i'm not sure trying below best guess solution problem. incorporates .foreach loop loop through each day's forecast in response , retains way you've been parsing fields.

bug here: json.stringfy(field) -> json.stringify(field)
updated code loops:
$.getjson(search_url2, function (result) { $.each(result,function(i,field){ $("#forecast").append(json.stringify(field)); }); result.list.foreach(function(forecast, i) { $("#forecast").append("</br><b>" + + " " + result.list.length +" " + " </b>"); $("#forecast").append("</br>temperature @ day :" + forecast.temp.day); $("#forecast").append("</br>temperature @ morning :" + forecast.temp.morn); $("#forecast").append("</br>temperature @ evening :" + forecast.temp.eve); $("#forecast").append("</br>temperature @ night :" + forecast.temp.night); $("#forecast").append("</br>max temperature:" + forecast.temp.max); $("#forecast").append("</br>min temperature:" + forecast.temp.min); $("#forecast").append("</br>humidity: " + forecast.humidity + "%"); forecast.weather.foreach(function(weather) { $("#forecast").append("</br>weather condition : " + weather.description); }); $("#forecast").append("</p></div>"); $("#forecast").append("</br>temperature :" + forecast.temp.day); $("#result").append("</br>humidity :"+ forecast.main.humidity); $("#result").append("</br>weather condition :"+forecast.weather[0].description) ; }); });
