通过mongo shell将Date（）插入Mongodb

问题描述

我通过以下查询插入文档：

I am inserting document through following query:

db.collection.insert(
{
      date: Date('Dec 12, 2014 14:12:00')
})

但它会给我一个错误。

But it will give me an error.

如何在不收到错误的情况下在我的收藏中插入日期？

How can I insert a date in my collection without getting an error?

推荐答案

你必须得到一个不同的错误，因为上面的代码将导致 Date（）方法返回当前日期作为字符串，无论提供的参数如何物体。来自： JavaScript日期只能通过调用JavaScript Date 作为构造函数来实例化对象：将其作为常规函数调用（即没有 new operator）将返回一个字符串而不是 Date 对象;与其他JavaScript对象类型不同，JavaScript Date对象没有文字语法。

You must be getting a different error as the code above will result in the Date() method returning the current date as a string, regardless of the arguments supplied with the object. From the documentation: JavaScript Date objects can only be instantiated by calling JavaScript Date as a constructor: calling it as a regular function (i.e. without the new operator) will return a string rather than a Date object; unlike other JavaScript object types, JavaScript Date objects have no literal syntax.

您可能想尝试这样做以获得正确的日期，请记住JavaScript的Date构造函数的month参数是从0开始的：

You might want to try this instead to get the correct date, bearing in mind that the month parameter of JavaScript's Date constructor is 0-based:

var myDate = new Date(2014, 11, 12, 14, 12);
db.collection.insert({ "date": myDate });
