Create an ISO date object in javascript

Question

I have a mongo database set up. creating a new date object in mongoDb create a date object in ISO format eg: ISODate("2012-07-14T00:00:00Z")

I am using node.js to connect to mongo database and query the database. when ever I create a new date object (new Date()) in javascript its creates a javascript date object eg: Wed Mar 06 2013 14:49:51 GMT-0600 (CST)

Is there a way to create an ISO date object in javascript so that I can send the object directly to the mongoDb and perform date query

I am able to perform the below query in mongoDb

db.schedule_collection.find({
  start_date: { '$gte': new Date(2012, 01, 03, 8, 30) }
})

but cannot perform when I send in an javascript date object from node

The mongodb cookbook provides an python example to query the mongo database using datetime module, but does not provide any example use javascript.

Any help is appreciated. Thanking you in advance

Solution 1

Try using the ISO string

var isodate = new Date().toISOString()

See also: method definition at MDN.

Solution 2

try below:

var temp_datetime_obj = new Date();

collection.find({
    start_date:{
        $gte: new Date(temp_datetime_obj.toISOString())
    }
}).toArray(function(err, items) { 
    /* you can console.log here */ 
});

Solution 3

In node, the Mongo driver will give you an ISO string, not the object. (ex: Mon Nov 24 2014 01:30:34 GMT-0800 (PST)) So, simply convert it to a js Date by: new Date(ISOString);

Solution 4

This worked for me:

var start = new Date("2020-10-15T00:00:00.000+0000");
 //or
start = new date("2020-10-15T00:00:00.000Z");

collection.find({
    start_date:{
        $gte: start
    }
})...etc

new Date(2020,9,15,0,0,0,0) may lead to wrong date: i mean non ISO format (remember javascript count months from 0 to 11 so it's 9 for october)

Solution 5

I solved this problem instantiating a new Date object in node.js:...

In Javascript, send the Date().toISOString() to nodejs:...

var start_date = new Date(2012, 01, 03, 8, 30);

$.ajax({
    type: 'POST',
    data: { start_date: start_date.toISOString() },
    url: '/queryScheduleCollection',
    dataType: 'JSON'
}).done(function( response ) { ... });

Then use the ISOString to create a new Date object in nodejs:..

exports.queryScheduleCollection = function(db){
    return function(req, res){

        var start_date = new Date(req.body.start_date);

        db.collection('schedule_collection').find(
            { start_date: { $gte: start_date } }
        ).toArray( function (err,d){
            ...
            res.json(d)
        })
    }
};

Note: I'm using Express and Mongoskin.

Mongodb driver only works with the date object. I must admit that the question is a bit unclear. The following answer solved my problem: stackoverflow.com/questions/21286599/…

a string is not an object so I'm guessing the object we want is just the new Date('...') object. So basically ISODate(..) is the same as new Date(..)?

After 3 hours long search, I found this solution. No moment Js, No ISO conversion, Nothing.

I found that using this method, the date is a date string instead of ISODate object. What I mean is that: [var isodate = new Date().toISOString()] => ["time" : "2018-03-08T08:15:15.919Z"] While [var isodate = new Date(new Date().toISOString())] => ["time" : ISODate("2018-03-08T08:15:16.097Z") ]

^^ Thanks, mongodb is expecting Date Object.

[Mark Odey]

This casted the input as string. Now I can't perform aggregate with this field.

Works! Wrapping the toISOString() output in new Date() did it.
