};上面当我选中:
颜色的data-aid为3，规格的data-aid为13时，默认价格更新为3_13对应的价格
data-aid为3， 规格的data-aid为14时，默认价格更新为3_14对应的价格
data-aid为4， 规格的data-aid为13时，默认更新为4_13对应的价格第二种:
{
"library":[
{
"product_color":"625",
"product_spec":"626",
"buyer":"46.15",
"attribute":"0"
},
{
"product_color":"625",
"product_spec":"627",
"buyer":"46.15",
"attribute":"0"
},
{
"product_color":"625",
"product_spec":"628",
"buyer":"50.00",
"attribute":"1"
},{
"product_color":"629",
"product_spec":"627",
"buyer":"33.00",
"attribute":"0"
}
]
}默认
颜色product_color: 625
规格product_spec: 627
价格为46.15
当选择product_color: 625, 规格为628，对应价格为50.00
当选择product_color: 629, 规格为627,对应的价格为33.00
这两种json数据格式那种更为简洁，效率更高效?

有数据冗余重复的时候，尽量消除数据的重复。上面的两种数据组织方式都没有冗余，但是为了查询方便，数据格式的组织可以像数据库一样，有一个便于查询的主键，也可以说是id。所以个人感觉上面的那种方式好一点，可以直接通过key查到value。而下面的那种方式感觉查询起来有些麻烦。
数据格式的组织也尽量范式化：
上面的引用是来自Redux官方文档推荐的state组织方式，可以参考一下。
