如何在javascript中迭代json数组

是的，关于这个问题有很多帖子。但是我的疑问有点不同。我有以下示例数组\n

var dictionary = {
    "12Jan2013": [{
        "id": "0",
        "name": "ABC"
    }, {
        "id": "1",
        "name": "DEF"
    }],
    "13Jan2013": [{
        "id": "0",
        "name": "PQR"
    }, {
        "id": "1",
        "name": "xyz"
    }]
};

\n在同一网站上有相同的帖子，但是在这个字典的json数组键是动态的。这里是日期，例如12Jan2013。它可以是任何日期。它不是静态的。我搜索了一下，但是没有找到解决方法。\n如何迭代这样一个json数组？\n以及如何按照上面显示的相同格式打印json数组？\n编辑\n这是我的真实代码。我在下面的代码中显示了一个注释，我希望在getWeatherDataForCities回调中迭代数据，即jsonData变量\n

var arrAllrecords = [];
var arrCityrecordForADay = [];
function getWeatherDataForCities(cityArray, callback){
var toDaysTimestamp = Math.round((new Date()).getTime() / 1000) - (24*60*60);
for(var i in cityArray){
    for(var j=1; j<=1; j++){
        var jsonurl = "http://api.openweathermap.org/data/2.5/history/city?q="+cityArray[i]+"&dt="+toDaysTimestamp;
        $.ajax({
            url: jsonurl,
            dataType: "jsonp",
            mimeType: "textPlain",
            crossDomain: true,
            contentType: "application/json; charset=utf-8",
            success: function(data){                    
                var arrCityRecordForDay = [];
                /*arrCityrecordForADay.push(data.list[0].city.name);
                arrCityrecordForADay.push(data.list[0].weather[0].description);
                arrCityrecordForADay.push(timeConverter(data.list[0].dt));
                arrCityrecordForADay.push(data.list[0].main.temp);
                arrCityrecordForADay.push(data.list[0].main.humidity);
                arrCityrecordForADay.push(data.list[0].main.pressure)
                arrCityrecordForADay.push(data.list[0].wind.speed);*/
                //'{"pets":[{"name":"jack"},{"name":"john"},{"name":"joe"}]}';
                arrCityRecordForDay.push(
                    {"cityName" : data.list[0].city.name},
                    {"weather" : data.list[0].weather[0].description}
                );
                var tempId = data.list[0].city.name+"-"+timeConverter(data.list[0].dt);
                arrCityrecordForADay.push(
                    {tempId : arrCityRecordForDay}
                );
                if(((arrCityrecordForADay.length)) === cityArray.length) {
                    callback(arrCityrecordForADay);
                }
        } });
        toDaysTimestamp = toDaysTimestamp - (24*60*60);
    }   
}       
}
$(document ).ready(function() {
 var cityArray = new Array();
  cityArray[0] = "pune";
  getWeatherDataForCities(cityArray, function(jsonData) {
        // 这里我想迭代jsonData
  });
});
