Parsing a string to a date in JavaScript (35 answers)
Closed 5 years ago.
I have a date string like 2019-06-12 12:02:12 232 ,how to convert to date using Javascript?
Date date = Date.parse( 2019-06-12 12:02:12 232 ).format( yyyy-MM-dd dd:HH:ss SSS );
I want to compare two date to calculate the minisecond in Javascript.Any suggestion?How could I tweak my date string?The date string was generate is server side using Java:
DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss SSS");
String dateTime = LocalDateTime.now(ZoneOffset.of("+8")).format(formatter);
This question does not contain minisecond,if no minisecond,Date.parse could solved the problem.My question is precise contain more detail operation of Javascript Date.

You can do it like that:
const dateString = "2019-06-12 12:02:12 232"
const [y,M,d,h,m,s] = dateString.split(/[- :]/);
const yourDate = new Date(y,parseInt(M)-1,d,h,parseInt(m),s);
console.log(`yourDate ${yourDate}`);
In addition, avoid using Date.parse() method.
UPDATE:
By using the above approach, you will avoid some strange bugs as described in the above link. However, it is possible to use a great library Moment.js:
moment("12-25-1995", "MM-DD-YYYY");
Moreover, you could check if a date is valid:
moment("whether this date is valid").isValid(); // OUTPUT: false
