javascript - 从数组创建动态对象树

Question

我有这些数组

countryList = ["United Kingdom", "France", "Tajikstan"]

countryDetails = ["Markets", "Government", "Details"] 

countryFactors = ["Capital", "Labour", "Land"]

marketList = ["Primary", "Secondary", "Service"]

businessList = ["Businesses", "Info"]

supplyAndDemand = ["Supply", "Demand", "Price"]

我想让这些数组组成一个对象如下

Country.list ={
"United Kingdom":{
    "Markets":{ 
        "Primary":{
            "Businesses":{},
            "Info":{
                "Suppy":0,
                "Demand":0,
                "Price":0,
            },
        },
        "Secondary":{
            "Businesses":{},
            "Info":{
                "Suppy":0,
                "Demand":0,
                "Price":0,
            },
        },
        "Service":{
            "Businesses":{},
            "Info":{
                "Suppy":0,
                "Demand":0,
                "Price":0,
            },
        },
    },
    "Government":{

    },
    "Details":{
        "Capital":{
            "Info":{
                "Suppy":0,
                "Demand":0,
                "Price":0,
            },
        },
        "Labour":{
            "Info":{
                "Suppy":0,
                "Demand":0,
                "Price":0,
            },
        },
        "Land":{
            "Info":{
                "Suppy":0,
                "Demand":0,
                "Price":0,
            },
        },
    },  
},

"France":{
    "Markets":{ 
        "Primary":{
            "Businesses":{},
            "Info":{
                "Suppy":0,
                "Demand":0,
                "Price":0,
            },
        },
        "Secondary":{
            "Businesses":{},
            "Info":{
                "Suppy":0,
                "Demand":0,
                "Price":0,
            },
        },
        "Service":{
            "Businesses":{},
            "Info":{
                "Suppy":0,
                "Demand":0,
                "Price":0,
            },
        },
    },
    "Government":{

    },
    "Details":{
        "Capital":{
            "Info":{
                "Suppy":0,
                "Demand":0,
                "Price":0,
            },
        },
        "Labour":{
            "Info":{
                "Suppy":0,
                "Demand":0,
                "Price":0,
            },
        },
        "Land":{
            "Info":{
                "Suppy":0,
                "Demand":0,
                "Price":0,
            },
        },
    },  
  },
}

所以基本上取决于数组的名称，指示后面的内容。因此，如果数组名称是“Markets”，那么该数组下面将是“marketList”数组。等等

有人有想法吗？我想在循环后做一个 if 语句，但 if 语句一直在修改我的代码。

您可以对任何深度的嵌套对象使用动态方法。

function iter(object, i) {
    data[i].forEach(function (k) {
        if (i + 1 < data.length) {
            object[k] = {};
            iter(object[k], i + 1);
        } else {
            object[k] = 0;
        }
    });
}

var data = [["United Kingdom", "France", "Tajikstan"], ["Markets", "Government", "Details"], ["Capital", "Labour", "Land"], ["Primary", "Secondary", "Service"], ["Businesses", "Info"], ["Supply", "Demand", "Price"]],
    tree = {};

iter(tree, 0);
console.log(tree);

.as-console-wrapper { max-height: 100% !important; top: 0; }
