};上面當我選取:
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对应的价格第二種:

"buyer":"33.00",
"attribute":"0"
}
]
}預設
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
這兩種json資料格式那種更為簡潔，效率更有效率?
有資料冗餘重複的時候，盡量消除資料的重複。上面的兩種資料組織方式都沒有冗餘，但是為了查詢方便，資料格式的組織可以像資料庫一樣，有一個方便查詢的主鍵，也可以說是id。所以個人覺得上面的那種方式好一點，可以直接用key查到value。而下面的那種方式感覺查詢起來有些麻煩。
資料格式的組織也盡量範式化：
上面的引述是來自Redux官方文件推薦的state組織方式，可以參考一下。
