IT技术代码

java web service实现天气预报功能前台js界面代码：
//省份
function LoadProvince() {
$.ajax({
type: "POST",
url: "ashx/weatherHandler.ashx",
data: "option=province",
success: function (result) {
$(".sel-province option").remove();
var arry = result.split('|');
var obj = null;
for (var i = 0; iarry.length; i++) {
if (arry[i] != nullarry[i] != "") {
obj = arry[i].split(',');
$(".sel-province").append("option value='" + obj[1] + "'" + obj[0] + "/option");
}
}
$(".sel-province").find("option[text='北京']").attr("selected", "selected");
},
error: function (errorMsg) {
$(".result-table tr").remove();
$(".result-table").append("trtd省份请求出现错误，请您稍后重试 。。。/td/tr");
}
});
}
//城市
function LoadCity(provinceid) {
$.ajax({
type: "POST",
url: "ashx/weatherHandler.ashx",
data: "provinceid=" + provinceid + "option=city",
success: function (result) {
$(".sel-city option").remove();
var arry = result.split('|');
var obj = null;
for (var i = 0; iarry.length; i++) {
if (arry[i] != nullarry[i] != "") {
obj = arry[i].split(',');
$(".sel-city").append("option value='" + obj[1] + "'" + obj[0] + "/option");
}
}
},
error: function (errorMsg) {
$(".result-table tr").remove();
$(".result-table").append("trtd城市请求出现错误，请您稍后重试 。。。/td/tr");
}
});
}
//加载天气
function GetWeather(cityid) {
$.ajax({
type: "POST",
url: "ashx/weatherHandler.ashx",
data: "cityid=" + cityid + "option=weather",
success: function (result) {
$(".result-table tr").remove();
var arry = result.split('|');
var obj = null;
for (var i = 0; iarry.length; i++) {
if (arry[i] != nullarry[i] != "") {
if (arry[i].indexOf(".gif")0) {
$(".result-table").append("trtdimage src='https://www.04ip.com/post/images/" + arry[i] + "'//td/tr");
}
else {
$(".result-table").append("trtd" + arry[i] + "/td/tr");
}
}
}
},
error: function (errorMsg) {
$(".result-table tr").remove();
$(".result-table").append("trtd天气数据请求出现错误 ， 请您稍后重试 。。。/td/tr");
}
});
}
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
【java各地天气预报代码 java天气预报程序】/// /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"]);
