内部javascript清除函数

我有两个用于复制数据对象的javascript对象。它们是通过onclick事件填写的，我想在保存事件后清除它们

比如说,

var currentStrategy = {
  id : "",
  label : "",
  dueDate : "",
  comments = [],

  save : saveStrategyHandler,
  clear : function() {
    //how do I clear the fields above in here?
  }
}

我试过了

function(){
  id = "";
  label = "";
  dueDate = "";
  comments = [];
}

及

---

但这两种方法都不起作用。

使用以下方法。实例属性需要一个

this

var currentStrategy = {
  id : "",
  label : "",
  dueDate : "",
  comments = [],

  save : saveStrategyHandler,
  clear : function() {
    this.id = "";
    this.label = "";
    this.dueDate = "";
    this.comments = [];
  }
}

指定给对象的属性，而不是某些变量。

var currentStrategy = {
  id : "",
  label : "",
  dueDate : "",
  comments = [],

  save : saveStrategyHandler,
  clear : function() {
    this.id = "";
    this.label = "";
    this.dueDate = "";
    this.comments = [];
  }
}
