如何根据对象值在 JavaScript 中实现组合？

Question

我正在尝试编写一个函数来给出这样的数据数组的排列：

 var selectedData={
        selectedAccount:"a1,a2",
        selectedYear:"2019,2018",
        selectedProduct:"p1,p2",

    }

我想要这样的结果：

[
    {
        selectedAccount: "a1",
        selectedYear: "2018",
        selectedProduct: "p1",
    },
    {
        selectedAccount: "a1",
        selectedYear: "2018",
        selectedProduct: "p2",
    },
    {
        selectedAccount: "a1",
        selectedYear: "2019",
        selectedProduct: "p1",
    },
    {
        selectedAccount: "a1",
        selectedYear: "2019",
        selectedProduct: "p2",
    },
    {
        selectedAccount: "a2",
        selectedYear: "2018",
        selectedProduct: "p1",
    },
    {
        selectedAccount: "a2",
        selectedYear: "2018",
        selectedProduct: "p2",
    },
    {
        selectedAccount: "a2",
        selectedYear: "2019",
        selectedProduct: "p1",
    },
    {
        selectedAccount: "a2",
        selectedYear: "2019",
        selectedProduct: "p2",
    },
]

我一直在努力使用某种类型的递归函数，但没有运气！ 任何人都可以提出想法来实现上述结果

只需创建嵌套的for循环，如下所示：

 let selectedData = { selectedAccount: "a1,a2", selectedYear: "2019,2018", selectedProduct: "p1,p2", }; let result = []; for (let selectedAccount of selectedData.selectedAccount.split(",")) { for (let selectedYear of selectedData.selectedYear.split(",")) { for (let selectedProduct of selectedData.selectedProduct.split(",")) { result.push({ selectedAccount, selectedYear, selectedProduct }); } } } console.log(result);
