Javascript calculation time difference function written by myself_javascript skills

I wrote it myself, it’s just applicable, not very good, it should still be optimized. Record it yourself first. Stop talking nonsense, it’s best to post the code directly:

Copy the code The code is as follows:

/ *
* Get the time difference, the time format is year-month-day hour:minute:second or year/month/day hour:minute:second
* Among them, year, month and day are in full format, for example: 2010-10 -12 01:00:00
* The return precision is: seconds, minutes, hours, days
*/
function GetDateDiff(startTime, endTime, diffType)
{
//Replace xxxx -xx-xx time format, converted to xxxx/xx/xx format
startTime = startTime.replace(/-/g, "/");
endTime = endTime.replace(/-/g, "/");

//Convert calculated interval characters to lowercase
diffType = diffType.toLowerCase();

var sTime = new Date(startTime); //Start time
var eTime = new Date(endTime); //End time

//Number as divisor
var divNum = 1;
switch (diffType)
{
case "second":
divNum = 1000;
break;
case "minute":
divNum = 1000 * 60;
         break;
      case "hour":
        divNum = 1000 * 3600;                   divNum = 1000 * 3600 * 24;
break ;
default:
break;
}
return parseInt((eTime.getTime() - sTime.getTime()) / parseInt(divNum));
}


The calling method is also very simple:
GetDateDiff("2010-10-11 00:00:00", "2010-10-11 00:01:40", "day")

This is Calculate the number of days
GetDateDiff("2010-10-11 00:00:00", "2010-10-11 00:01:40", "seond") is the calculation of the number of seconds
