JavaScript - Location Object

Window Location Object

The location object in JavaScript provides information about the browser's location, i.e., URLs. It is a built-in property of both the window and document objects. We can access it using either window.location or document.location.

The 'location' object contains various properties and methods to get and manipulate the information of the browser's location (URL).

JavaScript Location Object Properties

We can use the properties of the location object to get information of URL:

hash − This property is used to set or get the anchor part of the URL.
host − This property is used to set or get the hostname or port number of the URL.
hostname − This property is used to set the hostname.
href − This property is used to set or get the URL of the current window.
origin − This property returns the protocol, domain, and port of the URL.
pathname − This property updates or gets the path name.
port − This property updates or gets the port of the URL.
protocol − This property updates or gets the protocol.
search − This property is used to set or get the query string of the URL.

Syntax

Follow the syntax below to access the location object's properties and methods −

window.location.property;

location.property;

You may use the 'window' object to access the 'location' object.

Here, we have demonstrated the use of some properties of the location object with examples.

Example: Accessing location host property

The location.host property returns the host from the current URL. However, you can also change the host using it.

In the below code, we extract the host from the URL. You can see that it returns 'www.tutorialspoint.com'.

<html>
<body>
   <div id="output"></div>
   <script>
      const host = location.host;
      document.getElementById("output").innerHTML =
	  "The host of the current location is: " + host;
   </script>
</body>
</html>

Output

The host of the current location is: www.tutorialspoint.com

Example: Accessing location protocol property

The location.protocol propery is used to get used in the current URL. You can also use it to update the protocol.

Try the following example to use the location.protocol property -

<html>
<body>
   <div id = "output"> </div>
   <script>
      document.getElementById("output").innerHTML = 
      "The protocol of the current location is: " + location.protocol;    
   </script>
</body>
</html>

Output

The protocol of the current location is: https:

Example: Accessing location hostname property

The location.hostname property returns the host name of the current URL. You can use it to the hostname as well.

Try the following example to use location.hostname property –

<html>
<body>
   <div id = "output"> </div>
   <script>
      document.getElementById("output").innerHTML = 
      "The host name of the current location is: " + location.hostname;    
   </script>
</body>
</html>

Output

The host name of the current location is: www.tutorialspoint.com

Example: Accessing location pathname property

The location.pathname property returns the path name of the current location. You can set the path name using it.

<html>
<body>
   <div id = "output"> </div>
   <script>
      document.getElementById("output").innerHTML = 
      "The protocol of the current location is: " + location.pathname;    
   </script>
</body>
</html>

Output

The protocol of the current location is: /javascript/javascript_location_object.htm

JavaScript Location Object Methods

We can also use the methods of the location object to navigation to new URLs −

assign(url) − This method loads a new document at the specified URL.
replace(url) − This method replaces the current document with a new document at the specified URL.
reload() − This method reloads the current document.

JavaScript location assign() method

The location.assign() method takes the URL and changes the URL in the current window. In short, it opens a new web page.

Syntax

Follow the syntax below to use the location.assign() method in JavaScript −

location.assign();

Example

In the below code, when you click the 'Go to home page' button, it will redirect you to the home page of the tutorialpoint website.

<html>
<body>
   <div id="output"></div>
   <button onclick="changePage()">Go to Home Page</button>
   <script>
      let output = document.getElementById("output");
      function changePage() {
	     window.location.assign("https://www.tutorialspoint.com/");
      }
   </script>
</body>
</html>
