Question

I have some problem with IE (all versions). It don’t calculating the code of timestamp. My code is below:

function compute() {
    var c = $('select#time_from_hour').val();
    var d = $('select#time_from_minute').val();
    var e = $('select#time_to_hour').val();
    var f = $('select#time_to_minute').val();
    var g = $('input#date_from').val();
    var h = $('input#date_to').val();
    var hour1 = g + ' ' + c + ':' + d; 
    var hour2 = h + ' ' + e + ':' + f; 

    hour1 = hour1.split("/"); 
    var hour1 = hour1[1] + "," + hour1[0] + "," + hour1[2];
    var timestamp = (new Date(hour1).getTime() / 1000) + 7200;
    $('#total_hour1').val(timestamp);

    hour2 = hour2.split("/"); 
    var hour2 = hour2[1] + "," + hour2[0] + "," + hour2[2];
    var timestamp = (new Date(hour2).getTime() / 1000) + 7200;
    $('#total_hour2').val(timestamp);

    var x = -$('input#total_hour1').val();
    var y = -$('input#total_hour2').val();
    var total_time = x - y; 
    result = total_time / 86400;
    new_number = Math.ceil(result); 

    if (isNaN(new_number)) { 
        var new_number = 0;
    }

    $('#finish_day').val(new_number);
}

$('select#time_from_hour').change(compute);
$('select#time_from_minute').change(compute);
$('select#time_to_hour').change(compute);
$('select#time_to_minute').change(compute);
// $('select#return_car').change(compute);
$('select#get_car').change(compute);
$('input#finish_day').change(compute);

On other modern browser (firefox, opera, chrome) everything works fine. Only on IE i got the “NaN” value in timestamp1 and timestamp2.

Thanks in advice.

You seem to pass the Argument of the Date-Constructor in the wrong format. According to MSDN, the IE-Implementation of Date accepts the Date in the following order:

function Date( year : int, month : int, date : int[, hours : int [, minutes : int [, seconds : int [, ms : int]]]] )

If you make sure, that you pass the arguments in this format, everything should work fine. You’ll find the working Code here:
