Jquery 如何获取JSON对象的某些部分并将它们作为选项添加到SELECT中？

我有一个json文件，包含很多信息

我需要获得每个产品的ProductID和描述，并用它们填充一个选择/选项列表

<div>
      <button id="getButton">Get</button>
      <select id="populate">
          <option>control</option>
      </select>
</div>

得到
控制

这是简单的HTML，我尝试了以下jQuery：

$(document).ready(function() {
    //attach a jQuery live event to the button
    $('#getButton').live('click', function() {
        $.getJSON('json.json', function(data) {
            $.each(data, function(entryIndex, entry) {
                items.push('<option value="' + entry['ProductID'] + ">' + entry ['Description'] + '</option>');
  });
        });
    });
});​

$（文档）.ready（函数（）{
//将jQuery live事件附加到按钮
$（'#getButton'）.live（'单击'，函数（））{
$.getJSON（'json.json'，函数（数据）{
$.each（数据、函数（entryIndex、条目）{
items.push（“”+条目['Description']+“”）；
});
});
});
});​

我也尝试过不同版本的代码，但都没有用。我错过了什么重要的东西吗？json格式可能有误吗

值得注意的是，我以前从未使用过任何json/ajax，因此这是一个全新的领域：）

谢谢

完整的json以及脚本和html也可以在这里找到

有几个问题：

用于将

选项

添加到

#填充

下拉列表中

push

用于向数组中添加元素

您的产品包含在json对象的

products

数组中。因此，不要迭代

数据

，而是迭代

数据.ListProductsResponse.Products

有一个小语法错误，因为您没有关闭

.each（）

中的

“>

字符串

下面是一个固定的示例：

var $select = $("#populate");
$.each(data.ListProductsResponse.Products, function(entryIndex, entry) {
