移调json对象数组

Question

我必须迭代“price_detail”json数组对象。请教我如何重新研究这种类型的对象。我已经穿过很多结构，但不是这种类型。我无法找到这种类型的数据结构的搜索

码I使用“嵌套通过JSON对象阵列迭代”的一个例子：

 $.each(json.data['price_detail'], function (i, item) { 
     console.log('name='+ i + ' value=' +item); 
     } 

    output: 
    name=price value=14.7,14.7,14.7 
    name=type value=coupon,coupon,coupon 
    name=savings value=,75%,35% 
    name=pharmacy value=Walmart,Kmart,Costco 

数据具有如下的结构。

{"errors": [], 
      "data": {"form": "tablet", 
      "price_detail": 
       {"price": [14.7, 14.7, 14.7], 
       "type": ["coupon", "coupon", "coupon"], 
       "savings": [null, "75%", "35%"], 
       "pharmacy": ["Walmart", "Kmart", "Costco"]},      
       "brand": ["lortab", "maxidone", "vicodin", "norco", "xodol", "hycet"], 
       "dosage": "5mg/325mg", "generic": ["hydrocodone/acetaminophen", "lorcet", "zolvit"], 
       "prices": [14.7, 14.7, 14.7], 
       "quantity": 60, 
       "display": "Lortab, Maxidone, Vicodin, Norco, Xodol, Hycet (hydrocodone/acetaminophen, lorcet, zolvit)", 
       "manufacturer": "generic"}, 
       "success": true} 

我想要一个使用制药，类型，节省和价格的对象;如：

 { 
      ["Walmart", "coupon", NULL, 14.7], 
      ["Kmart", "coupon", "75%", 14.7], 
      ["Costco","coupon", "35%", 14.7] 
     } 

谢谢。

编辑：我改变了标题。淘宝网后，我发现我需要调换json结果。请原谅我缺乏术语。

我试图使用此功能，我发现转置的阵列

function transpose(a) { 
     return Object.keys(a[0]).map(function (c) { 
      return a.map(function (r) { 
       return r[c]; 
      }); 
     }); 
    } 

创建的测试数据，通过功能

var testData = [ [14.7, 14.7, 14.7], 
         ["coupon", "coupon", "coupon"], 
         [null, "75%", "35%"], 
         ["Walmart", "Kmart", "Costco"] 
       ] 
         var result = transpose(testData); 

运行它这使我所期望的结果。

[14.7, "coupon", null, "Walmart"], 
    [14.7, "coupon", "75%", "Kmart"], 
    [14.7, "coupon", "35%", "Costco"] 

现在，当我跑我的“price_detail”对象通过它

transpose(json.data['price_detail']); 

我陷在这样的错误：遗漏的类型错误：无法转换未定义或为空反对

你规定所需的输出不是有效的JSON，但是这里有一个例子可以产生我认为对你有用的格式。如果它不是你想要的，你现在可以看到如何修改它以适应你。

var json = { 
 
    "errors": [], 
 
    "data": { 
 
    "form": "tablet", 
 
    "price_detail": { 
 
     "price": [14.7, 14.7, 14.7], 
 
     "type": ["coupon", "coupon", "coupon"], 
 
     "savings": [null, "75%", "35%"], 
 
     "pharmacy": ["Walmart", "Kmart", "Costco"] 
 
    }, 
 
    "brand": ["lortab", "maxidone", "vicodin", "norco", "xodol", "hycet"], 
 
    "dosage": "5mg/325mg", 
 
    "generic": ["hydrocodone/acetaminophen", "lorcet", "zolvit"], 
 
    "prices": [14.7, 14.7, 14.7], 
 
    "quantity": 60, 
 
    "display": "Lortab, Maxidone, Vicodin, Norco, Xodol, Hycet (hydrocodone/acetaminophen, lorcet, zolvit)", 
 
    "manufacturer": "generic" 
 
    }, 
 
    "success": true 
 
}; 
 

 
var result = []; 
 

 
for (var i = 0; i < json.data.price_detail.pharmacy.length; i++) { 
 
    result.push({ 
 
    "pharmacy": json.data.price_detail.pharmacy[i], 
 
    "type": json.data.price_detail.type[i], 
 
    "savings": json.data.price_detail.savings[i], 
 
    "price": json.data.price_detail.price[i] 
 
    }); 
 
} 
 
console.log(JSON.stringify(result));
