嵌套JSONP响应的正确索引



给定此嵌套的JSON响应

{
"findCompletedItemsResponse":[  
  {  
     "ack":[  
        "Success"
     ],
     "version":[  
        "1.13.0"
     ],
     "timestamp":[  
        "2017-11-28T19:23:07.161Z"
     ],
     "searchResult":[  
        {  
           "@count":"2",
           "item":[  
              {  
                 "itemId":[  
                    "222664349999"
                 ],
                 "title":[  
                    "Nikon IK467-156 Remote Terminal Cover 10-Pin for  D2X, D2Xs, D2H, F5, F90, F100"
                 ],
                 "globalId":[  
                    "EBAY-ENCA"
                 ],
                 "galleryURL":[  
                    "http://thumbs4.ebaystatic.com/m/mvCz__whMmEvIJIvq0Li1qQ/140.jpg"
                 ],
                 "viewItemURL":[  
                    "http://www.ebay.com/itm/Nikon-IK467-156-Remote-Terminal-Cover-10-Pin-D2X-D2Xs-D2H-F5-F90-F100-/222664349999"
                 ],
                 "paymentMethod":[  
                    "PayPal"
                 ],
                 "autoPay":[  
                    "false"
                 ],
                 "postalCode":[  
                    "B2R1C3"
                 ],
                 "location":[  
                    "Canada"
                 ],
                 "country":[  
                    "CA"
                 ],
                 "sellingStatus":[  
                    {  
                       "currentPrice":[  
                          {  
                             "@currencyId":"CAD",
                             "__value__":"5.0"
                          }
                       ],

value 的索引是什么?我目前正在通过此代码访问上方的所有内容:

 var items = result.findCompletedItemsResponse[0].searchResult[0].item || [];
 var html = [];
 html.push('<table width="100%" border="0" cellspacing="0" cellpadding="3"><tbody>');
for (var i = 0; i < items.length; ++i) {
   var item     = items[i];
   var title    = item.title;
   var pic      = item["galleryURL"];
   var viewitem = item.viewItemURL;
   var sellPrice = item.sellingStatus[0]["currentPrice"]["_value_"];

我试图将sellprice设置为JSON响应中 value 条目的值,但似乎无法找出适当的语法来访问索引。

感谢您的回复。不幸的是,该方法无效。仍在试图解决这个问题。我也尝试了以下代码,但我遇到了同样的错误:

var sellPrice=result.findCompletedItemsResponse[0].searchResult[0].item[0].sellingStatus[0].convertedCurrentPrice || [];
for (var j = 0; j < sellPrice.length; ++j) {
    var convertedCurrentPrice = sellPrice[j];
    var soldPrice = convertedCurrentPrice["_value_"];

对于记录,我试图在响应中访问convertedCurrentPrice值,而不是我最初说明的当前值。仍然没有运气。也在四处寻找教程,但到目前为止,还没有发现任何深入索引中的JSONP的内容。有人知道有什么教程涵盖了这一点吗?再次感谢。

var sellPrice = item.sellingStatus[0]["currentPrice"][0]["_value_"];

CurrentPrice是一个具有单个货币块的数组
