response：var weatherinfovar = {"weatherinfo":{"city":"\u90d1\u5dde","cityid":"101180101","temp":"13","SD":"82%","WD":"\u4e1c\u5317\u98ce","WS":"1\u7ea7","QY":"1026","JS":"\u964d\u6c34\u6982\u7387: 59%","pm25":"22","idx":"39","lv_hint":"\u4f18","aqiLevel":1}};
解析後：weatherinfo:
JS: "降水概率: 59%"
QY: "1026"（氣壓）
SD: "82%" （溼度）
WD: "東北風"
WS: "1級"
aqiLevel: 1
city: "鄭州"
cityid: "101180101"
idx: "39"
lv_hint: "優"
pm25: "22"
temp: "13"（當前溫度）
__proto__: Object
