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:

var hn = window.location.hostname;

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:

var url = 'http://bytes.com/forum/newthread.php';
 
function get_hostname_from_url(url) {
    return url.match(/:\/\/(.[^/]+)/)[1];
}
 
alert(get_hostname_from_url(url));

kind regards

looks a little fragile.

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