描述
the host property specifies a portion of the url. the host property is the concatenation of the hostname and port properties, separated by a colon. when the port property is null, the host property is the same as the hostname property.
you can set the host property at any time, although it is safer to set the href property to change a location. if the host that you specify cannot be found in the current location, you will get an error.
see section 3.1 of rfc 1738 for complete information about the hostname and port.
例子
see the 例子 for the href property.
