JS Time Difference

VaR date1 = new date (); // start time Alert ("AA"); var date2 = new date (); // End Time var date3 = date2.gettime () -date1.gettime () // time difference in milliseconds

// Calculate the number of different days var days = math. Floor (date3/(24*3600*1000 ))

// Calculate the number of hours

VaR leave1 = date3 % (24*3600*1000) // The number of milliseconds remaining after the computing day var hours = math. floor (leave1/(3600*1000) // calculate the number of different minutes var leave2 = leave1 % (3600*1000) // The number of milliseconds remaining after the computing hours var minutes = math. floor (leave2/(60*1000 ))

// Calculate the difference in seconds var leave3 = leave2 % (60*1000) // calculate the remaining milliseconds after the number of minutes var seconds = math. Round (leave3/1000)

Alert ("difference" + days + "days" + hours + "hours" + minutes + "Minutes" + seconds + "seconds ")
