Hi I want to detect a language and display it which language it belongs to ,
Is there any way.

Google code playground: http://code.google.com/apis/ajax/playground/
However, if you want to check the language of a whole page - search for the html/meta details, e.g.
<html xmlns="http://www.w3.org/1999/xhtml" lang="cy_GB" xml:lang="cy_GB">
