Byte saving, string manipulation

I'm 65 bytes off of the 508 byte limit for a bookmarklet to work in IE. I'm looking to extract the TLD of the current page (whatever.com, whatever.org, ...). I currently have:

var r="://([^/]+)",l=document.location.href.match(r)[1].split(".");l=l[l.length-2]+"."+l[l.length-1];

This is one of the bloated parts of my script. Can anyone save me a few bytes?

try swapping document.location with top.location

l=(''+top.location).match(/[^/]+$/)[0]

@gwyn
That doesn't execute in firefox, and in IE it only returns the filename

@Virus
Yeah, that does save 5 bytes =)

GwynforWeb

what are you trying to extract from the location string? (it looked the file name to me)

GwynforWeb

would it be 'experts-exchange.com' from say

yes, exactly. i want the "domain name" with any sub domains stripped.
ebay.com for: www.ebay.com, signin.ebay.com, scgi.ebay.com, ebay.com

Etc.

GwynforWeb

in which case it is the above eg

javascript:function x(){alert(l=(''+location.host).match(/[^.]*\.[^.]*$/)[0])}x()

Beautiful Gwyn =) Don't think it can get much smaller than that !

devic

and what's about port? e.g. :8080

Thanks for the points

GwynforWeb

Above submitted from Netscape using

javascript:function x(){document.getElementsByTagName('textarea')[0].value+='Thanks for the points';document.answerQuestionForm.submit()}x()

GwynforWeb

to answer Devic (port number was not in question code)

l=(''+location.hostname).match(/[^.]*\.[^.]*$/)[0]
eg
javascript:function x(){alert(l=(''+location.hostname).match(/[^.]*\.[^.]*$/)[0])}x()

GwynforWeb

this also seems to work with the hostname

l=location.host.match(/[^.]*\.[^.]*$/)[0]

javascript:function x(){alert(l=location.host.match(/[^.]*\.[^.]*$/)[0])}x()
