WEB前端工程师(实践)制作天气预报难度:简单

需要准备:jQuery Bootstrap 天气预报API(本文中使用API可能会失效请灵活运用)

CSS样式可以你自己去写这里只提出jQuery 请求数据和解析JSON数据

	"reason":"successed!",

上面是要用到的JSON数据格式

搭建界面略过 根据JSON中数据添加到HTML中

 

解析数据到HTML中 其中一定要注意 跨域问题

$(document).ready(function() {
$.ajax({
type : "POST",
dataType:'JSONP',//跨域
jsonp:"callback",
jsonpCallback:"fanyi",
url:"http://v.juhe.cn/weather/ip",//服务器URL
data : {ip:"124.126.230.180",key:"b2a208cb39cec1c93dd5534966708285"},//请求数据
success : function(datas){//datas是返回的JSON数据

if (datas.resultcode == 200) {//根据返回的数据 判断是否成功获取到JSON中的值
$("#city").text(datas.result.today.city);//解析数据到HTML文档中显示数据
$("#date").text(datas.result.sk.time+"发布");
$("#temp").text(datas.result.sk.temp+"°");
$("#weather").text(datas.result.today.weather);
$("#jt-tq").text(datas.result.today.weather);
$("#jt-wd").text(datas.result.today.temperature);
$("#jt-fx").text(datas.result.today.wind);
$("#two-week").text(datas.result.future.day_20161013.week);
$("#two-tq").text(datas.result.future.day_20161013.weather);
$("#two-wd").text(datas.result.future.day_20161013.temperature);
$("#two-fx").text(datas.result.future.day_20161013.wind);
$("#three-week").text(datas.result.future.day_20161014.week);
$("#three-tq").text(datas.result.future.day_20161014.weather);
$("#three-wd").text(datas.result.future.day_20161014.temperature);
$("#three-fx").text(datas.result.future.day_20161014.wind);

}else{

//错误...

}

}
});
});
