工作示例

validate(a) {
    let newArr = [];
    for (const key in a) {
      if (key) {
        newArr.push({data: key, label: key, childern: this.validate(a[key])});
      }
    }
    return newArr;
}

const a = {
        "com": {
            "ups": {
                "demo": {
                    "a": 9
                }
            }
        }
    };

 console.log(this.validate(a));
