How to parse jqwidgets (jqx) date with format?

Basically I have date format which comes from server and which will be not known before and a date that was already formatted in this format, e.g. the format is "dd/MM/yyyy" and the date is "21/01/2018" (two strings). The format that uses jqx differs from the default JS one, as I can see.
What I need to do is to parse it to JavaScript date object. I couldn't find the answer in the official documentation.
Is there any easy was of parsing the date string if you know the date format, using JS, jqwidgets or momentjs?

Eventually, I've finished with inner jqx method that does that exact thing:
var parsedDate = $.jqx.dataFormat.parsedate(src, format);
Where format in this case is "dd/MM/yyyy" and src is "21/01/2018".
P.S. Thanks for the guy that posted anwer with the code that used $.jqx.dataFormat, that really helped me to find parsedate method.

Working with date formats in Java and MySQL

Ok this is really bugging me.
I am developing a web app and I need to work with dates. When a date is displayed in a view, or whenever a date is entered into a form I need the format to be dd/mm/yyyy.
What data type do I choose for my SQL database columns which contain dates. 'Date' doesn't seem to work, do I use varchar?
But If I use varchar how do I use java script to perform arithmetic with dates.
Do I do some conversions server-side?
Please advise the best practices.
Also Im using laravel if theres any useful stuff already built in.

Date is the correct type to use in SQL DB.
To access the value use ISO date format "YYYY-MM-DD HH:mm:ss" .
You can create it from Java Date Object by using toISOString() method.
For easier time format conversion I can also recommend to check out Moment.js.

Best practice to save the date in MySQL table as date field only. Which saves the date string in YYYY-MM-DD HH:mm:ss format.
You need to make sure the following things.
Before inserting date into MySQL change the format of date string to YYYY-MM-DD HH:mm:ss.
When you retrieve the date from database convert the date string from YYYY-MM-DD HH:mm:ss to your desired format.
You can use SimpleDateFormat class in Java to convert the dates
format. Use format() function to format the date in desired and
parse() function to get the Java date object from string.
Reference: https://docs.oracle.com/javase/7/docs/api/java/text/SimpleDateFormat.html

You should use varchar2 in mysql.
You can retrieve that varchar type date in javascript and create date object.
var d=dbdate;
var date = new Date(d);
And you can perform all javascript functions on date.
Hope it will help.

Javascript Date() object supports separate entries of date by:
var date=new Date();
var y=date.getFullYear();//4 digits
var m=date.getMonth()+1;//0-11 digits, plus 1 for true state
var d=date.getDate();//1-31
var dateSQL=y+'-'+m+'-'+d;//i.e 2016-07-25

you can use MySQL filed as datetime and also insert datetime format but when you will show then process it as you want as like
when you insert value in table then you can also format it as like
<?php $mysqltime = date ("Y-m-d H:i:s", $phptime); ?>
where $phptime is your input variable
$str = suppose $row['date'] (mysql filed value)
date("d/m/Y", strtotime($str));
where $str your retrieve date filed

JavaScript: Get date format from culture settings

I want to get Date format from my defined culture settings using JavaScript.
My Culture is defined in Web.config File as:
<globalization culture="en-GB" uiCulture="en-GB"/>
I am getting the defined Culture through
CultureInfo culture = System.Globalization.CultureInfo.CurrentUICulture;
and i am passing it to my client. And at Client side I am using momemt.js library to parse my json date in to actual date format.
var date = moment(JsonDate).toDate().toLocaleDateString(myCulture); //"en-GB"
and I am getting the date in the required date format as "16/07/2016"
but I also want to get this Format as dd/MM/yyyy so that I can use this culture date format in my html (for date picker).
Please let me know how can I get this date format using culture info at client side.

You can use AngularJS-s date filter
check this link please - https://docs.angularjs.org/api/ng/filter/date

You may install moment.js in your project. https://momentjs.com/
Include moment-with-locales.min.js in your HTML template.
In your JavaScript:
moment.locale(myCulture);
var date = moment(JsonDate).format('L')

Compare ISO date without time stamp in javascript

I am querying data using OData, url looks like http://myurl.com/api/Customer?$filter=ResDate eq DateTime'2014-03-15T12:01:55.123'.
I'm getting date/time from jquery.datepicker instead of the static date and using moment.js to convert from DD-MM-YYYY to YYYY-MM-DDTHH:mm:ss in order to pass it to web service.
function convertDateToISOdate(date){
var newDate = moment(date,'DD-MM-YYYY').format('YYYY-MM-DDTHH:mm:ss');
return newDate;
}
Date returns from the function, is 2014-03-15T00:00:00.
Problem : 2014-03-15T12:01:55.123 is not equal to 2014-03-15T00:00:00, so there's no record selected.
What I want is , just to compare the date , not include time stamp.
Note : I can not change the format date/time at server side(Web service) because it's not belongs to me.
Any idea is much appreciated.

Your first call to moment(date,'DD-M-YYYY') is stripping the time information from the incoming data. try using moment(date) (no format) instead because momentjs recognizes your incoming date format intrinsically, without having to be told which format to use, and will correctly parse the H:M:S data, too.

JavaScript moment format date string

I am using the Moment JavaScript library to take a date from my jQuery UI date picker. The date picker is currently using a format of mm/dd/YYYY in order to display a value to a user, so today would show as: 12/17/2013. I need to submit this date in an XHR request using the format YYYYmmdd so the example above would turn into 20131217. I tried using Moment like this:
var t_date = moment($("#datepicker").attr('value').replace('/', '-'), "MM-DD-YYYY");
The result for t_date however, comes out to be a large double, almost like a unix timestamp. At that point, I'm not entirely sure how to have Moment convert it to the string result I need above so I can embed it into a RESTful URL for my XHR request.

you can use the format function:
var t_date = moment($("#datepicker").attr('value').replace('/', '-'),'MM-DD-YYYY')
.format('YYYYMMDD');
