ebay api jquery在回調中未捕獲的引用錯誤

我正在使用一個簡單的eBay jQuery插件。它成功打電話。它返回一個結果。但是，當它試圖找到我的回調函數時，會收到「Uncaught ReferenceError：_cb_findItemsByKeywords is not defined」。ebay api jquery在回調中未捕獲的引用錯誤

您的回調函數未在全局範圍中定義，因此調用腳本無法達到該回調函數。

您需要爲每個回調方法指定一個唯一的名稱並將其添加到窗口中。

var uniqueName = "_cb_" + $.now(); 
window[uniqueName] = function (root) { 
    /* your stuff */ 

    window[uniqueName] = null; 
}

然後將該唯一名稱傳遞給ebay api，作爲該腳本的所需回調函數fn。

感謝您的快速回復。給它一個鏡頭。 – Mars7272

您可以將ebay調用包裝在jquery ajax調用中，響應會自動鏈接到填充了根變量的_cb_findItemsByKeywords方法。

有一個例子頁：

<html> 
<head> 
<title>eBay Search Results</title> 
<script src="http://code.jquery.com/jquery-latest.js"></script> 
<style type="text/css">body { font-family: arial,sans-serif;} </style> 

    <script type="text/javascript"> 
    $(document).ready(function() { 

     $("#ebay").click(function(e){ 

      var url = "http://svcs.ebay.com/services/search/FindingService/v1?SECURITY-APPNAME=Reddeneg-2a4d-4b23-8d37-defc1bbb868f&OPERATION-NAME=findItemsByKeywords&SERVICE-VERSION=1.0.0&RESPONSE-DATA-FORMAT=JSON&callback=_cb_findItemsByKeywords&REST-PAYLOAD&keywords=termo&paginationInput.entriesPerPage=30"; 

      $.ajax({ 
      url: url, 
      dataType: "script" 
      }); 

     }); 

    }); 

    function _cb_findItemsByKeywords(root) { 
     var items = root.findItemsByKeywordsResponse[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; 

     if (null != title && null != viewitem) { 
      html.push('<tr><td>' + '<img src="' + pic + '" border="0">' + '</td>' + 
      '<td><a href="' + viewitem + '" target="_blank">' + title + '</a></td></tr>'); 
     } 
     } 
     html.push('</tbody></table>'); 
     document.getElementById("results").innerHTML = html.join(""); 
    } 

    </script> 

</head> 
<body> 
<h1>eBay Search</h1> 

<a id="ebay" href="#"> run Ebay Query</a> 

<div id="results"></div> 


</body> 
</html>

答案提供alejo實際工作，但是我將修改它一下。 jQuery ajax調用支持dataType：'jsonp'，它添加了'callback =？'默認爲url，並允許您將回調函數定義爲ajax調用的成功屬性。您還可以使用數據屬性來傳遞查詢參數

<html> 
<head> 
<title>eBay Search Results</title> 
<script src="http://code.jquery.com/jquery-latest.js"></script> 
<style type="text/css">body { font-family: arial,sans-serif;} </style> 
<script type="text/javascript"> 
$(document).ready(function() { 
    $("#ebay").click(function(e){ 
     var url = "http://svcs.ebay.com/services/search/FindingService/v1?SECURITY-APPNAME=Reddeneg-2a4d-4b23-8d37-defc1bbb868f&OPERATION-NAME=findItemsByKeywords&SERVICE-VERSION=1.0.0&RESPONSE-DATA-FORMAT=JSON&REST-PAYLOAD&paginationInput.entriesPerPage=30"; 
     $.ajax({ 
     url: url, 
     dataType: "jsonp", 
     data: {keywords: 'thermo'}, 
     success: function(root){ 
      var items = root.findItemsByKeywordsResponse[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; 

       if (null != title && null != viewitem) { 
        html.push('<tr><td>' + '<img src="' + pic + '" border="0">' + '</td>' + 
        '<td><a href="' + viewitem + '" target="_blank">' + title + '</a></td></tr>'); 
       } 
      } 
      html.push('</tbody></table>'); 
      document.getElementById("results").innerHTML = html.join(""); 
     } 
     }); 
    }); 
}); 
    </script> 
</head> 
<body> 
<h1>eBay Search</h1> 
<a id="ebay" href="#"> run Ebay Query</a> 
<div id="results"></div> 
</body> 
</html>
