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 

{ "resultcode":"200", "reason":"successed!", "result":{ "sk":{ "temp":"21", "wind_direction":"东北风", "wind_strength":"3级", "humidity":"66%", "time":"14:00" }, "today":{ "temperature":"17℃~22℃", "weather":"阴", "weather_id":{ "fa":"02", "fb":"02" }, "wind":"东北风3-4 级", "week":"星期三", "city":"无锡", "date_y":"2016年10月12日", "dressing_index":"较舒适", "dressing_advice":"建议着薄外套、开衫牛仔衫裤等服装。年老体弱者应适当添加衣物，宜着夹克衫、薄毛衣等。", "uv_index":"最弱", "comfort_index":"", "wash_index":"较适宜", "travel_index":"较适宜", "exercise_index":"较适宜", "drying_index":"" }, "future":{ "day_20161012":{ "temperature":"17℃~22℃", "weather":"阴", "weather_id":{ "fa":"02", "fb":"02" }, "wind":"东北风3-4 级", "week":"星期三", "date":"20161012" }, "day_20161013":{ "temperature":"17℃~21℃", "weather":"阴", "weather_id":{ "fa":"02", "fb":"02" }, "wind":"东北风3-4 级", "week":"星期四", "date":"20161013" }, "day_20161014":{ "temperature":"18℃~22℃", "weather":"阵雨", "weather_id":{ "fa":"03", "fb":"03" }, "wind":"东北风3-4 级", "week":"星期五", "date":"20161014" }, "day_20161015":{ "temperature":"17℃~22℃", "weather":"阵雨", "weather_id":{ "fa":"03", "fb":"03" }, "wind":"东北风3-4 级", "week":"星期六", "date":"20161015" }, "day_20161016":{ "temperature":"17℃~24℃", "weather":"阴", "weather_id":{ "fa":"02", "fb":"02" }, "wind":"东北风3-4 级", "week":"星期日", "date":"20161016" }, "day_20161017":{ "temperature":"17℃~21℃", "weather":"阴", "weather_id":{ "fa":"02", "fb":"02" }, "wind":"东北风3-4 级", "week":"星期一", "date":"20161017" }, "day_20161018":{ "temperature":"17℃~21℃", "weather":"阴", "weather_id":{ "fa":"02", "fb":"02" }, "wind":"东北风3-4 级", "week":"星期二", "date":"20161018" } } }, "error_code":0 }

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...

}

}
});
});
