js动态获取当前城市天气参数

该demo使用的是angular.js框架

一、天气接口：http://wthrcdn.etouch.cn/weather_mini?city=城市名称

二、js中调用

　　 /*获取天气参数*/
    function refreshWeather() {
        jQuery.support.cors = true;
        var url = encodeURI("http://wthrcdn.etouch.cn/weather_mini?city=" + $scope.city);
        $.get({
            url: url,
            dataType: "json",
            async: false,
            success: function (data) {
                var list = data.data.forecast;
                if (list.length < 3) {
                    return;
                }
                var wList = [];
                for (var i = 0; i < 3; i++) {
                    var item = list[i];
                    var high = item.high.split(" ")[1];
                    var low = item.low.split(" ")[1];
                    wList.push({
                        day: item.date.slice(-3),
                        type: item.type,
                        temperature: high + "/" + low
                    });
                }
                $scope.$apply(function () {
                    $scope.weatherList = wList;
                });
            }
        });
    }
　　

/*获取当前时间*/
function refreshDate() {
    var nowDate = new Date();
    var h = nowDate.getHours();
    $scope.$apply(function () {
        $scope.nowDate = zero(hours(h)) + "." + zero(nowDate.getMinutes());
        $scope.ampm = h < 12 ? "AM" : "PM";
    });

    function hours(value) {
        return value % 12;
    }

    function zero(str) {
        str = "" + str;
        if (str.length === 1) {
            str = "0" + str;
        }
        return str;
    }
}

/*获取本地城市地址--高德地图api*/
function refreshLocalCity(complete) {
    AMap.plugin('AMap.CitySearch', function () {
        new AMap.CitySearch().getLocalCity(function (status, result) {
            if (status === 'complete' && result.info === 'OK') {
                $scope.$apply(function () {
                    $scope.city = result.city;
                });
                complete && complete();
            }
        })
    });
}

三、html页面

<div class="item t2">
        <div class="item-con">
            <div class="title-div">
                <div class="time-title">{{nowDate}}</div>
                <div class="other-div">
                    <div id="address-title" class="address-title">{{city}}</div>
                    <div class="ampm-title">{{ampm}}</div>
                </div>
            </div>
            <div class="weather-div">
                <div class="w-item" ng-repeat="item in weatherList">
                    <div class="day">{{item.day}}</div>
                    <div class="type">{{item.type}}</div>
                    <div class="temperature">{{item.temperature}}</div>
                </div>
            </div>
        </div>
    </div>
<!-- 高德地图所需 -->

<script type="text/javascript" charset="utf-8" src="http://webapi.amap.com/maps?v=1.3&key=xxxxxx&plugin=AMap.Autocomplete,AMap.PlaceSearch"></script>
