在JavaScript中將JSON數據轉換為數組

Question

我的json數據是這樣的：

[{"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"}]

現在我希望我的數組在JavaScript中像這樣：

// 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...

請提出建議。

謝謝。

Answer 1

您可以迭代並推送到內部數組。

 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);

 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); 

Answer 3

在ES2015中：var arr = Object.values（obj）;

Answer 4

希望這可以幫助 ：

 var arr = {}; var pop = [{"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"}]; pop.forEach(function(item){ if ( arr[item.vin] ) { arr[item.vin].push([item]); } else { arr[item.vin] = [[item]]; } }); console.log(JSON.stringify(arr["R90N8E95UB"][0])); console.log(JSON.stringify(arr["R90N8E95UB"][1])); console.log(JSON.stringify(arr)); 

Answer 5

您可以使用Array.reduce

 var yourData = [{"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"}]; var result = yourData.reduce(function (acc,curr) { acc[curr.vin]= acc[curr.vin] || []; acc[curr.vin].push(curr); return acc; },{}); console.log(result); 

Answer 6

嘗試這個

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"}];



        var array = [];
        for(var k= 0 ,l = data.length;k<l;k++){
            array[data[k].vin] = data[k];       
        }
        console.log(array);

Answer 7

你為什么不簡單地把它分配給某事？

var array =    [{"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"}]

然后

array[0]:
Object {vehicleType: "car", make: "Dodge", model: "Durango", vin: "R90N8E95UB"}

但是如果你需要根據他們的vin查找汽車，那么將vin作為密鑰，變量需要是一個對象，而不是一個數組。

var object = {"R90N8E95UB": {"vehicleType": "car", make: "Dodge", model: "Durango"},
              "J5QB24CFGS": {"vehicleType":"car","make":"Mercedes","model":"C250"}}

Answer 8

如果你有一個對象的顯示方式，你可以通過Object.values（）得到一個數組

Answer 9

您的JSON數據已經是一個數組。 獲取數據的一種方法可以通過值或屬性從對象數組中獲取JavaScript對象在那里，您可以找到查詢JSON數組的方法。
