此原因，当事件通过选项卡菜单fullCalendar拖动到另一个日历时，HitDragging类将获得新的droppableStore列表，但不会更新offsetTrackers列表。对于解决方案，我只调用方法this.prepareHits（）;。进行更新：

HitDragging.prototype.queryHitForOffset = function (offsetLeft,offsetTop) {
    this.prepareHits(); // for update offsetTrackers list
    var _a = this,droppableStore = _a.droppableStore,offsetTrackers = _a.offsetTrackers;
    var bestHit = null;
    for (var id in droppableStore) {
        var component = droppableStore[id].component;
        var offsetTracker = offsetTrackers[id];
        if (offsetTracker.isWithinClipping(offsetLeft,offsetTop)) {
            var originLeft = offsetTracker.computeLeft();
            var originTop = offsetTracker.computeTop();
            var positionLeft = offsetLeft - originLeft;
            var positionTop = offsetTop - originTop;
            var origRect = offsetTracker.origRect;
            var width = origRect.right - origRect.left;
            var height = origRect.bottom - origRect.top;
            if (
            // must be within the element's bounds
            positionLeft >= 0 && positionLeft < width &&
                positionTop >= 0 && positionTop < height) {
                var hit = component.queryHit(positionLeft,positionTop,width,height);
                console.log('hit',hit)
                if (hit &&
                    (
                    // make sure the hit is within activeRange,meaning it's not a deal cell
                    !component.props.dateProfile || // hack for DayTile
                        rangeContainsRange(component.props.dateProfile.activeRange,hit.dateSpan.range)) &&
                    (!bestHit || hit.layer > bestHit.layer)) {
                    // TODO: better way to re-orient rectangle
                    hit.rect.left += originLeft;
                    hit.rect.right += originLeft;
                    hit.rect.top += originTop;
                    hit.rect.bottom += originTop;
                    bestHit = hit;
                }
            }
        }
    }
    return bestHit;
};

也许这不是一个很好的解决方案，但确实可行。我希望FullCalendar的开发人员可以添加此功能。
