Change sharepoint server 2010 Display language from Default language to alternate language programmatically

I found a solution on a following issue to change the default language to alternate language programmatically using which the sharepoint designer's actions and conditions language doesn't change below is the javascript code:

_spBodyOnLoadFunctionNames.push('ChangeLanguage');

function ChangeLanguage()

{

//script fetches current display language

var lcid =_spPageContextInfo.currentLanguage;

//1025 language code for arabic

if(lcid.toString()!=1025)

{

var today = new Date();

var oneYear = new Date(today.getTime() + 365 * 24 * 60 * 60 * 1000);

var url = window.location.href;

//script changes current display language to arabic i.e 1025

document.cookie = "lcid=" + 1025 + ";path=/;expires=" + oneYear.toGMTString();

window.location.href = url;

}

}

If any queries do reply.

Regards,
