JavaScriptとURLリクエストを使用して、JSONオブジェクトから現在の天気に関する情報を取得して表示しようとしています。

データを取得し、ビットを取り出してdivに表示するために、いくつかのスクリプトを試しました。最初のものは次のようになります。
$.ajax({
url: "http://free.worldweatheronline.com/feed/weather.ashx?q=de39ga&format=json&num_of_days=2&key=ec9c2dc5ba201904120805"
dataType: 'json',
success: function(data) {
jQuery.each(data, function() {
alert("HELLO");
alert("Current Cloud Cover = " + this.data.current_condition.cloudcover);
alert("Current Humidity = " + this.data.current_condition.humidity);
});
}
});
2番目のものは次のようになります。
var postcode = document.getElementById("address").value;
function getWeather(userName, count) {
$.getJSON(
'http://free.worldweatheronline.com/feed/weather.ashx?q' + postcode + '&format=json&num_of_days=2&key=ec9c2dc5ba201904120805',
{},
showWeather,
//'jsonp'
);
}
function showWeather(day) {
var str = '<ul>';
str += '<h2>Tweets from ' + postcode + '</h2>';
var i = 0;
$.each(day, function(index, value) {
if (i == count) return;
var dt = new Date(value.date);
str += '<p>';
str += value.temp_C; //gets "text" from JSON
str += '</p>';
str += '';
str += '';
i++;
});
}
JSON URLから天気情報を取得し、その情報の一部をdivに表示したいのですが、これを行う方法を誰かが説明できますか。これら2つのスクリプトは機能しません。
