我正在使用 Meetup API。一切似乎都有效，除了我无法从 JSON 中获取 item.venue.zip 或 item.venue.address_1 的值。
这是我的代码：
$(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);
});
});
这就是我的 JSON 的样子：

同样，抓取 item.status 或 item.name 或 item.group.name 都可以正常工作，但是一旦尝试抓取 item.venue.zip，我就会在控制台中收到如下错误：
未捕获的类型错误：无法读取未定义的属性“zip”
是什么赋予了？
