date problems in javascript[resolved]

[thebloke]

Hmm, here's a thing.

I have a date which is passed in a form (dd/mm/yyyy). I need to compare this to today's date using javascript.

<script language="javascript">
function somefunction()
{
var renewdate = document.frm.renewdate.value;
var today = new Date()

renewdte = Date.parse(renewdate)
todaysdte = Date.parse(today)
thedate = today.getDay();

if (renewdte < todaysdte)
{
alert("The date of your renewal has passed");
return false;
} 
}
</script>

Now, this works on my development machine but not on my live web server. I have

<%setLocale(2057)%>

In the page that contains the form but the live web server is taking the renewal date 01/10/2005 in the US format 10/01/2005.

And it's proper doing my head in!

Any clues?

Something has occurred to me. I think if I could coerce the form field 'renewdate' into a javascript Date object then I should be able to manipulate it that way but I've tried:

var day = renewdate.substr(0,2)
var month = renewdate.substr(3,2)
var year = renewdate.substr(6,4)

var whenever = new Date(year,month,day)

alert(whenever);

But this returns:

Tue Nov......oh, hang on! I've cracked it!

Hooray (runs round office, arms aloft....like a loser)....
