JavaScript 递归的简单例子

function flattenTree(tree:any, result:any) {
  tree.forEach((node:any) => {
    result.push({ id: node.id, cat_name: node.cat_name, cat_name_en: node.cat_name_en });
    if (node.child.length > 0) {
      flattenTree(node.child, result);
    }
  });
}

let fdata1:any=ref([]);
flattenTree(res.data.data, fdata1.value);
