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

Some examples:

  • 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.
