javascript - Match a pattern with a string and extract information -

-

i working on google apps script. want user enter pattern mm/dd/yyyy hh:mm:ss

according pattern want extract information string. string 02/29/2016 07:00:00 pm est. want extract date, month, year, hour, minute , second time-stamp string using pattern given user.

how can achieved in javascript ?

you can try example (in google apps script):

var = extractdatetimeinfo('mm/dd/yyyy hh:mm:ss', '02/29/2016 07:10:14 pm est'); logger.log(a);  //output: year: 2016, month: 02, date: 29, hours: 07, min: 10, sec: 14  var b = extractdatetimeinfo('yyyy-mm-dd hh:mm', '2016-12-26 16:13 pm est'); logger.log(b);  //output: year: 2016, month: 12, date: 26, hours: 16, min: 13, sec:    function extractdatetimeinfo(patt, t) {   var yyyypos = patt.indexof('yyyy');   var mmpos = patt.indexof('mm');   var ddpos = patt.indexof('dd');   var hhpos = patt.indexof('hh');   var mmpos = patt.indexof('mm');   var sspos = patt.indexof('ss');    var yyyy = yyyypos >= 0 ? t.substr(yyyypos, 4) : '';   var mm = mmpos >= 0 ? t.substr(mmpos, 2) : '';   var dd = ddpos >= 0 ? t.substr(ddpos, 2) : '';   var hh = hhpos >= 0 ? t.substr(hhpos, 2) : '';   var mm = mmpos >= 0 ? t.substr(mmpos, 2) : '';   var ss = sspos >= 0 ? t.substr(sspos, 2) : '';   return utilities.formatstring("year: %s, month: %s, date: %s, hours: %s, min: %s, sec: %s", yyyy, mm, dd, hh, mm, ss); }

however don't know type of pattern given user expect. can adapt other possibilities yy etc.

you can put result array in extractdatetimeinfo function well...
