JavaScript provides you with many methods to retrieve and change the current URL, which is displayed in the browser’s address bar. All these methods use the Location
object, which is a property of the Window object. You can create a new Location an object that has the current URL as follows:
var currentLocation = window.location;
Basic URL Structure
<protocol>//<hostname>:<port>/<pathname><search><hash>
- protocol: Specifies the protocol name be used to access the resource on the Internet. (HTTP (without SSL) or HTTPS (with SSL))
- hostname: Hostname specifies the host that owns the resource. For example,
www.eyehunts.com
. A server provides services using the name of the host. - port: A port number used to recognize a specific process to which an Internet or other network message is to be forwarded when it arrives at a server.
- pathname: The path gives info about the specific resource within the host that the Web client wants to access. For example,
/index.html
. - search: A query string follows the path component, and provides a string of information that the resource can utilize for some purpose (for example, as parameters for a search or as data to be processed).
- hash: The anchor portion of a URL, includes the hash sign (#).
With these Location
object properties you can access all of these URL components and what they can set or return:
- href – the entire URL
- protocol – the protocol of the URL
- host – the hostname and port of the URL
- hostname – the hostname of the URL
- port – the port number the server uses for the URL
- pathname – the pathname of the URL
- search – the query portion of the URL
- hash – the anchor portion of the URL
