JavaScript : How to get reference to the parent object inside a child object

Question

我有以下代码，其中我无法获取对 OnKeyUp 函数内父对象的引用。据我所知，在 OnKeyUp 方法中，“this”指的是文本框。但是我如何访问父对象以便 var textboxID 获得正确的值？

       function $MyObject() {

        this.Control = {

            inputBox: "#inputBox1",

            name: "Control1",

            BindEvent: function () {
                $(this.inputBox).keyup(this.OnKeyUp);
            },


            OnKeyUp: function () {
                var textBoxID = this.inputBox;
                alert(textBoxID);
            }


        }
    }


    $(document).ready(function () {

        var object1 = new $MyObject();
        object1.Control.BindEvent();

    });

function $MyObject() {
    var self = this.Control = {

        inputBox: "#inputBox1",

        name: "Control1",

        BindEvent: function () {
            $(self.inputBox).keyup(self.OnKeyUp);
        },


        OnKeyUp: function () {
            var textBoxID = self.inputBox;
            alert(textBoxID);
        }


    };
}
