 $.get("http://wthrcdn.etouch.cn/WeatherApi", { citykey: cityCode }, function (d) {
            //创建文档对象
            var parser = new DOMParser();
            var xmlDoc = parser.parseFromString(d, "text/xml");
            var cityList = xmlDoc.getElementsByTagName('city');
            var city = $(cityList[0]).text();
            var weatherList = xmlDoc.getElementsByTagName('weather');
            var $weather = $(weatherList[0]);
            var date = $weather.children("date").text();//时间
            var high = $weather.find("high").text();//最高气温
            var low = $weather.find("low").text();//最低气温
            var dayType = $weather.find("day type").text();//白天天气
