我正在尝试在 Windows 应用商店应用程序中使用 Bing 地图进行反向地理编码。我的请求（使用 WinJS.xhr）通过就好了，我从他们的示例页面得到了与此类似的响应：

}

但是，当我在数据上调用 JSON.parse 并尝试显示它时，它返回的只是

[object Object]

我究竟做错了什么？

正如其他人所提到的，它确实解析了，你只是不认识结果。

JSON是将对象层次结构序列化为字符串。

JSON.parse(...)将 JSON 序列化（字符串）转换回对象层次结构。

无法显示对象的层次结构——它可以被遍历！-- 您需要将其编码为可以显示的内容（例如 HTML）。

为此，您需要遍历对象层次结构以构建 HTML 片段字符串。innerHTML然后，您可以通过现有元素（例如容器 DIV）的属性简单地将其添加到 HTML DOM 。
