JavaScript Objects HTML DOM ObjectsJavaScript Window Navigator
The window.navigator object contains information about the visitor's browser.
Window Navigator
The window.navigator object can be written without the window prefix.
Example
<div id="example"></div>
<script>
txt = "<p>Browser CodeName: " + navigator.appCodeName + "</p>";
txt+= "<p>Browser Name: " + navigator.appName + "</p>";
txt+= "<p>Browser Version: " + navigator.appVersion + "</p>";
txt+= "<p>Cookies Enabled: " + navigator.cookieEnabled + "</p>";
txt+= "<p>Platform: " + navigator.platform + "</p>";
txt+= "<p>User-agent header: " + navigator.userAgent + "</p>";
txt+= "<p>User-agent language: " + navigator.systemLanguage + "</p>";
document.getElementById("example").innerHTML=txt;
</script>
<script>
txt = "<p>Browser CodeName: " + navigator.appCodeName + "</p>";
txt+= "<p>Browser Name: " + navigator.appName + "</p>";
txt+= "<p>Browser Version: " + navigator.appVersion + "</p>";
txt+= "<p>Cookies Enabled: " + navigator.cookieEnabled + "</p>";
txt+= "<p>Platform: " + navigator.platform + "</p>";
txt+= "<p>User-agent header: " + navigator.userAgent + "</p>";
txt+= "<p>User-agent language: " + navigator.systemLanguage + "</p>";
document.getElementById("example").innerHTML=txt;
</script>

Warning !!!
The information from the navigator object can often be misleading, and should not be used to detect browser versions because:
- 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
Browser Detection
Since the navigator object can be misleading about browser detection, using object detection can be used to sniff out different browsers.
Since different browsers support different objects, you can use objects to detect browsers. For example, since only Opera supports the property "window.opera", you can use that to identify Opera.
Example: if (window.opera) {...some action...}
