第三个接口，返回信息比较全面，下面使用第三个接口实例。
返回值中图片链接我使用http://www.36wu.com/WeatherPic.aspx中的图标，天气图标名称与返回数据大致相符！<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>weather</title> <script type="text/javascript" src="jquery-1.4.1.js"></script> </head> <body> </body> </html> <script type="text/javascript"> var _city="";//城市 var _temp="";//温度 var _weather="";//天气状态 var _weather_img=""; var weatherUrl="http://m.weather.com.cn/data/101190801.html"; //此处101190801为 江苏徐州城市 代码，文章下面有具体城市信息。 $.ajax({ type: 'GET', url: weatherUrl, dataType: "json", success: function(html) { if(html) { _city= html["weatherinfo"]["city"]; _temp=html["weatherinfo"]["temp1"]; _weather=html["weatherinfo"]["weather1"]; _weather_img=getWeatherImg(html["weatherinfo"]["img1"]); } else { //网络异常/数据获取出错后显示默认配置天气 _city= "徐州"; _temp="24℃~17℃"; _weather="晴天"; _weather_img=getWeatherImg(0); } } }); document.write("<span style='font-size:13px;'>"+_city +_weather_img+ _temp+"<span style='margin-left:5px;'></span>"+_weather+"</span>"); function getWeatherImg(id) { var number =""; if(id < 10) number ="0"+id; else {number=""+id; if(id=="99") number="02";}//99暂时没懂是什么图标，不处理。研究明白的亲，请指教！ return "<img src='../images/weather_img/"+number+".png' title='"+_weather+"' style='margin:0px 5px 0px 5px; width:16px; height:16px;' />"; } </script>

下列内容为网上一些杂信息，我整理有能用的看看：1. XML接口 http://flash.weather.com.cn/wmaps/xml/china.xml 这个是全国天气的根节点，列出所有的省，其中的pyName字段是各个省XML的文件名，比如北京的是beijing，那就意味着北京的XML地址为 http://flash.weather.com.cn/wmaps/xml/beijing.xml 一个省的天气，其中列出该省各个市的数据，北京就列出各个区。 tmp1是最低温低，tmp2是最高温度，url非常重要，我们一会儿再说。state1和state2是神马转神马，每个数代表一个天气现象。天气现象非常多，我本想全部分析出来，后来直接放弃了这个想法。因为我看到了一个城市的天气现象的编码是26...我现在知道的有0.晴 1.多云 2.阴 6.雨夹雪 7.小雨 8.中雨 13.阵雪 14.小雪 其中后来发现知道这个没用，这个数字的主要作用是检索图片的！！！ 2. 图片接口 http://m.weather.com.cn/img/c0.gif http://m.weather.com.cn/img/b0.gif http://www.weather.com.cn/m/i/weatherpic/29x20/d0.gif http://www.weather.com.cn/m2/i/icon_weather/29x20/n00.gif 这个图就是天气现象0（晴）的图片，其他天气现象的图片依此类推。c打头的图片是20*20像素的，b打头的是50*46像素的，d打头的是反白的图标，29*20像素，n打头的是夜间反白图标，29*20像素，注意这里的文件名是两位数字！ 也许还有更多的图标，等待大家发掘啦~ 3. JSON接口 真没想到~居然有JSON接口~JSON在iPhone上分析起来要比XML简单很多 http://m.weather.com.cn/data/101010200.html 这个是北京的JSON数据，那个HTML的名字是根据上文XML中的url得到的。这个JSON中包含了实时数据、7天天气预报、气象指数等丰富的数据 获取省级代码：http://www.weather.com.cn/data/list3/city.xml?level=1 获取城市代码(比如安徽是22)：http://www.weather.com.cn/data/list3/city22.xml?level=2 获取区域代码（比如安庆是2206）：http://www.weather.com.cn/data/list3/city2206.xml?level=3 获取到安徽省安庆市望江县的代码是220607 然后去加上中国代码请求URL：http://m.weather.com.cn/data/101220607.html 就可以获取当地天气。 另外再给几个有用的探索得到的URL： 天气 FLASH实况：http://flash.weather.com.cn/sk2/101220607.xml 实况FLASH：http://flash.weather.com.cn/sk2/shikuang.swf?id=101220607 三级选择菜单（注明，这里有四个INPUT，其中有一个被隐藏了，可用FIREFOX改下源代码查看）：http://www.weather.com.cn/static/custom/search3.htm 实时天气（很有用哦）：http://www.weather.com.cn/data/sk/101220607.html
