javascript - JS 对象文字 - 如何从对象外部访问？

Question

我是 JavaScript 的新手，在从外部访问对象时遇到了麻烦。在我想访问此对象的属性之前，我的方法用对象填充数组。

Reservation = {
   objArr: [],                     // stores CalendarDates objects
   dates: ["test", "foo", "bar"],  // some test strings

   actionMethod: function() {
      Reservation.objArr[0] = new Reservation.CalendarDate.construct(Reservation.dates[0]);
      alert(Reservation.dates[0].testVariable);        // returns 'undefined'
   }
};

Reservation.CalendarDate = {
   testVariable: '',
   construct: function(testVariable) {
      Reservation.CalendarDate.testVariable = testVariable;
   }
};

如何从存储在数组中的对象外部访问属性 (testVariable)。

感谢您的帮助!

我认为您正在尝试按照这些思路完成某些事情...

    var Reservation = {
       objArr: [],                     // stores CalendarDates objects
       dates: ["test", "foo", "bar"],  // some test strings

       actionMethod: function() {
         var temp = new Reservation.CalendarDate(Reservation.dates[0]);
          Reservation.objArr[0] = temp;
          alert(Reservation.objArr[0].testVariable);
       }
      };

      Reservation.CalendarDate = function(testVariable) {
         this.testVariable = testVariable;
      };

      Reservation.actionMethod();
