My object

var person = [{ FIrstName: "", LastName: "", MiddleName: "" }];

My data

var names = [
 "Steve", "Mark", "John", // person 1
 "James", "Andrew", "wells", // person 2
 "Clarke", "Finche", "Gomes" // person 3
];

So I want to push the names array in person object.

$(names).each(function (index, item) {
 //Here I need to push the values
});

As you can see I don't have separate arrays for last names and middle names.

I want my output as :

[
 { "FIrstName": "Steve", "LastName": "Mark", "MiddleName": "John" },
 { "FIrstName": "James", "LastName": "Andrew", "MiddleName": "wells" },
 { "FIrstName": "Clarke", "LastName": "Finche", "MiddleName": "Gomes" }
]

Please assist me.

GG.

    It's not clear what the array should look like after processing Commented Apr 17, 2016 at 15:42
  • Suggest you fix the source of names array. Where does it come from? Commented Apr 17, 2016 at 15:56

Here is what you want to achieve.

var names = ["Steve","Mark","John","James","Andrew", "wells","Clarke","Finche","Gomes"];
var person = [];
for(var i=0; i<names.length; i+=3) {
 person.push({
 	FIrstName: names[i],
 	LastName: names[i+1],
 	MiddleName: names[i+2]
 });
}
document.write(JSON.stringify(person));

Also you can firstly split you array to array of chunks..

var names = ["Steve","Mark","John","James","Andrew", "wells","Clarke","Finche","Gomes"];
var chunks = [];
while(names.length) {
	chunks.push(names.splice(0, 3));
}
var result = chunks.map(function(person) {
	return {
 	FIrstName: person[0],
 	LastName: person[1],
 	MiddleName: person[2]
 }
});
document.write(JSON.stringify(result));

Thanks alot. But I want Last Name and Middle Name as well.
Do you have separate arrays with last names and middle names?
No, thats my problem.
@Pearl then you haven't provided a proper problem description in the question. We can't guess what you need or what you have

Use for loop with increment i by 3

var names = ["Steve", "Mark", "John", "James", "Andrew", "wells", "Clarke", "Finche", "Gomes"];
var person = [];
for (var i = 0; i < names.length; i += 3) {
 person.push({
 FIrstName: names[i],
 LastName: names[i + 1],
 MiddleName: names[i + 2]
 });
}

Could be off-topic, but if you consider using Lodash:

_.map(_.chunk(names, 3), function (person) {
 return _.zipObject(['FirstName', 'LastName', 'MiddleName'], person);
});

This is a small proposal with Array#reduce(). 

var keys = ['FirstName', 'LastName', 'MiddleName'],
 names = ["Steve", "Mark", "John", "James", "Andrew", "wells", "Clarke", "Finche", "Gomes"],
 persons = names.reduce(function (r, a, i) {
 var index = Math.floor(i / 3);
 r[index] = r[index] || {};
 r[index][keys[i % 3]] = a;
 return r;
 }, []);
document.write('<pre>' + JSON.stringify(persons, 0, 4) + '</pre>');
