更新 如何在ViewportSizeMonitor处理程序中访问this.darklayer ???

goog.require('goog.events');
goog.require('goog.events.EventType');
goog.require('goog.math.Size');
goog.require('goog.style');

goog.require('goog.dom.ViewportSizeMonitor');

goog.provide('ehsun7b.ajax.AjaxBox');

ehsun7b.ajax.AjaxBox = function (url, containerClass) {
  try {
    this.url = url;
    this.containerClass = containerClass;

    var viwportSize = goog.dom.getViewportSize();
    this.darklayer = goog.dom.createDom("div", {
      "style": "width: " + viwportSize.width + "px;" + "height: " + 
      viwportSize.height + "px;" +
      "background-image: url('css/img/50black.png');" +
      "z-index: 1000;" +
      "position: absolute;" +
