Convert JSON-Daten zu Array in JavaScript

Question

Meine json Daten ist wie folgt aus:

[{"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"}] 

Jetzt möchte ich meine Array wie folgt in JavaScript sein.

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

Zum Beispiel

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

Und so weiter ...

Bitte a Dvice darauf.

Vielen Dank.

Answer 1

Sie können an der inneren Arrays durchlaufen und drücken.

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; }

Answer 2

In ES2015: var arr = Objektwerte (obj);

Answer 3

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 4

können Sie verwenden 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 5

versuchen, diese

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 6

Warum ordnen Sie es nicht einfach etwas zu?

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"}] 

Dann

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

Aber wenn man braucht ein Auto zum Nachschlagen auf der Grundlage ihrer vin, macht die vin den Schlüssel und die Variable muss ein Objekt sein, nicht ein Array.

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

Answer 7

this helps:

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 8

Wenn Sie ein Objekt den Weg haben Sie gezeigt, ein Array von Object.values ​​bekommen kann()

Answer 9

Ihre JSON-Daten sind bereits ein Array. Eine Möglichkeit, die Daten zu erhalten, finden Sie unter Get JavaScript object from array of objects by value or property Dort können Sie eine Möglichkeit finden, Ihre JSON-Array abzufragen.
