javascript date to string

Question

Here is what I need to do    Get Date  convert to string and pass it over to a third party utility   The response from the library will have date in string format as I passed it  So  I need to convert the date to string like 20110506105524  YYYYMMDDHHMMSS   function printDate         var temp   new Date        var dateStr   temp getFullYear   toString                        temp getMonth   toString                        temp getDate   toString                       temp getHours   toString                        temp getMinutes   toString                        temp getSeconds   toString         debug  dateStr        The problem with above is that for months 1-9  it prints one digit  How can I change it to print exactly 2 digits for month  date

I like Daniel Cerecedo s answer using toJSON   and regex  An even simpler form would be   var now   new Date    var regex       d 4  -  d 2  -  d 2  T  d 2     d 2     d 2        var token array   regex exec now toJSON           2017-10-31T02 24 45 868Z    2017    10    31    02    24    45    var myFormat   token array slice 1  join          20171031022445

You will need to pad with  0  if its a single digit  amp  note getMonth returns 0  11 not 1  12  function printDate         var temp   new Date        var dateStr   padStr temp getFullYear                        padStr 1   temp getMonth                        padStr temp getDate                        padStr temp getHours                        padStr temp getMinutes                        padStr temp getSeconds         debug  dateStr       function padStr i        return  i  lt  10     0    i        i

Maybe it is easier to convert the Date into the actual integer 20110506105524 and then convert this into a string   function printDate         var temp   new Date        var dateInt               temp getFullYear     100                temp getMonth     1    100               temp getDate      100             temp getHours      100             temp getMinutes      100            temp getSeconds         debug        dateInt        convert to String     When temp getFullYear    lt  1000 the result will be one  or more  digits shorter   Caution  this wont work with millisecond precision  i e  17 digits  since Number MAX SAFE INTEGER is 9007199254740991 which is only 16 digits

Relying on JQuery Datepicker  but it could be done easily   var mydate   new Date      datepicker formatDate  yy-mm-dd   mydate

A little bit simpler using regex and toJSON     var now   new Date    var timeRegex       T  d 2     d 2     d 2       var dateRegex       d 4  -  d 2  -  d 2  T     var dateData   dateRegex exec now toJSON     var timeData   timeRegex exec now toJSON     var myFormat   dateData 1  dateData 2  dateData 3  timeData 1  timeData 2  timeData 3    Which at the time of writing gives you  20151111180924    The good thing of using toJSON   is that everything comes already padded
