树形转换

扁平化

// 树形扁平化
export const treeDataToPlanishData = (list, parent, level = 0, clues = []) => { // eslint-disable-line
  return list.reduce((prev, {
    children = [],
    ...rest
  }) => {
    const parentKey = parent || '';
    const keyClues = clues.concat(rest.key);
    return prev.concat({ ...rest,
      parentKey,
      level,
      isLeaf: !!parentKey,
      keyClues,
    }, treeDataToPlanishData(children, rest.key, level + 1, keyClues));
  }, []);
};

转树形

export const planishDataToTreeData = (data) => {
    const idMap = {};
    const jsonTree = [];
    data.forEach((v) => {
      idMap[v.key] = v;
    });
    data.forEach((v) => {
      const parent = idMap[v.parentKey];
      if (parent) {
        parent.children = parent.children || [];
        parent.children.push(v);
      } else {
        jsonTree.push(v);
      }
    });
  return jsonTree;
};
