如何在mongoose中查询created今天（从00h：00m：00到现在）的所有数据？

{
  "user": ObjectId("52fe173148ee58a0180c1d77"),
  "caption": "aaaa",
  "created": ISODate("2014-02-14T16:04:57.98Z"),
  "__v": NumberInt(0)
}

{
  "user": ObjectId("52fe173148ee58a0180c1d77"),
  "caption": bbb",
  "created": ISODate("2014-02-14T14:10:27.986Z"),
  "__v": NumberInt(0)
}

Answer 1

只需创建一个包含今天开头的Date对象，然后在查询中使用该对象：

var now = new Date();
var startOfToday = new Date(now.getFullYear(), now.getMonth(), now.getDate());
MyModel.find({created_on: {$gte: startOfToday}}, function (err, docs) { ... });
