Definition and Usage Window Navigator..
The window.navigator object contains information about the visitor's browser.
The window.navigator object can be written without the window prefix.

  • navigator.platform
  • Browser Cookies
The cookieEnabled property returns true if cookies are enabled, otherwise false:

Warning !!!
  • The information from the navigator object can often be misleading, and should not be used to detect browser versions because:
  • Different browsers can use the same name
  • The navigator data can be changed by the browser owner
  • Some browsers misidentify themselves to bypass site tests
  • Browsers cannot report new operating systems, released later than the browse
The Browser Platform
The platform property returns the browser platform (operating system):
The Browser Language
The language property returns the browser's language:
Is The Browser Online?
The onLine property returns true if the browser is online:

<p>Strange enough, "Netscape" is the application name for both IE11, Chrome, Firefox, and Safari.</p>
<p>Do not rely on it! Most browsers returns "Gecko" as product name!</p>
