Is there a really easy way to start from a full URL:
document.location.href = "http://aaa.bbb.ccc.com/asdf/asdf/sadf.aspx?blah" And extract just the host part:
aaa.bbb.ccc.com There's gotta be a JavaScript function that does this reliably, but I can't find it.

The getHost() method of URL class returns the hostname of the URL. This method will return the IPv6 address enclosed in square brackets ('['and']').
If you only want to return the hostname value (excluding the port number), use the window. location. hostname method instead. This will return a string value containing the hostname and, if the port value is non-empty, a : symbol along with the port number of the URL.
hostname property returns the host (IP adress or domain) of a URL. The location. hostname property can also be set, to navigate to the same URL with a new hostname.
The Location Host property in HTML is used to sets or returns the hostname and port of a URL. The Location Hash property doesn't return the port number if it is not specified in the URL. Syntax: It returns the host property.
suppose that you have a page with this address: http://sub.domain.com/virtualPath/page.htm. use the following in page code to achive those results:
window.location.host : you'll get sub.domain.com:8080 or sub.domain.com:80 window.location.hostname : you'll get sub.domain.com window.location.protocol : you'll get http: window.location.port : you'll get 8080 or 80 window.location.pathname : you'll get /virtualPath window.location.origin : you'll get http://sub.domain.com *****Update: about the .origin
***** As the ref states, browser compatibility for window.location.origin is not clear. I've checked it in chrome and it returned http://sub.domain.com:port if the port is anything but 80, and http://sub.domain.com if the port is 80.
Special thanks to @torazaburo for mentioning that to me.
