实例化javascript对象并在一行中填充其属性

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。

Answer 4

试试这个

 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

您可以编写自定义构造函数：

 function myObject(c,t) { this.city = c; this.town = t; } var obj = new myObject("A","B"); 

Answer 7

试试这个：

 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 8

不要让事情复杂化。 这是定义构造函数的最简单方法。

 var Cont = function(city, town) { this.city = city; this.town = town; } var Obj = new Cont('A', 'B');
