html5代码编写天气预报_天气预报代码html代码
1.网页天气预报代码的问题
2.android端免费获取天气信息的服务器接口有么
3.ASP.NET实现天气预报
4.用html如何从其他网站获得天气预报数据
之前做过相关的App，网上搜出来的，直接粘贴了。有用请采纳哦~
国家气象局提供的天气预报接口
接口地址：
对于第三个接口，返回信息比较全面，也是以json格式提供，格式如下

1. XML接口 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 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的！！！
2. 接口 这个图就是天气现象0（晴）的，其他天气现象的依此类推。c打头的是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 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：获取城市代码(比如安徽是22)：获取区域代码（比如安庆是2206）：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：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：实况FLASH：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）：实时天气（很有用哦）： XML接口

我的网站用的代码：酒嘉市场信息网
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="" width=178 height=248 marginwidth=0 marginheight=0 hspace=0 vspace=0 frameborder=0 scrolling=no align=center id=url></iframe>
样式二代码：<iframe src="" width=178 height=248 marginwidth=0 marginheight=0 hspace=0 vspace=0 frameborder=0 scrolling=no align=center id=url></iframe>
样式三滚动代码：<iframe src="" width=178 height=21 marginwidth=0 marginheight=0 hspace=0 vspace=0 frameborder=0 scrolling=no align=center id=url></iframe>
天气代码高级使用方法：
如果您会HTML语言，您还可以在iframe代码中的url后面加参数，如：
chengshi_321.html?c0=F9DC68&c1=white&c2=FEFCE0&t1=red&bg=white&w=178&h=250&text=no
其中 c0 表示 表格第一行背景颜色，c1，c2表示表格其他行间隔的背景颜色，t1表示 标题颜色，bg 表示页面北京颜色，w表示表格宽度 h 表示表格高度
当 text=yes 时，将会出现滚动的天气文字，建议您自己调试看看，如：
chengshi_321.html?c0=red&c1=FF9900&bg=F4FFF4&w=178&h=20&text=yes
注意：颜色请不要加 # 符号，如 #FF9900 请写成 FF9900
欢迎访问我的网站
android端免费获取天气信息的服务器接口有么
www.T7ONLINE.COM
我刚刚学习网站制作，还没有做成一个网站呢
想在网站内加入新浪的天气预报
我首先试了一下，在自己的电脑上，用记事本编辑
<html>
<head>
</head>
<body>
<iframe src="" frameborder="0" width="117" height="37" marginheight="0" marginwidth="0" scrolling="no"></iframe>
</body>
<html>
保存为html格式
打开后为什么是显示的北京的天气状况？这个代码是可以随ip变化的啊！
问题补充：新浪首页（www.sina.com)天气预报我这里怎么也显示的是北京的天气情况？难道它不是根据ip来显示的吗？
ASP.NET实现天气预报
中国国家气象局提供了获取所在城市天气预报信息接口。通过这个接口，我们就可以获取天气信息了。
关于获取天气预报的实例参考android学习手册，里面有源码。android学习手册包含9个章节，108个例子，源码文档随便看，例子都是可交互，可运行，源码采用android studio目录结构，高亮显示代码，文档都采用文档结构图显示，可以快速定位。360手机助手中下载,图标上有贝壳
中国国家气象局天气预报接口总共提供了三个：
注：上面接口2014.3.4日已不再更新。换成这个：。各位看34楼。在此感谢tdwll和黄晓佳cobish。
最详细的信息来自第三个接口。上面url中的101010100是城市代码，这里是北京的城市代码。只需要改变城市代码，就可以得到所在城市的天气信息。笔者在福州，所以选择的城市代码是福州101230101。
在浏览器上输入url：得到信息，天气信息是json的数据格式，数据如下：
{"weatherinfo":{"city":"福州","city_en":"fuzhou","date_y":"2012年5月14日","date":"","week":"星期一","fchh":"08","cityid":"101230101","temp1":"29℃~23℃","temp2":"26℃~20℃","temp3":"24℃~20℃","temp4":"25℃~20℃","temp5":"24℃~21℃","temp6":"25℃~22℃","tempF1":"84.2℉~73.4℉","tempF2":"78.8℉~68℉","tempF3":"75.2℉~68℉","tempF4":"77℉~68℉","tempF5":"75.2℉~69.8℉","tempF6":"77℉~71.6℉","weather1":"阵雨转中雨","weather2":"中雨转小雨","weather3":"小雨","weather4":"小雨","weather5":"小雨转阵雨","weather6":"阵雨转小雨","img1":"3","img2":"8","img3":"8","img4":"7","img5":"7","img6":"99","img7":"7","img8":"99","img9":"7","img10":"3","img11":"3","img12":"7","img_single":"3","img_title1":"阵雨","img_title2":"中雨","img_title3":"中雨","img_title4":"小雨","img_title5":"小雨","img_title6":"小雨","img_title7":"小雨","img_title8":"小雨","img_title9":"小雨","img_title10":"阵雨","img_title11":"阵雨","img_title12":"小雨","img_title_single":"阵雨","wind1":"微风","wind2":"微风","wind3":"微风","wind4":"微风","wind5":"微风","wind6":"微风","fx1":"微风","fx2":"微风","fl1":"小于3级","fl2":"小于3级","fl3":"小于3级","fl4":"小于3级","fl5":"小于3级","fl6":"小于3级","index":"热","index_d":"天气较热，建议着短裙、短裤、短套装、T恤等夏季服装。年老体弱者宜着长袖衬衫和单裤。","index48":"暖","index48_d":"较凉爽，建议着长袖衬衫加单裤等春秋过渡装。年老体弱者宜着针织长袖衬衫、马甲和长裤。","index_uv":"弱","index48_uv":"最弱","index_xc":"不宜","index_tr":"适宜","index_co":"较不舒适","st1":"27","st2":"21","st3":"24","st4":"18","st5":"22","st6":"18","index_cl":"较不宜","index_ls":"不太适宜","index_ag":"不易发"}}
我们可以解析json数据去得到自己想用的天气信息。
