电商Sku排列

使用了Array.reduce方法实现
/* 参数 source 格式 { 商品规格1:['规格值1','规格值2'],商品规格2:['规格值3','规格值4'] ... } /
/ 返回值 newArr 格式[[{商品规格1:规格值1},{商品规格2:规格值3}],[{商品规格1:规格值1},{商品规格2:规格值4}],[{商品规格1:规格值2},{商品规格2:规格值3}],[{商品规格1:规格值2},{商品规格2:规格值4}]]*/
const GetSkuList = (sources) => {
console.log(sources);
let skuList = Object.values(sources);
let columns = Object.keys(sources);
let newArr = skuList.reduce(
(a, b, index) => {
var ret = [];
if (b.length != 0) {
a.forEach(function (a) {
b.forEach(function (b) {
ret.push(a.concat({ [columns[a.length]]: b }));
});
});
return ret;
} else {
return a;
}
},
[[]],
);
return newArr;
};
