Meetup API を使用しています。JSONからitem.venue.zipまたはitem.venue.address_1から値を取得できないことを除いて、すべてが機能しているようです。
これは私のコードです:
$(document).ready(function(){
$.getJSON("http://api.meetup.com/2/open_events.json?zip=10001&radius=7&topic=technology&status=upcoming&time=,1w&key=APIKEY&callback=?", function (data) {
var htmlString = "";
$.each(data.results, function (i, item) {
htmlString += '<h3><a href="' + item.event_url + '" target="_blank">' + item.name + '</a></h3>' + 'People attending: ' + item.yes_rsvp_count + item.time + item.group.name + item.maybe_rsvp_count; });
$('#upcoming').html(htmlString);
});
});
これは私のJSONがどのように見えるかです:

繰り返しますが、item.status、item.name、item.group.name のグラブはすべて正常に機能しますが、item.venue.zip をグラブしようとするとすぐに、コンソールに次のようなエラーが表示されます。
キャッチされていない TypeError: 未定義のプロパティ 'zip' を読み取れません
