Location Object

The Location object represents the URL of the object it is linked to, and any modifications made are reflected in the associated object. Both the Document and Window objects have a link to Location, which can be accessed through document.location and window.location, respectively.

Properties

  • location.href: Contains a DOMString of the entire URL, where DOMString is a UTF-16 string that directly maps to a String in JavaScript.
  • location.protocol: Contains the protocol of the URL as a DOMString, followed by a :.
  • location.host: Contains the domain name as a DOMString, possibly followed by a : and the URL's port number.
  • location.hostname: Contains the domain name of the URL as a DOMString.
  • location.port: Contains the port number as a DOMString.
  • location.pathname: Contains the path component of the URL as a DOMString, starting with a /.
  • location.search: Contains the URL parameters as a DOMString, starting with a ?.
  • location.hash: Contains the fragment identifier as a DOMString, starting with a #.
  • location.origin: Read-only, contains the standard form DOMString of the page's domain of origin.
  • location.ancestorOrigins: Read-only, returns a static DOMStringList that includes in reverse order the origins of all ancestor browsing contexts associated with the given Location object. This can be used to determine if a site has framed an iframe document. This property is currently still in the proposal stage.

Methods

  • location.assign(): Loads the content resource of the given URL to the object associated with this Location object, effectively loading a new document.
  • location.reload(): Reloads the resource from the current URL, with a special optional parameter of type Boolean. When this parameter is true, the method will always force the refresh to load data from the server. If the parameter is false or not specified, the browser may load the page from cache.
  • location.replace(): Replaces the current resource with the given URL. Unlike the assign() method, the new page replaced by replace() will not be stored in the session history, meaning the user cannot return to the page using the back button.
  • location.toString(): Returns a DOMString containing the entire URL, equivalent to reading location.href, but using it will not modify the value of location.
