Question

我尝试使用var price = item.price;和var condition = item.condition;来定义变量，但是它们是未定义的。 eBay API参考似乎没有解释如何解析然后显示此信息。

<div id="api"></div>


<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;
    var price    = item.price;
    var condition= item.condition;
    if (null != title && null != viewitem)
    {
      html.push(
        '<tr id="api_microposts"><td>'
         + '<img src="' + pic + '" border="0" width="190">' + '<a href="' + viewitem + '" target="_blank">' + title + 
         '</a>' + '<br>' + price + '</td></tr>');
    }
  }
  html.push('</tbody></table>');
  document.getElementById("api").innerHTML = html.join("");




// Define global variable for the URL filter
var urlfilter = "";


// Generates an indexed URL snippet from the array of item filters
function  buildURLArray() {
  // Iterate through each filter in the array
  for(var i=0; i<filterarray.length; i++) {
    //Index each item filter in filterarray
    var itemfilter = filterarray[i];
    // Iterate through each parameter in each item filter
    for(var index in itemfilter) {
      // Check to see if the parameter has a value (some don't)
      if (itemfilter[index] !== "") {
        if (itemfilter[index] instanceof Array) {
          for(var r=0; r<itemfilter[index].length; r++) {
          var value = itemfilter[index][r];
          urlfilter += "&itemFilter\(" + i + "\)." + index + "\(" + r + "\)=" + value ;
          }
        }
        else {
          urlfilter += "&itemFilter\(" + i + "\)." + index + "=" + itemfilter[index];
        }
      }
    }
  }
}  // End buildURLArray() function

// Execute the function to build the URL filter
buildURLArray(filterarray);

url += urlfilter;



}

Answer 1

不确定为什么情况不会出现：http://developer.ebay.com/Devzone/finding/CallRef/types/SearchItem.html

似乎你正在寻找unitPrice和condition.conditionDisplayName

Answer 2

Ebay的例子并不是很有帮助。您可以使用他们的快速入门示例和明智地使用JSON.stringify（）来查看返回对象的样子。

var price = item.sellingStatus[0].currentPrice[0]["__value__"];
var condition = item.condition[0].conditionDisplayName[0];

（请注意，如果您正在进行非本地货币查询，则可能需要 convertedCurrentPrice 。）

无法使用eBay API显示商品的价格或条件
