有没有办法将Ember Object转换为纯粹的JavaScript对象？ [英] Is there any way to convert Ember Object into plain javascript object?

问题描述

我找不到任何方式来完成这种转换的任务，因为我找不到任何获取对象的Ember.js属性的方法。 Ember.keys 仅返回在创建或 get 在 Ember.extend 中声明的属性不会显示在那里。我使用这样的属性来设置默认值（例如，数组属性的 [] ）

I could not find any way to accomplish the task of such conversion as I could not find any means of getting Ember.js properties for the object. Ember.keys returns only the properties I set in create or with get and the properties declared in Ember.extend do not show up there. I use such properties to set up default values (e.g. [] for array properties)

推荐答案

目前我用以下代码片段解决了这个问题：

At the moment I solve it with the following snippet:

App.plainCopy = function (obj) {
  if (Ember.isArray(obj)) {
    return obj.map(App.plainCopy);
  } else if (typeof(obj) === "object") {
    if (App.Plainable.detect(obj)) {
      return obj.plainCopy();
    } else {
      throw new Error(Ember.String.fmt("%@ is not Plainable", [obj]));
    }
  } else {
    return obj;
  }
}

App.Plainable = Ember.Mixin.create({
  plainCopy: function() {
    var props = Ember.keys(this);
    var proto = this.constructor.prototype;
    for(p in proto) {
      if (proto.hasOwnProperty(p) && typeof(this[p])!=="function") {
        props.push(p);
      }
    }
    var copy = {};
    props.forEach(function(p) {
      copy[p] = App.plainCopy(this.get(p));
    }, this);
    return copy;
  }
});

它不会上升类层次结构，不会调查mixins（因为我用于数据对象这是非常简单的形式）

It does not go up the class hierarchy and does not look into mixins (as I use for data objects which are quite simple form that point of view)
