内部javascript清除功能

Question

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

例如，

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

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

我试过

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

和

function(){
  currentStrategy = {};
}

但都不起作用。

Answer 1

使用以下内容。实例属性需要this。

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

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