html代码：
body
form id="form1" runat="server"
div class="head-div"
table
tr
td
select class="sel-province sel"
/select
/td
td
select class="sel-city sel"
/select
/td
td
input type="button" class="btn-search" value="https://www.04ip.com/post/查询" /
/td
/tr
/table
/div
div class="result-div"
table class="result-table"
/table
/div
/form
/body
由于js不支持跨域，直接ajax+ashx一般处理程序（在里面调用天气接口） 。一般处理程序代码如下：
using System.Web;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Text;
namespace WeatherTest.ashx
{
/// summary
/// weatherHandler 的摘要说明
/// /summary
public class weatherHandler : IHttpHandler
{
WeatherWsClient.WeatherWSSoapClient client = new WeatherWsClient.WeatherWSSoapClient();
public void ProcessRequest(HttpContext context)
{
context.Response.ContentType = "text/plain";
string[] result = null;
string option = context.Request.Form["option"];
switch (option)
{
case "province":
result = GetProvinces();
break;
case "city":
result = GetCitys(context.Request.Form["provinceid"]);
break;
case "weather":
result = GetWeather(context.Request.Form["cityid"], null);
break;
}
string str = ConvertToString(result, option);
context.Response.Write(str);
}
/// summary
/// 数组转字符串
/// /summary
/// param name="result"/param
/// param name="option"/param
/// returns/returns
private string ConvertToString(string[] result, string option)
{
StringBuilder sb = new StringBuilder();
foreach (string item in result)
{
sb.Append(item+"|");
}
return sb.ToString();
}
/// summary
/// 省份
/// /summary
/// returns/returns
private string[] GetProvinces()
{
return client.getRegionProvince();
}
/// summary
/// 城市
/// /summary
/// param name="provinceid"/param
/// returns/returns
private string[] GetCitys(string provinceid)
{
return client.getSupportCityString(provinceid);
}
/// summary
/// 天气数据
/// /summary
/// param name="cityid"/param
/// param name="userid"/param
/// returns/returns
private string[] GetWeather(string cityid, string userid)
{
return client.getWeather(cityid, userid);
}
public bool IsReusable
{
get
{
return false;
}
