我没有从 openweathermap.org/api 获取数据。我从 openweathermap.org/api 获取 API 密钥和安全密钥。不显示任何数据。我按照说明使用了 API但是我的应用程序根本不加载数据。知道可能出现什么问题吗？![天气应用]（https://www.pinterest.com/pin/101682904073182759

代码在我的GitHub帐户上：https://github.com/nansol/WeatherApp

我只更改声明序列（将所有类声明：UI, Storage, Weather移动到顶部）它在这里的jsfiddle中工作（但由于tu SecurityError，在SO代码段中不起作用）因此，您需要将html文件底部的脚本声明顺序更改为：

<script src="ui.js"></script>
<script src="weather.js"></script>
<script src="storage.js"></script>
<script src="index.js"></script>
