IE and Date Difference Javascript

[Pico_Train]

Hi there,

The code below works fine in Firefox. In IE it gives me a NAN value when I alert newcheckin or newcheckout.

Anybody know why?

Thanks for your help!

function dayDiff()
{
var checkin = document.getElementById('CHECK_IN').value;

var checkout = document.getElementById('CHECK_OUT').value;

var arrival = checkin.split("-");

var departure = checkout.split("-");

var newcheckin = new Date(arrival[2]+","+arrival+","+arrival[0]);

var newcheckout = new Date(departure[2]+","+departure[1]+","+departure[0]);

var one_day=1000*60*60*24;

if(newcheckin !="NaN" && newcheckout !="NaN")

//Assigning the Difference in days to the control

var diff = Math.ceil((newcheckin-newcheckout)/(one_day)) * -1;

return diff;

}

Function above isn't displaying correctly...use this instead

function dayDiff()
{
var checkin = document.getElementById('CHECK_IN').value;

var checkout = document.getElementById('CHECK_OUT').value;

var arrival = checkin.split("-");

var departure = checkout.split("-");

var newcheckin = new Date(arrival[2]+","+arrival[1]+","+arrival[0]);

var newcheckout = new Date(departure[2]+","+departure[1]+","+departure[0]);

var one_day=1000*60*60*24;

if(newcheckin !="NaN" && newcheckout !="NaN")

//Assigning the Difference in days to the control

var diff = Math.ceil((newcheckin-newcheckout)/(one_day)) * -1;

return diff;

}

In the following lines;

var newcheckin = new Date(arrival[2]+","+arrival[1]+","+arrival[0]);

var newcheckout = new Date(departure[2]+","+departure[1]+","+departure[0]);

You don't need to concatenate the comas;

var newcheckin = new Date(arrival[2],arrival[1],arrival[0]);

var newcheckout = new Date(departure[2],departure[1],departure[0]);

That should work fine assuming the values in CHECK_IN and CHECK_OUT are correct.

Perfect! Thanks for the advice!
