调用天气Api实现天气查询

 

上面是简单截图:

前台代码:

    Layout = null;
}

<!DOCTYPE html>

        }      
    </style>
</head>
<body>
    <input type="button" value="点击查看天气情况" id="btn1"/>
    <div id="dvShow">
        
    </div>
</body>
</html>
<script src="~/Content/jquery.min.js"></script>
<script>
    $(function () {
        $("#btn1").click(function () {
        $.getJSON('@Url.Action("Index2", "Home")',null,function(_data){
            var recwhether = _data.whether;
            var recindexdata = _data.indexdata;            
            for (var i = 0; i < recwhether.length; i++) {
                $("<p>" + recwhether[i].date + "</p><p><img src=" + recwhether[i].dayPictureUrl + "/></p><p><img src=" + recwhether[i].nightPictureUrl + "/></p><p>" + recwhether[i].weather + "</p><p>" + recwhether[i].wind + "</p><p>" + recwhether[i].temperature + "</p><p>" + recindexdata[i].title + "</p><p>" + recindexdata[i].zs + "</p><p>" + recindexdata[i].tipt + "</p><p>" + recindexdata[i].des + "</p><hr/>").appendTo("#dvShow");
            }
        });

        });
    });
</script>
