使用常规的方法传值

// recursion .js 转换树
const recursion = {
  // 转换树结构并将需要的值存进树中
  // 存值为：除了树结构必须的值外，我需要发送给后台的值 (code)
  convertTree: function (tree, map) {
    const result = [];
    tree.forEach((item) => {
      // 读取 map 的键值映射
      let expand = !!item.children;
      let checked = false;
      let title = item[ map.title ];
      let code = item[ map.code ];
      let children = item[ map.children ];
      // 如果有子节点，递归
      if (children) {
        children = this.convertTree(children, map);
      }
      result.push({ expand, checked, code, title, children });
    })
    return result;
  },
}

export default recursion

// vue文件中引入
import recursion  from './recursion '

// 后台返回的字段
