My json data is like that:
[{"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"}]
Now I want my array to be like this in JavaScript:
// Javascript array
var array = [];
array[// vin number od above json array] = // the whole row of that vin number.
For example.,
// Javascript array
array["R90N8E95UB"][0]
=[{"vehicleType":"car","make":"Dodge","model":"Durango","vin":"R90N8E95UB"}]
array["R90N8E95UB"][1]
=[{"vehicleType":"car","make":"Dodge","model":"Durango","vin":"R90N8E95UB"}]
And so on...
Please advice on it.
Thank you.

Reset to default 8You could iterate and push to the inner array.
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);In ES2015: var arr = Object.values(obj);
Hope 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));You can use Array.reduce
var yourData = [{"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);try this
var data = [{"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);
Why don't you simply assign it to something?
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"}]
Then
array[0]:
Object {vehicleType: "car", make: "Dodge", model: "Durango", vin: "R90N8E95UB"}
But if you need to lookup a car based on their vin, make the vin the key and the variable needs to be an object, not an array.
var object = {"R90N8E95UB": {"vehicleType": "car", make: "Dodge", model: "Durango"},
"J5QB24CFGS": {"vehicleType":"car","make":"Mercedes","model":"C250"}}
If you have an object the way you showed, you can get an array by Object.values()
Your JSON data IS already an array. One way to get the data can be found at Get JavaScript object from array of objects by value or property There you can found a way to query your JSON Array.
