最近在研究yahoo的天气api。
挺好用的，不过返回数据都是英文。网上找了中英文对照。稍后放详细开发教程。
源码放出。在开发中有几个问题这里重点提一下。
第一 关于数字显示。比如9点 从美观上考虑需要 加上0 显示为 09:01分。这样会好看。则需要对比系统时间 当小于10的时候String 然后前边加上0.月份和日期做相同处理。
当flash加载yahoo的图片时候。跨预加载有时候本地会不现实。在loader中添加一个LoaderContext 即可。
如下：
var isr:String = o.imageURL;
//trace(isr);
var iid:Array = isr.match(/[0-9]./g);
var lo:Loader=new Loader();
var lc:LoaderContext = new LoaderContext(true);
lo.load(new URLRequest(“http://l.yimg.com/a/i/us/nws/weather/gr/”+iid[1]+”d.png”),lc);
lo.contentLoaderInfo.addEventListener(Event.COMPLETE,showit);
需要说明的是 yahoo返回的数据中默认的图片是一种很小的gif。
如图：
我个人喜欢加载那个大png透明图。
通过正则获得接口返回的图片编号，然后加载对应的png。
注意上边那个范例就是如此处理的。
