使对象变量在所有“更深”的范围内都是可访问的

Question

我目前正在用JS编写一种插件。我刚刚了解了对象，我对无法访问构造函数中设置的变量（两个或更多级别）这一事实感到恼火。我的意思是：

    var myConstructor = function()
    {
        this.one = "one";
        this.two = "two";
        this.publicMethod = function()
        {
          console.log("I can access: ", this.one);
          var privateMethod = function()
          {
              console.log("I cannot access var two like this: ", this.two);
          };
          privateMethod();
        };
    };
var myObject =  new myConstructor();
myObject.one = 1;
myObject.two = 2;
myObject.publicMethod();

那么，如何privateMethod访问构造函数中设置的变量呢？与 publicMethod 使用this相同的方式执行此操作。这可能吗？谢谢。

试试这个。

 var myConstructor = function()
        {
            this.one = "one";
            this.two = "two";
            this.publicMethod = function()
            {
                // new variable
                _two = this.two;
                console.log("I can access: ", this.one);
                var privateMethod = function()
                {
                    console.log("I cannot access var two like this: ", _two);
                };
                privateMethod();
            };
         };
