  // Load the Google Transliteration API
  google.load("elements", "1", {
        packages: "transliteration"
      });

  var transliterationControl;
  function onLoad() {
    var options = {
        sourceLanguage: 'en',
        destinationLanguage: ['ar','hi','kn','ml','ta','te'],
        transliterationEnabled: true,
        shortcutKey: 'ctrl+g'
    };
    // Create an instance on TransliterationControl with the required
    // options.
    transliterationControl =
      new google.elements.transliteration.TransliterationControl(options);

    // Enable transliteration in the textfields with the given ids.
    var ids = [ "transl1", "transl2" ];
    transliterationControl.makeTransliteratable(ids);

    // Add the STATE_CHANGED event handler to correcly maintain the state
    // of the checkbox.
    transliterationControl.addEventListener(
        google.elements.transliteration.TransliterationControl.EventType.STATE_CHANGED,
        transliterateStateChangeHandler);

    // Add the SERVER_UNREACHABLE event handler to display an error message
    // if unable to reach the server.
    transliterationControl.addEventListener(
        google.elements.transliteration.TransliterationControl.EventType.SERVER_UNREACHABLE,
        serverUnreachableHandler);

    // Add the SERVER_REACHABLE event handler to remove the error message
    // once the server becomes reachable.
    transliterationControl.addEventListener(
        google.elements.transliteration.TransliterationControl.EventType.SERVER_REACHABLE,
        serverReachableHandler);

    // Set the checkbox to the correct state.
    document.getElementById('checkboxId').checked =
      transliterationControl.isTransliterationEnabled();

    // Populate the language dropdown
    var destinationLanguage =
      transliterationControl.getLanguagePair().destinationLanguage;
    var languageSelect = document.getElementById('languageDropDown');
    var supportedDestinationLanguages =
      google.elements.transliteration.getDestinationLanguages(

      }
      try {
        languageSelect.add(opt, null);
      } catch (ex) {
        languageSelect.add(opt);
      }
    }
  }

  // Handler for STATE_CHANGED event which makes sure checkbox status
  // reflects the transliteration enabled or disabled status.
  function transliterateStateChangeHandler(e) {
    document.getElementById('checkboxId').checked = e.transliterationEnabled;
  }

  // Handler for checkbox's click event.  Calls toggleTransliteration to toggle
  // the transliteration state.
  function checkboxClickHandler() {
    transliterationControl.toggleTransliteration();
  }

  // Handler for dropdown option change event.  Calls setLanguagePair to
  // set the new language.
  function languageChangeHandler() {
    var dropdown = document.getElementById('languageDropDown');
    transliterationControl.setLanguagePair(
        google.elements.transliteration.LanguageCode.ENGLISH,
        dropdown.options[dropdown.selectedIndex].value);
