JavaScript function sharing _javascript techniques for calculating time lag

Copy code code as follows:

/*
* Get time difference, the date format is year-month-day hour: minutes: seconds or Year/month/day hours: minutes: seconds
* in which, the date of year is full format, for example: 2010-10-12 01:00:00
* Return precision: seconds, minutes, hours, days
*/
function Getdatediff (StartTime, Endtime, Difftype) {
Converts the XXXX-XX-XX time format to the XXXX/XX/XX format
StartTime = Starttime.replace (/\-/g, "/");
Endtime = Endtime.replace (/\-/g, "/");
Converts the calculated interval class character to lowercase
Difftype = Difftype.tolowercase ();
var stime = new Date (starttime); Start time
var etime = new Date (endtime); End time
As a divisor of the number
var divnum = 1;
Switch (difftype) {
Case "Second":
Divnum = 1000;
Break
Case "Minute":
Divnum = 1000 * 60;
Break
Case "Hour":
divnum = 1000 * 3600;
Break
Case ' Day ':
divnum = 1000 * 3600 * 24;
Break
Default
Break
}
Return parseint (Etime.gettime ()-stime.gettime ())/parseint (divnum));
}

Calling a method is also simple:
Getdatediff ("2010-10-11 00:00:00", "2010-10-11 00:01:40", "Day")
This is the count of days
Getdatediff ("2010-10-11 00:00:00", "2010-10-11 00:01:40", "Seond") is the count of seconds
