The window.navigator object contains information about the visitor's browser.

Window Navigator

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

Some examples:

• navigator.appName

• navigator.appCodeName

• navigator.platform

Navigator Cookie Enabled

The property cookieEnabled returns true if cookies are enabled, otherwise false:

<p id="demo"></p>

<script>
document.getElementById("demo").innerHTML =
"Cookies Enabled is " + navigator.cookieEnabled;
</script>

The Browser Names

The properties appName and appCodeName return the name of the browser:

<p id="demo"></p>

<script>
document.getElementById("demo").innerHTML =
"Name is " + navigator.appName + ". Code name is " + navigator.appCodeName;
</script>

Did you know?

IE11, Chrome, Firefox, and Safari return appName "Netscape".

Chrome, Firefox, IE, Safari, and Opera all return appCodeName "Mozilla".

The Browser Engine

The property product returns the engine name of the browser:

<p id="demo"></p>

<script>
document.getElementById("demo").innerHTML = navigator.product;
</script>

The Browser Version I

The property appVersion returns version information about the browser:

<p id="demo"></p>

<script>
document.getElementById("demo").innerHTML = navigator.appVersion;
</script>

The Browser Version II

The property userAgent also returns version information about the browser:

<p id="demo"></p>

<script>
document.getElementById("demo").innerHTML = navigator.userAgent;
</script>

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 browser

The Browser Platform

The property platform returns the browser platform (operating system):

<p id="demo"></p>

<script>
document.getElementById("demo").innerHTML = navigator.platform;
</script>
