jquery - Convert string to time JavaScript (h:m) -


my friend , doing school project; task make room-reservation-site. our first year trying javascript, , want string formatted time (h:m). user of our room-reservation-site can choose time of day he/she wants room, , output is: h:m (24hour-clock:minutes). example 12:15.

therefor question is: there possible convert string (h:m) time, , check if user typed more 30minutes of booking-time? can example say:

 if(start_of_reservation < start_of_reservation(+30minutes)){     alert("you need book room atleast 30minutes"); }   else if(start_of_reservation > start_of_reservation(+6hours)){     alert("you can't book room longer 6 hours"); }   else {  // moving on..  } 

var year = '2013'; var month = '04'; var day = '18';  var hour = '12'; var min = '35';  var reserv = new date(year,month,day,hour,min)  console.log(reserv);

those year, month , day values might want fetch yourselves checking current date. purely show how convert string date.

use reserv.gettime() convert milliseconds time , being able compare 2 times;

reserv.gettime() - reserv2.gettime()

for more information, check mdn.
