get domain name from url

[sreemathy2000]

i need to get the domain name from the url in javascript.

for eg if the url is "http://bytes.com/forum/newthread.php", i need to get bytes.com alone.

any quick help will be appreciated.

you may use:

[CODE=javascript]var hn = window.location .hostname;[/CODE]

Thanks for the quick reply....this returns the domain name of the current url...
i need this to be a utility function where i can pass a url and get the domain name.

hmmm ... that's another question ... try a regExp like the following:

[CODE=javascript]var url = 'http://bytes.com/forum/newthread.php';

function get_hostname_fr om_url(url) {
return url.match(/:\/\/(.[^/]+)/)[1];
}

alert(get_hostn ame_from_url(ur l));[/CODE]
kind regards

looks a little fragile.

try url.split(/\/+/g)[1];
