无法读取未定义的属性... addEventListener回调函数名称作为字符串文字在变量中

Question

为了动态代码，我需要ObjectOne.featureChanged的addEventListener回调函数作为ObjectTwo中特定于功能的函数。将EventListener中的回调函数设置为其他对象中的函数可以正常工作。当我有一个字符串，该字符串具有需要连接的功能名称时＃39;到回调函数＆＃39;继承路径。＆＃39;我的搜索范围很广，但窗口和评估对我来说都不适合。预先连接整个路径也不起作用。

window.onload = function() {
  ObjectOneInstance.startup();
}
ObjectOne = {
  startup: function() {
    this.featureChanged.currFeature = null;
    document.getElementById("FeatureOne").addEventListener("click", ObjectTwo.FeatureOne, false);
  },
  featureChanged: function(newFeature) {
    var self = this.featureChanged;
    if (self.currFeature == null) {
      self.currFeature = newFeature;
      //*****Below is where the problem resides*****//
      document.getElementById(self.currFeature).removeEventListener("click", ObjectTwo.window[self.currFeature], false);
    } else {
      document.getElementById(self.currFeature).addEventListener("click", ObjectTwo.window[self.currFeature], false);
      document.getElementById(newFeature).removeEventListener("click", ObjectTwo.window[newFeature], false);
      self.currFeature = newFeature;
    }
  }
}
ObjectTwo = {
  FeatureOne: function() {
    FeaturesSupportModuleInstance.featureChanged("financial");
    //feature functionality Here
  }
}
var ObjectOneInstance = Object.create(ObjectOne);
var ObjectTwoInstance = Object.create(ObjectTwo);
