Javascript 无法从以下json获取标题

我的应用程序中包含以下代码，该代码以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

，似乎迭代了每个项目，但我无法获得每个项目的标题。有什么帮助吗？

我不太确定你想做什么，但是如果你的评论中确实有数据，那么这样的方法应该可以奏效：

feeds.forEach(function(feed){
  console.log(feed.data.title);
});

---

如果想要更快的性能，请使用常规for循环。我在我的项目上测试了这个。如果这不起作用，请告诉我。

这不是JSON。。您可以获取原始JSON数据，如果没有，您可以

fs.writeFileSync（'somefile.JSON'，JSON.stringify（feed））

@Keith我仍然无法获取每个对象的标题。。。你知道还有其他方法吗？feeds对象就是这个样子吗？它看起来不像一个数组，而是四个独立的对象。运行JSON.stringify（feeds）时会显示什么？它使它看起来像这样：[{“\u id”：“57ffcd9e717ca50cf0b4cb61”，“数据”：{“反馈”：null，“粘贴标签”：“粘贴”：false，“子类别2”：“Web开发”，“持续时间”：“不到1个月”，“最大金额”：{“currencyCode”：“USD”，“amount”：0}，“自由职业者ToHire….它是这样工作的，我不知道为什么：var list=JSON.parse（JSON.stringify（feeds））；u.forEach（list，function（row，key）{console.log（row.data.title）；}）；
