有幸用过这个ant组件  一言难尽！！ 了解到这个组件默认不透露父节点信息 所以处理是真的麻烦 ，我这个需求是选中子节点要把它的父节点展示出来！开始用了很多捷径都没成功，最后用循环加递归踏踏实实的去找到它的父节点

 代码段：html

  <a-tree
              v-if="treeData.length"
              show-search
              :checkedKeys="checkedKeys"
              :treeData="treeData"
              checkable
              :selectable="false"
              v-model="selectedKeys"
              @select="onSelect"
              @check="onCheck"
            >
              <template slot="name" slot-scope="{ name }">
                <span v-html="name.replace(new RegExp(searchValue, 'g'), '<span style=color:#f50>' + searchValue + '</span>')"></span>
              </template>
            </a-tree>

js:

//获取父节点
    onCheck(checkedKeys) {
        var tempArr = [];
        if(this.checkedKeys.length>0){
            console.log(this.checkedKeys[0].split("-"))
            for(let a=0;a<this.checkedKeys.length;a++){
                var tempA =  this.checkedKeys[a].split("-");
                var index = 0;
                var tempStr = "";
                var data = this.treeData[0];
                var id = 0;
                var temFuc = ()=>{
                    index++;
                    if(tempA.length-index>=0){
                        console.log(index)
                        if(tempStr){
                            tempStr = tempStr+"-"+data.name;
                        }else{
                            tempStr = data.name;
                        }
                        if(data.children){
                            data = data.children[tempA[index]];
                        }else{
                            id = data.id;     
                        }
                        temFuc();
                    }
                }
                temFuc();
                tempArr.push({
                    text:tempStr,
                    keys:this.checkedKeys[a],
                    id:id
                })
            }
            this.checkedList = tempArr;
        }
       console.log(this.checkedKeys)
    },

可以拿到以下俩组数据：
