数据量少的话,for就好了,要是有多级结构,最好用数组的形式(JSON多几层没关系,关键是结构清晰,方便扩展):
{
[
{"main_1":{"data":{"cid" : "1","name" : "品牌1","pid" : "0"},"Sub":"[
{"main_1":{"data":{"cid" : "1","name" : "品牌1","pid" : "0"}}},
...
]"}},
{"main_2":{"data":{"cid" : "1","name" : "品牌1","pid" : "0"},"Sub":"[...]"}},
...
]
}
{
[
{"main_1":{"data":{"cid" : "1","name" : "品牌1","pid" : "0"},"Sub":"[
{"main_1":{"data":{"cid" : "1","name" : "品牌1","pid" : "0"}}},
...
]"}},
{"main_2":{"data":{"cid" : "1","name" : "品牌1","pid" : "0"},"Sub":"[...]"}},
...
]
}
