vue使用vue-draggable的全过程

npm install vuedraggable --save

import draggable from 'vuedraggable'

export default {
  components: {
    draggable
  }
}

<draggable v-model="list" :options="dragOptions">
  <div v-for="item in list" :key="item.id">{{ item.name }}</div>
</draggable>

data () {
  return {
    list: [
      {id: 1, name: 'item1'},
      {id: 2, name: 'item2'},
      {id: 3, name: 'item3'}
    ]
  }
}

dragOptions: {
  animation: 200, // 动画时间，单位毫秒
  group: 'items', // 分组，同一分组内的元素可以互相拖拽
  disabled: false, // 是否禁用拖拽功能
  ghostClass: 'ghost', // 拖拽过程中占位元素的class名称
  handle: '.handle', // 拖拽手柄，只有拖拽手柄内的元素才能被拖拽
  sort: true, // 是否启用排序功能
  draggable: '.item', // 可拖拽元素的选择器
  filter: '.ignore' // 不可拖拽元素的选择器
}

methods: {
  onEnd (evt) { // 拖拽结束时触发
    console.log('onEnd', evt)
  },
  onMove (evt) { // 拖拽过程中触发
    console.log('onMove', evt)
  },
  onStart (evt) { // 开始拖拽时触发
    console.log('onStart', evt)
  }
}
