问题描述

吸烟者和二传手是VB.Net的美女:

Getters and setters are a beauty in VB.Net:

Get
    Return width
End Get
Set(ByVal value As Integer)
    width = value
End Set

在Javascript中,这可能是我们要做的:

In Javascript, this is probably what we would do:

function Test() {
    var width = 100;
    this.__defineGetter__("Width", function() {
        return width;
    });
    this.__defineSetter__("Width", function(value){
        width = value;
    });
}

看起来像是一盘被kuri洗过的意大利面。我们有哪些更简洁的选择?

It looks like a plate of spaghetti ransacked by a kuri. What are some neater alternatives we have?

推荐答案

使用ES5,您将能够:

With ES5 you'll be able to do:

function Test() {
  var a = 1;

  return {
    get A() { return a; },
    set A(v) { a = v; }
  };
}

getter / setter函数当然可以做任何你想要的事情。

The getter/setter functions can of course do anything you want them to.
