Question

我正在使用Meetup API。一切似乎都有效，除了我无法从JSON中的item.venue.zip或item.venue.address_1中获取值。

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,
        "venue": {

})

再一次，抓住item.status或item.name或item.group.name都可以正常工作，但是一旦尝试抓住item.venue.zip，我就会在控制台中收到这样的错误：

未捕获的TypeError：无法读取未定义的属性“zip”

是什么给出了？

Answer 1

更新：我发现所有数据项都没有“场地”属性（即数据不完整），所以我不得不申请

 if (item.venue)

代码。

另外，我下载了一个chrome扩展程序，当我在浏览器中查看JSON文件时，它有助于更好地解析JSON。

从Meetup API中获取此JSON文件中的某些值不起作用
