JavaScript provides you many methods to retrieve and change the current URL which is displayed in browser's address bar. All these methods uses the Location object, which is a property of the Window object. You can create a new Location object that has the current URL as follows: | |
var currentLocation = window.location; | |
Basic Structure of a URL | |
<protocol>//<hostname>:<port>/<pathname><search><hash> | |
enter image description here | |
Protocol -- Specifies the protocol name be used to access the resource on the Internet. (HTTP (without SSL) or HTTPS (with SSL)) | |
hostname -- Host name specifies the host that owns the resource. For example, www.stackoverflow.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, stackoverflow.com/index.html. | |
query -- 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 | |
