使用ng2-dragula拖放包装器库处理有角2的Dragula.
Using ng2-dragula drag and drop wrapper library for angular 2 dragula.

当物品掉落时看到[dragulaModel]='myList' ...
的问题... po ...它消失了.
Seeing issues with the [dragulaModel]='myList' ...
when the item gets dropped ... poof ... it disappears.
检查该元素后,我看到它仍然保留在模型中,但是DOM元素丢失了它的inner html
(成为空div)-导致div的外观"被隐藏了.
Inspecting the element, I see it remains in model, but the DOM element loses its inner html
(becomes empty div) - causing the div to "appear" to be hidden.

推荐答案
Welp,发现了问题所在.内部html是空白的,因为 actual DOM元素的dragula移动是内部html(元素的内容),而不是移动标记有属性[dragula]
的元素.
Welp, figured out the issue. The inner html is blank because the actual DOM element dragula moves is the inner html (element's content), instead of moving the element marked with attribute [dragula]
.
此问题已解决:
<div class='wrapper' [dragula]='"first-bag"' [dragulaModel]='fixtures'>
<div class='container' *ngFor='let fixture of fixtures'>
<div>{{fixture.id}}</div>
</div>
</div>
他们自己的文档对此不太清楚,因为它们具有:
Their own documentation is a little unclear with this, as they have:
<ul>
<li *ngFor="let item of items" [dragula]='"bag-one"' [dragulaModel]='items'></li>
</ul>
故事道德:将[dragula]
和[dragulaModel]
从放置*ngFor
的位置向上移动一个元素.
Moral of story: move your [dragula]
and [dragulaModel]
UP one element from where you put your *ngFor
.
