Titanium - Json 对象返回一个空数组

Question

我的 WEC 网络服务返回一个 JSON 对象，我想在我的 Titanium 应用程序中使用它，但问题是，JSON 对象中有数组，我可以在控制台中看到它们，但是当我尝试通过提供访问时索引，它不起作用。

示例

}

在这里，我可以使用 JSON.parse 访问 GetDoctorFavoriteTestResult.CountryList，但是当我尝试获取数组时 GetDoctorFavoriteTestResult.TestDetails它显示为空。

即使在浏览器中，Web 服务也能完美运行。

再次，我可以在 Titanium 控制台窗口中看到数组数据。

有什么办法吗？

Answer 1

安装此 chrome 扩展程序。它会自动为您提供 Titan 应用程序的路径

谢谢

Answer 2

会更容易看到你是如何解析 json 的

试试这个： GetDoctorFavoriteTestResult[0].TestDetails
