// Load the Google Transliterate API

google.load("elements", "1", {

packages: "transliteration"

});

var options = {

sourceLanguage:

google.elements.transliteration.LanguageCode.ENGLISH,

destinationLanguage:

[google.elements.transliteration.LanguageCode.MARATHI],

shortcourtkey: 'ctrl+e',

transliterationEnabled: true

};

// Create an instance on TransliterationControl with the required

// options.

var control = new google.elements.transliteration.TransliterationControl(options);

// Enable transliteration in the textbox with id

// 'transliterateTextarea'.

control.makeTransliteratable(['FirstName']);
