How to check if input date is equal to today's date?

Question

I have a form input with an id of \'date_trans\'. The format for that date input (which is validated server side) can be any of:

• dd/mm/yyyy
• dd-mm-yyyy

Answer 1

The following solution compares the timestamp integer divided by the values of hours, minutes, seconds, millis.

var reducedToDay = function(date){return ~~(date.getTime()/(1000*60*60*24));};
return reducedToDay(date1) == reducedToDay(date2)

The tilde truncs the division result (see this article about integer division)
