JavaScript Window Navigator,

JavaScript Window Navigator,
The window. navigator object contains information about the visitor's browser.

Window Navigator

Window. navigatorObjects can be written without the window prefix.

Instance

<P id = "example"> </p>

<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 !!!

Information from the navigator object is misleading and should not be used to detect the browser version because:

• Navigator data can be changed by browser users
• Some browsers will identify errors on the test site
• The browser cannot report a new OS released later than the browser

Browser Detection

Because navigator can mislead browser detection, object detection can be used to sniff different browsers.

Because different browsers support different objects, you can use objects to detect browsers. For example, because only Opera supports the "window. opera" attribute, you can identify Opera accordingly.

Example: if (window. opera) {... some action ...}
