Browsers


Although most browsers are JavaScript enabled and can understand all JavaScript code, some browsers or the older versions of certain browsers cannot understand JavaScript code and ignore it. This leads to unexpected behavior or undesired results. However, you can handle the situation if you know the browser and the browser version being used by the visitor.

 

Once you know the type and the version of the browser used by the visitors on your website, you can make smart web pages. You can redirect the users to browser specific pages or display them browser specific content. To deal with the problem, JavaScript provides Navigator object that allows you to find out the type of browser its version, and much more. The following properties of the Navigator object allow you to get all the information about the browser:

 

·        appName: This property gives the name of the browser used.

 

·        appVersion: This property gives the version information of the browser used.

 

·        appCodeName: This property gives the code name of the browser used. The code name of both Internet Explorer and Netscape Navigator is “Mozilla”.

 

·        platform: This property gives the information about the platform on which browser is running, such as Windows or Macintosh.

 

·        cookieEnabled: This property gives the information about the cookies. It tells whether the cookies are enabled on the browser or not.

 

·        language: This property gives the language version of the browser. For example ‘en’ would be returned for the English language.

 

·        userAgent: This property gives the information about the appName and appVersion of the browser if the browser does not identify itself with appName and appVersion properties.

 

<html>

<head>

<script type="text/javascript">

document.write("Browser Name: " + navigator.appName);

document.write("<br /><br />");

document.write("Browser Version: " + navigator.appVersion);

document.write("<br /><br />");

document.write("Browser CodeName: " + navigator.appCodeName);

document.write("<br /><br />");

document.write("Cookies Enabled: " + navigator.cookieEnabled);

document.write("<br /><br />");

document.write("Platform: " + navigator.platform);

document.write("<br /><br />");

document.write("User-agent header: " + navigator.userAgent);

</script>

</body>

</html>
