将对象级别的json对象转化为elementui框架tree控件支持的数据格式

//格式化树将带node,children节点的json对象转化为符合elementui树控件所需要的数据格式
    formatTreeData(data) {
      let result = [];
      if (data.length > 0) {
        for (let i = 0; i < data.length; i++) {
          let node = data[i].node; //每一个节点
          let children = data[i].children; //对应的孩子节点
          let mynode = {};
          let keyArray = Object.keys(node);
          for (var item of keyArray) {
            mynode[item] = node[item]; //node对象的所有属性做成对象属性
          }
          if (children && children.length > 0) {
            mynode["children"] = this.formatTreeData(children); //进行递归调用
          } else {
            mynode["children"] = [];
          }

          result.push(mynode);
        }
      }
      return result;
    }
