vuedraggable事件 - 获取组件而不是HTML元素

Question

我正在使用vuedraggable构建应用程序，并且正在拖动vue组件。所以我的问题是：是否有可能从vuedraggbale-Events而不是仅从HTML-Elements获取组件。在这里查看可排序的文档https://github.com/RubaXa/Sortable#event-object-demo我找不到这样做的方法。你有什么主意吗？ Thx you

使用change处理程序来查找数据。这里有一个最低工作例如：

const app = new Vue({ 
 
    el: '#app', 
 
    data: { 
 
    items: [ 
 
     { name: 'Alan', content: 'a' }, 
 
     { name: 'Blake', content: 'b' }, 
 
     { name: 'Chris', content: 'c' }, 
 
     { name: 'Dora', content: 'd' }, 
 
     { name: 'Ellen', content: 'e' } 
 
    ], 
 
    history: [] 
 
    }, 
 
    methods: { 
 
    afterAdd(evt) { 
 
     console.log(evt) 
 
     const element = evt.moved.element 
 
     const oldIndex = evt.moved.oldIndex 
 
     const newIndex = evt.moved.newIndex 
 
     this.history.push(`${element.name} is moved from position ${oldIndex} to ${newIndex}`) 
 
    } 
 
    } 
 
})

.dragArea { 
 
    border: solid 1px black; 
 
    background-color: grey; 
 
    min-height: 10px; 
 
} 
 

 

 

 
.document-item { 
 
    background-color: white; 
 
    border: solid 1px black; 
 
    margin: 8px 8px 8px 8px; 
 
}
