I have couple labels and tabs in my site and I need to make possible to user to change language of that l开发者_JS百科abels and tabs. How to achieve this ? Is there something already done in Dojo or plain Javascript for this ?

There is mechanism of internalization and localization in Dojo. You can read documentation about dojo.i18n

you can use css classes to specify what multi language content an element must support see http://jsfiddle.net/AJKTx/
