我将此代码放入我的应用程序中，以json格式返回一些作业提要：
我的代码如下所示：
JobFeed.find().sort('-created').exec(function (err, feeds) {
if (err) {
return res.status(400).send({
message: errorHandler.getErrorMessage(err)
});
} else {
_.forEach(feeds, function (row, key) {
console.log(row.data.title); // showing undefined
});
res.jsonp(feeds);
}
});
，json如下所示：

我拥有的foreach似乎遍历每个项目，但我无法获得每个项目的标题。任何帮助？
答案 0 :(得分：0)
我不确定你要做什么，但如果数据确实与你的评论相符，那么这样的事情应该有效：
feeds.forEach(function(feed){
console.log(feed.data.title);
});
如果您想要更快的性能，请使用常规for循环。我在我的项目中对此进行了测试。如果这不起作用，请告诉我。
