Parse from String to DateTime

Question

I have a date in format YYYYMMDDTHHMMSS and need to get the date in format DD.MM.YYYY HH:MM:SS . I do such:

var dateTimeFormat;
var dateAsString = dataTimeFormat.split('', dateTimeFormat.lenght);
var year = dateAsString.splice(0, 4).join('');
var month = dateAsString.splice(0, 2).join('');
var day = dateAsString.splice(0, 2).join('');
var hours = dateAsString.splice(1, 2).join('');
var minutes = dateAsString.splice(1, 2).join('');
var seconds = dateAsString.splice(1, 2).join('');
var date = day + '.' + month + '.' + year + ' ' + hours + ':' + minutes + ':' + seconds;
return date;

But how can I convert date to Date format?

After transforming string into a known format, Date::parse() will be enough:

var yourDate = new Date(Date.parse(date));

WORKING DEMO:

var date = "2016.06.15 10:10:10";
var yourDate = new Date(Date.parse(date));
alert(yourDate);

NOTE: your format is a bit weird, but maybe parse will accept it as long as it accept many string formats such as:

Date.parse("Aug 9, 1995");
Date.parse("Wed, 09 Aug 1995 00:00:00");
Date.parse("Wed, 09 Aug 1995 00:00:00 GMT");

I think parse function is excessive, you can pass date string directly in new date.

Thanks, but I confused a bit. I need to show the date in a table and then sort by date. I did that script you adviced and I get this imgur.com/or3bTOa . I think I need to leave the date as string and then write sort function to compare separately years, months, dates, etc ?

IMHO is better to sort an array of Dates. Check this answer and this documentation

I used your code but not always the function returns 'Invalid Date {}' . What's wrong?

It happens because the string parsed is not correct date, check valid formats here

you are not converting to Date as OP demands, you only transform String format
