How to add data to javascript object at run time

I tried to add data to js object at run time this way but getting error. Tell me where I made the mistake?

This line giving the problem

Persons.push(new Person(id:id,name:name,salary:sal));

Here is my code:

$(document).ready(function () {
$("#btnSave").click(function () {
var id,name,salary;
Persons.push(new Person(id:id,name:name,salary:sal));
return false;

$("#btnDelete").click(function () {
return false;

var Persons = [];
var Person = function (id, name, salary) { = id; = name;
this.salary = salary;

You do not need to pass the parameter/argument names. Just pass the values to your Person constructor.

id = $("#txtID").val();
name = $("#txtName").val();
sal = $("#txtSal").val();
Persons.push(new Person(id,name,sal));
