Hi...

Can anyone tell me how to program the following problem?

E.g
1st time: 1:00  PM
2nd time: 11:00 AM

The 2nd time is not supposed to be less than 1:00PM. How to compare the times and validate to ensure that the 1st time is before the 2nd time?

Hoping to hear from u soon....

Thanks,
StrawBerry

parse out the : and compare the num :

function compareTime(time1,time2)
{
var iTime1=parseInt(time1.split(":").join(""));
var iTime2=parseInt(time2.split(":").join(""));
if (iTime1>iTime2) alert('error !!!');


}

Use this:

if (dateA.getTime() > dateB.getTaime()){
 alert("A > B");
}

N.B. If dateA & dateB aren't date object, make it date with:

var dateA = new Date("01/01/2000 01:00 PM");
var dateB = new Date("01/01/2000 11:00 AM");

Dear guys,
