Я видел другие связанные вопросы, но не смог найти точного соответствия моей проблеме на SO.Попытка вернуть JSON с worldweatheronline.com с помощью $ .ajax и постоянно получать пустой ответ.В Fiddler, однако, я вижу правильный ответ каждый раз, только в браузере, он кажется пустым (ищется с помощью Firebug и операторов alert).Используя метод .ajax, я хочу проанализировать JSON при наличии ответа.
Ниже приведен фрагмент кода, необработанный запрос и необработанный ответ.
var jsonxhr = $.ajax({
url: 'http://free.worldweatheronline.com/feed/weather.ashx?q=55122&format=json&num_of_days=5&key=<somekey>',
type: 'GET',
dataType: 'jsonp',
success: function (json) {
alert('request success');
},
error: function (xhr, status) {
alert('request error');
},
complete: function (xhr, status) {
//alert('request complete');
try {
var parsedJson = $.parseJSON(jsonxhr.responseText);
//alert('success parsing');
alert('test' + jsonxhr.responseText + 'test');
alert('headers ' + jsonxhr.getAllResponseHeaders());
//alert(parsedJson.data.weather.tempMaxF.toString());
}
catch (e) {
alert("error parsing");
}
}
});
