实例化javascript对象并在一行中填充其属性

Question

有没有办法在构造函数中完成所有这些操作？

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

Answer 1

你为什么不这样做:

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

Answer 2

像这样:

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

Answer 3

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

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

var objectInstance = new MyObject(params);

这将是原型方式,当我需要多于一个对象的实例时,我优先于普通对象文字.
