从 JQuery.ajax 成功数据中解析 JSON

我无法从JQery获取JSON对象的内容.阿贾克斯电话.我的电话:

$('#Search').click(function () {
    var query = $('#query').valueOf();
    $.ajax({
        url: '/Products/Search',
        type: "POST",
        data: query,
        dataType: 'application/json; charset=utf-8',
        success: function (data) {
            alert(data);
            for (var x = 0; x < data.length; x++) {
                content = data[x].Id;
                content += "<br>";
                content += data[x].Name;
                content += "<br>";
                $(content).appendTo("#ProductList");
               // updateListing(data[x]);
            }
        }
    });
});

It seems that the JSON object is being returned correctly because "alert(data)" displays the following

[{"Id": "1", "Name": "Shirt"}, {"Id": "2", "Name":"Pants"}]

但当我try 使用以下命令在页面上显示Id或名称时:

content = data[x].Id;
content += "<br>";
content += data[x].Name;
content += "<br>";

it returns "undefined" to the page. What am I doing wrong?

Thanks for the help.
