Definition and Usage
The origin property returns the protocol, hostname and port number of the href attribute value.
The href attribute specifies the destination of a link in an area.
Note: If the port number is not specified in the URL (or if it is the scheme's default port - like 80, or 443), some browsers will not display the port number.
Note: This property is read-only.
