Question

我正在努力订购JavaScript对象。这是我要排序的数据部分。

我想按ParentMemberCode对每个对象进行分组，然后按Order排序。

{
    "MemberCode": "B1G",
    "ParentMemberCode": "B1_GA",
    "MemberName": "Gross value added at basic prices, total activity",
    "Order": 1
},
{
    "MemberCode": "P119",
    "ParentMemberCode": "B1_GA",
    "MemberName": "Financial Intermediation Services Indirectly Measured (FISIM)",
    "Order": 2
},
{
    "MemberCode": "B1G_P119",
    "ParentMemberCode": "B1_GA",
    "MemberName": "Gross value added at basic prices, excluding FISIM",
    "Order": 3
},
{
    "MemberCode": "D21_D31",
    "ParentMemberCode": "B1_GA",
    "MemberName": "Taxes less subsidies on products",
    "Order": 4
},
{
    "MemberCode": "B1_GE",
    "ParentMemberCode": "GDP",
    "MemberName": "Gross domestic product - expenditure approach",
    "Order": 1
},
{
    "MemberCode": "GDP",
    "ParentMemberCode": "GDP",
    "MemberName": "Gross domestic product",
    "Order": 1
},
{
    "MemberCode": "B1_GI",
    "ParentMemberCode": "GDP",
    "MemberName": "Gross domestic product - income approach",
    "Order": 2
},
{
    "MemberCode": "B1_GA",
    "ParentMemberCode": "GDP",
    "MemberName": "Gross domestic product at market prices - output approach",
    "Order": 3
}

我想重组和排序这样的数据：

{
    "MemberCode": "GDP",
    "ParentMemberCode": "GDP",
    "MemberName": "Gross domestic product",
    "Order": 1
}

{
    "MemberCode": "B1_GE",
    "ParentMemberCode": "GDP",
    "MemberName": "Gross domestic product - expenditure approach",
    "Order": 1
},
,
{
    "MemberCode": "B1_GI",
    "ParentMemberCode": "GDP",
    "MemberName": "Gross domestic product - income approach",
    "Order": 2
},
{
    "MemberCode": "B1_GA",
    "ParentMemberCode": "GDP",
    "MemberName": "Gross domestic product at market prices - output approach",
    "Order": 3,
    [
        {
            "MemberCode": "B1G",
            "ParentMemberCode": "B1_GA",
            "MemberName": "Gross value added at basic prices, total activity",
            "Order": 1
        },
        {
            "MemberCode": "P119",
            "ParentMemberCode": "B1_GA",
            "MemberName": "Financial Intermediation Services Indirectly Measured (FISIM)",
            "Order": 2
        },
        {
            "MemberCode": "B1G_P119",
            "ParentMemberCode": "B1_GA",
            "MemberName": "Gross value added at basic prices, excluding FISIM",
            "Order": 3
        },
        {
            "MemberCode": "D21_D31",
            "ParentMemberCode": "B1_GA",
            "MemberName": "Taxes less subsidies on products",
            "Order": 4
        },
    ]
}

这对我来说非常复杂，所以我需要你的帮助。你有什么想法吗？

请不要限制你的想法w / underscore.js。

Answer 1

我最近必须做类似的事情，我使用了Underscore.nest（https://github.com/iros/underscore.nest），这是一个简洁的小js插件，你可以指定一个字段来折叠数据，然后你可以使用underscore.sort对生成的树结构进行排序？

我正要说我不知道这里有什么大问题。但后来我意识到你想要的是无效的。

如果没有密钥，则无法在对象中拥有项目。

{
    "MemberCode": "B1_GA",
    "ParentMemberCode": "GDP",
    "MemberName": "Gross domestic product at market prices - output approach",
    "Order": 3,
    [
        {
            "MemberCode": "B1G",
            "ParentMemberCode": "B1_GA",
            "MemberName": "Gross value added at basic prices, total activity",
            "Order": 1
        },
....

不会创建有效对象。你需要一个持有数组的属性的名称。

{
    "MemberCode": "B1_GA",
    "ParentMemberCode": "GDP",
    "MemberName": "Gross domestic product at market prices - output approach",
    "Order": 3,
    "Children": [
        {
            "MemberCode": "B1G",
            "ParentMemberCode": "B1_GA",
            "MemberName": "Gross value added at basic prices, total activity",
            "Order": 1
        },
....

就创建它而言，您只需要能够遍历最顶层数组中的对象，通过它ParentMemberCode查找每个MemberCode（您可能想要创建另一个字典，指向在迭代之前，每个对象由MemberCode直接进行，以便每次查找取平均日志（项目数）），并将子项添加到父项Children数组中（当您添加数组时）取决于你），然后，也许在你搜索或之后，过滤掉所有已经分配了父母的对象（不是他们自己）。
