Convert string to time JavaScript (h:m)

Question

My friend and I are doing a school project; the task is to make a room-reservation-site. This is our first year trying JavaScript, and we want a string to be formatted into

Answer 1

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 and day values you might want to fetch for yourselves by checking the current date. This is purely to show how to convert the string into a date.

Use reserv.getTime() to convert to milliseconds time and thus being able to compare two times;

reserv.getTime() - reserv2.getTime()

For more information, check the MDN.

Answer 2

Yes. Use regular expressions and the Date object.

RegExps would be used to extract hours and minutes from the date string,

and the Date object would be used for comparisons.
