Vue+Element-ui el-tree 后台返回Pid,自

请求到的数据

 this.$nextTick(()=>{
     this.toTreeData(res.data.data, 'id', 'pid', 'name');
     this.resize()
 })

下面的修改对应字段,修改第一位的Pid

toTreeData(data, id, pid, name) {//找到当前组织的直系子节点
        // 建立个树形结构,需要定义个最顶层的父节点，pId是1
        // console.log(data)
        let parent = [];
        for (let i = 0; i < data.length; i++) {
          // console.log(data[i][pid] == this.myOrgId)
          if (data[i][pid] != '0') {
          } else {
            let obj = {
              label: data[i][name],
              id: data[i][id],
              children: []
            };

            parent.push(obj); //数组加数组值
            // console.log(obj);
          }
          
          //  console.log(parent,"bnm");
        }
        this.children(parent,data, id, pid, name);

        // 调用子节点方法,参数为父节点的数组
        // console.log(parent);
        // return parent;
      },
      children(parent,data, id, pid, name) {//给当前组织的直系子节点添加剩下的子节点
        // console.log(parent);
        // console.log(data);
        let _this = this;
        if (data) {
          for (let i = 0; i < parent.length; i++) {
            for (let j = 0; j < data.length; j++) {
              if (parent[i].id == data[j][pid]) {
                // console.log(data[j].name)
                let obj = {
                  label: data[j].name,
                  id: data[j][id],
                  children: []
                };
                // console.log(obj)
                parent[i].children.push(obj);
              }

            }
            // console.log(parent[i].children,data)
            _this.children(parent[i].children,data,id, pid);
          }
        }
        _this.treeData = parent
        // console.log(_this.treeData)
      },
