Location

The Location interface represents the location (URL) of the object it is linked to. Changes done on it are reflected on the object it relates to. Both the Document and Window interface have such a linked Location, accessible via Document.location and Window.location respectively.

Properties

Location.href

Is a stringifier that returns a USVString containing the entire URL. If changed, the associated document navigates to the new page. It can be set from a different origin than the associated document.

Location.protocol

Is a USVString containing the protocol scheme of the URL, including the final ':'.

Location.host

Is a USVString containing the host, that is the hostname, a ':', and the port of the URL.

Location.hostname

Is a USVString containing the domain of the URL.

Location.port

Is a USVString containing the port number of the URL.

Location.pathname

Is a USVString containing an initial '/' followed by the path of the URL.

Location.search

Is a USVString containing a '?' followed by the parameters or "querystring" of the URL. Modern browsers provide URLSearchParams and URL.searchParams to make it easy to parse out the parameters from the querystring.

Location.hash

Is a USVString containing a '#' followed by the fragment identifier of the URL.

Location.username

Is a USVString containing the username specified before the domain name.

Location.password

Is a USVString containing the password specified before the domain name.

Location.origin Read only

Returns a USVString containing the canonical form of the origin of the specific location.

Methods

Location.assign()

Loads the resource at the URL provided in parameter.

Location.reload()

Reloads the resource from the current URL. Its optional unique parameter is a Boolean, which, when it is true, causes the page to always be reloaded from the server. If it is false or not specified, the browser may reload the page from its cache.

Location.replace()

Replaces the current resource with the one at the provided URL. The difference from the assign() method is that after using replace() the current page will not be saved in session History, meaning the user won't be able to use the back button to navigate to it.

Location.toString()

Returns a USVString containing the whole URL. It is a synonym for HTMLHyperlinkElementUtils.href, though it can't be used to modify the value.

Examples

// Create anchor element and use href property for the purpose of this example
// A more correct alternative is to browse to the URL and use document.location or window.location
var url = document.createElement('a');
url.href = 'https://developer.mozilla.org:8080/en-US/search?q=URL#search-results-close-container';
console.log(url.href);      // https://developer.mozilla.org:8080/en-US/search?q=URL#search-results-close-container
console.log(url.protocol);  // https:
console.log(url.host);      // developer.mozilla.org:8080
console.log(url.hostname);  // developer.mozilla.org
console.log(url.port);      // 8080
console.log(url.pathname);  // /en-US/search
console.log(url.search);    // ?q=URL
console.log(url.hash);      // #search-results-close-container
console.log(url.origin);    // https://developer.mozilla.org:8080
