获取数组中父级及其子级的所有材料(少数除外

// 假设我们有以下数据结构
const materials = [
  { id: 1, name: 'Material A', parentId: null },
  { id: 2, name: 'Material B', parentId: 1 },
  { id: 3, name: 'Material C', parentId: 1 },
  { id: 4, name: 'Material D', parentId: 2 },
  { id: 5, name: 'Material E', parentId: 2 },
  { id: 6, name: 'Material F', parentId: 3 },
  // ... 其他材料
];

// 少数需要排除的材料ID列表
const excludeIds = [4, 6];

// 递归函数，用于获取父级及其子级的所有材料
function getMaterialsWithChildren(materials, excludeIds, parentId = null) {
  return materials
    .filter(material => material.parentId === parentId && !excludeIds.includes(material.id))
    .map(material => ({
      ...material,
      children: getMaterialsWithChildren(materials, excludeIds, material.id)
    }));
}

// 调用函数并打印结果
const result = getMaterialsWithChildren(materials, excludeIds);
console.log(JSON.stringify(result, null, 2));
