I have used the excellent gskinner.com/RegExr/ tool to test my string matching regex but I cannot figure out how to implement this into my JavaScript file to return true or false.
The code I have is as follows:
^(http:)\/\/(.+\.)?(stackoverflow)\.
on a url such as http://stackoverflow.com/questions/ask
this would match (according to RegExr) http://stackoverflow.
So this is great because I want to try matching the current window.location
to that string, but the issue I am having is that this JavaScript script does not work:
var url = window.location;
if ( url.match( /^(http:)\/\/(.+\.)?(stackoverflow)\./ ) )
{
alert('this works');
};
Any ideas on what I am doing wrong here?
Thanks for reading.

If you want to test domain name (host) window.location.host
gives you what you need (with subdomain)
if( /^(.*\.)?stackoverflow\./.test(window.location.host) ){
alert('this works');
}
window.location
is not a string; it's an object. Use window.location.href
