【问题描述】：
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：

"results": [
{
"rsvp_limit": 90,
"status": "upcoming",
"visibility": "public",
"maybe_rsvp_count": 0,

同样，抓取 item.status 或 item.name 或 item.group.name 都可以正常工作，但一旦尝试抓取 item.venue.zip，我就会在控制台中收到类似这样的错误：
未捕获的类型错误：无法读取未定义的属性“zip”
什么给了？
【问题讨论】：
-
您发布的 JSON 是您从 API 收到的实际响应吗？
-
是的，这是我从 Meetup API 获得的实际响应的一部分。
-
看起来 JSON 搞砸了。 “结果”以数组开头，但以 } 结尾。当我遇到这样的问题时，它有助于控制台在 Firefox/Chrome 中记录响应，它将允许您遍历对象/数组。
-
哦，呃……那是因为我在某个时候把它剪掉了。让我编辑帖子以减少选择。
-
@Trendy 你能解释一下如何在 Firefox/Chrome 中控制台记录响应吗？例如，console.log(item.name) 不起作用。
