How to use i18n with out creating new page for each language type

[shridhar_sahu]

Hello Sir,

I have a Index page Which shows following options for language.

How do i change language for that index page without redirecting to index/hi or index/en or index/fr language specific page.

Also is there any way to change  jcr:language of a CurrentPage using sightly and jquery??

My ultimate Goal is to translate the content in Hindi when a user click on Hindi[Note: This should happen without redirecting to any other url(index/hi)]
