vue elementui tree 任意级别拖拽功能代码

我的是根据父级id做的一些判断

 
   allowDrop(draggingNode, dropNode, type){
   //注掉的是同级拖拽
   
   //任意级别拖拽
   if (draggingNode.data.aboveId === dropNode.data.aboveId) {
     return type === 'prev' || type === 'next'
   } else {
    return type === 'prev' || type === 'next' || type === 'inner'
   }
  },
  //拖拽完成之后要重新排序
  
  sort(draggingNode,dropNode,type,event) {
   console.log(draggingNode)
   console.log(dropNode)
   if (draggingNode.data.aboveId === dropNode.data.aboveId) {
    let obj = {
     aboveId:'',
     arr:[]
    }
    obj.aboveId = dropNode.data.aboveId
    for (let item of dropNode.parent.childNodes) {
     obj.arr.push(item.data.id)
    }
    console.log(obj)
    this.updateOrderMe(obj)
   } else {
    let obj = {
     aboveId:'',
     id:'',
     newAboveId:''
    }
    obj.aboveId = draggingNode.data.aboveId
    obj.id = draggingNode.data.id
    obj.newAboveId = dropNode.data.id
    this.randomDrag(obj)
   }
  },
  randomDrag(obj) {
   this.$http
    .post(url, obj).then(res =>{
	    if (!res.data.success) {
	     this.$message.warning(res.data.msg)
	    }
    })
  },
  updateOrderMe(obj) {
   this.$http
    .post(url, {
     aboveId:obj.aboveId,
     ids: obj.arr
    }).then(res =>{
	    if (!res.data.success) {
	     this.$message.warning(res.data.msg)
	    }
    })
  }

补充知识：element-ui tree 实现同级拖拽

我就废话不多说了，大家还是直接看代码吧~
