在JavaScript中将JSON数据转换为数组

Question

我的json数据是这样的:

[{"vehicleType":"car","make":"Dodge","model":"Durango","vin":"R90N8E95UB"},
{"vehicleType":"car","make":"Honda","model":"Accord","vin":"XJLSXU6NA5"},
{"vehicleType":"car","make":"Dodge","model":"Durango","vin":"2UNHFBCQG0"},
{"vehicleType":"car","make":"Volvo","model":"XC90","vin":"J37612ZVEC"},
{"vehicleType":"car","make":"Mercedes","model":"C250","vin":"J5QB24CFGS"},
{"vehicleType":"car","make":"Dodge","model":"Durango","vin":"OB60BC33LF"},
{"vehicleType":"car","make":"Volvo","model":"XC90","vin":"DCA3364SGK"},
{"vehicleType":"car","make":"Volvo","model":"XC60","vin":"FV2HML056G"},
{"vehicleType":"car","make":"BMW","model":"328xi","vin":"IGPP3DQ4SK"},
{"vehicleType":"car","make":"Mercedes","model":"C250","vin":"J5QB24CFGS"},
{"vehicleType":"car","make":"Honda","model":"Accord","vin":"XJLSXU6NA5"},
{"vehicleType":"car","make":"Mercedes","model":"C250","vin":"J5QB24CFGS"},
{"vehicleType":"car","make":"Dodge","model":"Durango","vin":"R90N8E95UB"}]

现在我希望我的数组在JavaScript中像这样:

// Javascript array
var array = [];
array[// vin number od above json array] = // the whole row of that vin number.

例如.,

// Javascript array
array["R90N8E95UB"][0] 
=[{"vehicleType":"car","make":"Dodge","model":"Durango","vin":"R90N8E95UB"}]
array["R90N8E95UB"][1] 
=[{"vehicleType":"car","make":"Dodge","model":"Durango","vin":"R90N8E95UB"}]

等等...

请提出建议.

谢谢.

Answer 1

您可以迭代并推送到内部数组.

var data = [{ vehicleType: "car", make: "Dodge", model: "Durango", vin: "R90N8E95UB" }, { vehicleType: "car", make: "Honda", model: "Accord", vin: "XJLSXU6NA5" }, { vehicleType: "car", make: "Dodge", model: "Durango", vin: "2UNHFBCQG0" }, { vehicleType: "car", make: "Volvo", model: "XC90", vin: "J37612ZVEC" }, { vehicleType: "car", make: "Mercedes", model: "C250", vin: "J5QB24CFGS" }, { vehicleType: "car", make: "Dodge", model: "Durango", vin: "OB60BC33LF" }, { vehicleType: "car", make: "Volvo", model: "XC90", vin: "DCA3364SGK" }, { vehicleType: "car", make: "Volvo", model: "XC60", vin: "FV2HML056G" }, { vehicleType: "car", make: "BMW", model: "328xi", vin: "IGPP3DQ4SK" }, { vehicleType: "car", make: "Mercedes", model: "C250", vin: "J5QB24CFGS" }, { vehicleType: "car", make: "Honda", model: "Accord", vin: "XJLSXU6NA5" }, { vehicleType: "car", make: "Mercedes", model: "C250", vin: "J5QB24CFGS" }, { vehicleType: "car", make: "Dodge", model: "Durango", vin: "R90N8E95UB" }],
    result = Object.create(null),
    keys;

data.forEach(function (a) {
    result[a.vin] = result[a.vin] || [];
    result[a.vin].push(a);
});

keys = Object.keys(result);

console.log(keys);
console.log(result);

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

var json = [{vehicleType:"car",make:"Dodge",model:"Durango",vin:"R90N8E95UB"},{vehicleType:"car",make:"Honda",model:"Accord",vin:"XJLSXU6NA5"},{vehicleType:"car",make:"Dodge",model:"Durango",vin:"2UNHFBCQG0"},{vehicleType:"car",make:"Volvo",model:"XC90",vin:"J37612ZVEC"},{vehicleType:"car",make:"Mercedes",model:"C250",vin:"J5QB24CFGS"},{vehicleType:"car",make:"Dodge",model:"Durango",vin:"OB60BC33LF"},{vehicleType:"car",make:"Volvo",model:"XC90",vin:"DCA3364SGK"},{vehicleType:"car",make:"Volvo",model:"XC60",vin:"FV2HML056G"},{vehicleType:"car",make:"BMW",model:"328xi",vin:"IGPP3DQ4SK"},{vehicleType:"car",make:"Mercedes",model:"C250",vin:"J5QB24CFGS"},{vehicleType:"car",make:"Honda",model:"Accord",vin:"XJLSXU6NA5"},{vehicleType:"car",make:"Mercedes",model:"C250",vin:"J5QB24CFGS"},{vehicleType:"car",make:"Dodge",model:"Durango",vin:"R90N8E95UB"}],
    result = [];
 
    json.forEach(v => result.push([v.vin, v]));
    console.log(result);
