获取目标元素ondrop事件的data-id属性

Question

很明显，事件对象非常庞大且难以导航。我试图使用ondrop事件获取我的目标元素的data-id属性。所以

onItemDrop(event: any) {
    // Get the dropped data here
    console.log(event.///GET THE data-id attribute of the target element);
}

html：

<div id="{{ column.id }}"
    class="board-body"
    data-id="{{ column.id }}"
    (onDrop)="onItemDrop($event)"
    droppable>
    <div class="card bg-light-blue mb-2" *ngFor="let item of (results | groupBy: column.id)" [dragData]="item" draggable>
        <div class="card-body">
            <div class="card-title mb-0">
                <h6>
                    <span class="text-primary"><strong>{{ item.contactName }}</strong></span>
                    <span class="text-secondary">- {{ item.mediaOutletName }}</span>
                </h6>
                <button class="btn btn-transparent p-0">
                    <small><i class="fa fa-caret-down p-0"></i></small>
                </button>
            </div>
            <div class="card-text text-dark">
                Sent: {{ item.updatedDate | date }}
            </div>
        </div>
    </div>
</div>

我需要这个，因为如果项目删除了id，那么我将添加到脚本中来更改数据，以便它匹配它被放入的元素的id？
