将json数据转换为带有方法的对象的最简单方法? [英] Easiest way to convert json data into objects with methods attached?

问题描述

将包含对象数据的json转换为带有方法的实际对象的最快，最简单的方法是什么?

通过示例的方式，我获得了一个果钵的数据，该果钵具有一系列水果对象，这些水果对象进而包含一系列种子:

By way of example, I get data for a fruitbowl with an array of fruit objects which in turn contain an array of seeds thus:

{"fruitbowl": [{
     "name": "apple", 
     "color": "red", 
     "seeds": []
   },{
     "name": "orange", 
     "color": "orange", 
     "seeds": [
        {"size":"small","density":"hard"},
        {"size":"small","density":"soft"}
    ]}
}

这一切都很好，但是在客户身上，我们用这种水果做东西，比如吃它并种下树木...

That's all nice and good but down on the client we do stuff with this fruit, like eat it and plant trees...

 var fruitbowl = []
 function Fruit(name, color, seeds){
     this.name = name
     this.color = color
     this.seeds = seeds
     this.eat = function(){
         // munch munch
     }
 }
 function Seed(size, density){
     this.size = size
     this.density = density
     this.plant = function(){
          // grow grow
     }
 }

我的ajax的成功例程当前正在遍历该事物并依次构造每个对象，并且它还不能处理种子，因为在我遍历遍历种子构造函数之前，我正在思考

My ajax's success routine currently is currently looping over the thing and constructing each object in turn and it doesn't handle the seeds yet, because before I go looping over seed constructors I'm thinking

有没有更好的方法?

    success: function(data){           
        fruitbowl.length = 0
        $.each(data.fruitbowl, function(i, f){
            fruitbowl.push(new Fruit(f.name, f.color, f.seeds))
        })

我还没有探索过按原样循环对象并附加所有方法的问题.那行得通吗?

I haven't explored looping over the objects as they are and attaching all the methods. Would that work?

推荐答案

将数据传递给对象构造函数，然后使用jquery的"extend"组合数据和方法:

Pass the data to the object constructor then use jquery's "extend" to combine the data and methods:

 function Fruit(data){
     $.extend(this, data)
     this.eat = function(){
         // munch munch
     }
 }
 ...
       $.each(data.fruitbowl, function(i, f){
           fruitbowl.push(new Fruit(f))
       })

您仍然涉及到循环；并且必须手动为嵌套对象(例如种子)编写循环代码，但这仍然是解决问题的一种非常简单的方法.

You still have loops involved; and must manually code loops for the nested objects (like seeds), but still a very simple way to get past the problem.
