regular expressions challenge!

Copy linkTweet thisAlerts:

I’m trying to build a regular expression for Canadian postal codes for javascript but I’m not really up to the task. Can anyone here do it?

It needs to be:
letter (upper case only)
number
letter (upper case only)
no space OR space OR dash
number
letter (upper case only)
number
And then no more.

What would this regular expression look like?

@steelersfan88Jul 06.2004 — Maybe somehting like:<script type="text/javascript">

/* Requirements:
> letter (upper case only)
> number
> letter (upper case only)
> no space OR space OR dash
> number
> letter (upper case only)
> number
> And then no more.
*/

var test_str = "A2A-2A2"
var reg_exp = /[A-Z]d[A-Z](s?|-)d[A-Z]d$/

alert(reg_exp.test(test_str))

/* online examples:
1 >> /^([a-z]d){3}$/i
2 >> /^[a-cehj-npr-tvxy]d[a-z](s)?d[a-z]d$/i
*/

</script>Dr. Script
