JavaScript Window Location

The window.location object can be used to get the current page address (URL) and to redirect the browser to a new page.

Window Location

The window.location object can be written without the window prefix.

Some examples:

  • window.location.href returns the href (URL) of the current page
  • window.location.hostname returns the domain name of the web host
  • window.location.pathname returns the path and filename of the current page
  • window.location.protocol returns the web protocol used (http: or https:)
  • window.location.assign() loads a new document

Window Location Href

The window.location.href property returns the URL of the current page.

Example

Display the href (URL) of the current page:

document.getElementById("demo").innerHTML =
"Page location is " + window.location.href;

Result is:


Window Location Hostname

The window.location.hostname property returns the name of the internet host (of the current page).

Example

Display the name of the host:

document.getElementById("demo").innerHTML =
"Page hostname is " + window.location.hostname;

Result is:

Window Location Pathname

The window.location.pathname property returns the pathname of the current page.

Example

Display the path name of the current URL:

document.getElementById("demo").innerHTML =
"Page path is " + window.location.pathname;

Result is:

Window Location Protocol

The window.location.protocol property returns the web protocol of the page.

Example

Display the web protocol:

document.getElementById("demo").innerHTML =
"Page protocol is " + window.location.protocol;

Result is:

Window Location Port

The window.location.port property returns the number of the internet host port (of the current page).

Example

Display the name of the host:

document.getElementById("demo").innerHTML =
"Port number is " + window.location.port;

Result is:

Most browsers will not display default port numbers (80 for http and 443 for https)

Window Location Assign

The window.location.assign() method loads a new document.

Example

Load a new document:

<html>
<head>
<script>
function newDoc() {
  window.location.assign("https://www.w3schools.com")
}
</script>
</head>
<body>

<input type="button" value="Load new document" onclick="newDoc()">

</body>
</html>
