递归数据格式转换
现有这么一种格式的数据如下：
[{ "id": 1, "name": "baidvbusbdviyw", "parentId": 0, "memo": "", "parentsFeature": ",", "empId": 3, "createTime": 1503628821000, "updateTime": 1503628821000}, { "id": 10, "name": "啦", "parentId": 0, "memo": "", "parentsFeature": ",", "empId": 3, "createTime": 1503889222000, "updateTime": 1503889222000}, { "id": 19, "name": "123123", "parentId": 0, "memo": "", "parentsFeature": ",", "empId": 3, "createTime": 1503905894000, "updateTime": 1503905894000}, { "id": 20, "name": "edwsxd", "parentId": 19, "memo": "", "parentsFeature": ",19,", "empId": 3, "createTime": 1503905923000, "updateTime": 1503905923000}, { "id": 21, "name": "cdacevdvcdsc", "parentId": 20, "memo": "", "parentsFeature": ",19,20,", "empId": 3, "createTime": 1503905953000, "updateTime": 1503905953000}, { "id": 23, "name": "啦的儿子", "parentId": 10, "memo": "", "parentsFeature": ",10,", "empId": 3, "createTime": 1503907240000, "updateTime": 1503907240000}, { "id": 24, "name": "陈蛐蛐赌场全额v", "parentId": 0, "memo": "", "parentsFeature": ",", "empId": 3, "createTime": 1503907568000, "updateTime": 1503907568000}, { "id": 25, "name": "qecvq", "parentId": 24, "memo": "", "parentsFeature": ",24,", "empId": 3, "createTime": 1503907577000, "updateTime": 1503907577000}, { "id": 26, "name": "4个4个 ", "parentId": 24, "memo": "", "parentsFeature": ",24,", "empId": 3, "createTime": 1503911753000, "updateTime": 1503911753000}, { "id": 27, "name": "啦的孙子", "parentId": 23, "memo": "", "parentsFeature": ",10,23,", "empId": 3, "createTime": 1503915740000, "updateTime": 1503915740000}, { "id": 28, "name": "啦的二儿子", "parentId": 10, "memo": "", "parentsFeature": ",10,", "empId": 3, "createTime": 1503915761000, "updateTime": 1503915761000}, { "id": 29, "name": "啦的曾孙子", "parentId": 27, "memo": null, "parentsFeature": ",10,23,27,", "empId": 3, "createTime": 1503915781000, "updateTime": 1503972701000}, { "id": 31, "name": "确认v请问v", "parentId": 30, "memo": "", "parentsFeature": ",30,", "empId": 3, "createTime": 1503974430000, "updateTime": 1503974430000}, {"id": "asdvasdva", "name": "啦啦啦啦", "parentId": 0}, { "id": "vasdvwrvwdqvw", "name": "啦啦啦陈摩的常年卧", "parentId": "asdvasdva"}];想将其转化成为这样的
