Instantiating a javascript object and populating its properties in a single line

Question

Is there a way I can do all of this in a constructor?

  obj = new Object();
  obj.city = \"A\";
  obj.town = \"B\";

Answer 1

function MyObject(params) {
    // Your constructor
    this.init(params);
}

MyObject.prototype = {
    init: function(params) {
        // Your code called by constructor
    }
}

var objectInstance = new MyObject(params);

This would be the prototype way, which i prefere over plain object literals when i need more then one instance of the object.

Answer 2

try this

var obj = {
    city : "A",
    town : "B"
};

Answer 3

try this:

function MyObject(city, town) {
  this.city = city;
  this.town = town;
}

MyObject.prototype.print = function() {
  alert(city + " " + town);
}

obj = new MyObject("myCity", "myTown");
obj.print();

Answer 4

Like so:

var obj = {
    city: "a",
    town: "b"
}

Answer 5

function cat(name) {
    this.name = name;
    this.talk = function() {
        alert( this.name + " say meeow!" )
    }
} 

cat1 = new cat("felix")
cat1.talk() //alerts "felix says meeow!"

Answer 6

You can write your custom constructor :

function myObject(c,t) {
    this.city = c;
    this.town = t;
}

var obj = new myObject("A","B");
