Discussion on: Need help cleaning up this code, which modifies the subdomain.

[Kasey Speakman]

var subdomainMatch = /^[^.]+\./;
var admin = window.location.host.replace(subdomainMatch, "admin.");

This is using a regex, but at least it is a small one.

op	meaning
^	line starts with
[^	any character except the following
.	the character .
]	end of character list
+	match one or more of the preceding (any character except .)
\.	match the character .

gorgeous! I love me some regex. I was trying to do this yesterday but going about it all wrong. I was trying to abstract out the last part of the domain. Should have made it easy on myself and just find/replace the subdomain! Thank you!
