透明天气预报代码

       很高兴有机会参与这个透明天气预报代码问题集合的讨论。这是一个多元且重要的话题，我将采取系统的方法，逐一回答每个问题，并分享一些相关的案例和观点。

1.求～一行天气预报代码（附参考站）

2.求天气预报代码

3.html添加天气预报代码

4.小学四年级科学表示气象符号有哪些

5.php获取天气预报的代码

6.ASP.NET实现天气预报

求～一行天气预报代码（附参考站）

       发送到这个网站的一个网址，会自动返回此城市的天气信息。对此信息再格式化就好了。

       这是泰安的天气预报代码，看你需要那种样式

       样式一代码：<iframe src="/wmaps/xml/%s.xml";
