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。没有数据显示。我按照说明使用了api 但我的应用程序根本无法加载数据。知道什么地方可能出问题吗？！[天气应用]（https://www.pinterest.com/pin/101682904073182759

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

我仅更改声明顺序（将所有类声明：UI, Storage, Weather移至顶部），它在jsfiddle here中有效（但由于SecurityError而在SO代码段中无效），因此您需要更改顺序html文件底部的脚本声明为：

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

天气应用，openweathermap.org / api数据未加载
