SharePoint Multi-languages with JavaScript Code

A my friend asked me how to implement Multi-languages with JavaScript in SharePoint 2010.

With server code, you can use resourced for this.

With JavaScript, you can identify the current language that SharePoint Site is using via _spPageContextInfo object (Ref: http://trungpv.blogspot.com/2011/09/javascript-notes-with-sharepoint.html), it provides the currentLanguage property that allows you know which language is using.

You can define an JavaScript objects like below:

News.DefaultLanguage = 1033;
News.Resources = {};
//English
News.Resources[1033] = {
    Title: "News",
    Function: "Searcj"
};

//Vietnamese
News.Resources[1066] = {
Title: "Tin tức",
Function: "Tìm kiếm"
};

And you can load appropriated resources:

if (News.Resources[_spPageContextInfo.currentLanguage]) {
            res = News.Resources[_spPageContextInfo.currentLanguage];
        } else {
            res = News.Resources[News.DefaultLanguage];
        }
