jQuery 解析 JSON 对象和数组

Question

在下面的代码中:

$.getJSON('<?php echo $this->Html->url(array('controller'=>'accounts', 'action'=>'get_customers_order_mcs')); ?>/'+customer_order_id,
                function(data){
                    var json_mc = data.MasterCarton.mc;
                    alert(json_mc);
                    $.each(json_mc,function(){
                         console.log(this);
                   });
             });

作为响应发送的数据如下-

{
     "MasterCarton":{
                         "id":"40",
                         "mc":"[
                                    "1":{\"mc_number\":\"Warehouse1\\\/2013-2014\\\/CO\\\/ABC Corp\\\/239\\\/101-Red-1\",\"config\":{\"S2\":10,\"S1\":10},\"delivered\":0},            "2":{\"mc_number\":\"Warehouse1\\\/2013-2014\\\/CO\\\/ABC Corp\\\/239\\\/101-Red-2\",\"config\":{\"S2\":10,\"S1\":10},\"delivered\":0},                  "3":{\"mc_number\":\"Warehouse1\\\/2013-2014\\\/CO\\\/ABC Corp\\\/239\\\/104-Black-3\",\"config\":{\"S1\":7,\"S2\":7,\"S5\":6},\"delivered\":0},               "4":{\"mc_number\":\"Warehouse1\\\/2013-2014\\\/CO\\\/ABC Corp\\\/239\\\/104-Black-4\",\"config\":{\"S1\":7,\"S2\":7,\"S5\":6},\"delivered\":0},              "5":{\"mc_number\":\"Warehouse1\\\/2013-2014\\\/CO\\\/ABC Corp\\\/239\\\/104-Black-5\",\"config\":{\"S1\":6,\"S2\":6,\"S5\":7},\"delivered\":0}
                               ]",
                         "delivery_note_id":"0",
                         "customer_order_id":"314"
                 }
}

mc内部的json数组如下图-

[
   "1":{
      "mc_number":"Warehouse1\/2013-2014\/CO\/ABC Corp\/239\/101-Red-1",
      "config":{
         "S2":10,
         "S1":10
      },
      "delivered":0
   },
   "2":{
      "mc_number":"Warehouse1\/2013-2014\/CO\/ABC Corp\/239\/101-Red-2",
      "config":{
         "S2":10,
         "S1":10
      },
      "delivered":0
   },
   "3":{
      "mc_number":"Warehouse1\/2013-2014\/CO\/ABC Corp\/239\/104-Black-5",
      "config":{
         "S1":6,
         "S2":6,
         "S5":7
      },
      "delivered":0
   }
]

我尝试使用jquery解析其中的每个对象，每个对象如下-

    {
   "mc_number":"Warehouse1\/2013-2014\/CO\/ABC Corp\/239\/101-Red-1",
   "config":{
      "S2":10,
      "S1":10
   },
   "delivered":0
}

要获取上述对象，我使用以下 jquery 代码-

$.each(json_mc,function(){
       // What should the code be so as to get each individual objects.         
});

这就是 .each 的每一次都应该让我——

   {
      "mc_number":"Warehouse1\/2013-2014\/CO\/ABC Corp\/239\/101-Red-1",
      "config":{
         "S2":10,
         "S1":10
      },
      "delivered":0
   }

Answer 1

您所追求的只是在每次迭代时设置的this:

$.each(json_mc,function(){
    console.log(this);
});

更新

鉴于您显示的原始响应，您可能需要再解码一次:

$.each($.parseJSON(json_mc), function() {
    console.log(this);
});
