Use javascript to calculate the number of days between two dates

The difference between computing two time points in ASP can be DateDiff, but it does not exist in javascript and requires a handwritten function.
Js inside can be directly Date1-Date2, and still converted to millisecond time difference calculation.


Copy codeThe Code is as follows:
// Calculate the number of days between two dates
Function DateDiff (sDate1, sDate2) {// The format of sDate1 and sDate2 is 2002-12-18
Var aDate, oDate1, oDate2, iDays
ADate = sDate1.split ("-")
ODate1 = new Date (aDate [1] + '-' + aDate [2] + '-' + aDate [0]) // convert to the 12-18-2002 format
ADate = sDate2.split ("-")
ODate2 = new Date (aDate [1] + '-' + aDate [2] + '-' + aDate [0])
IDays = parseInt (Math. abs (oDate1-oDate2)/1000/60/60/24) // converts the number of milliseconds to the number of days
Return iDays
}
