如何将CKeditor语言设置为插件（jqueryspellchecker）语言？

Question

我有编辑器配置

CKEDITOR.editorConfig = function( config ) {
    config.extraPlugins = 'jqueryspellchecker';
    config.toolbar = 'Basic';     

config.toolbar_Basic =
[
    ['Bold', 'Italic', '-', 'NumberedList','BulletedList','-','Outdent','Indent','-','Blockquote','CreateDiv',
    '-','JustifyLeft','JustifyCenter','JustifyRight','JustifyBlock', '-', 'Link', 'Unlink','-', 'Image','Table','HorizontalRule',
            'Smiley','SpecialChar','PageBreak', 'Styles','Format','Font','FontSize' , 'TextColor',
        'BGColor','jQuerySpellChecker', 'Source']
];

和我的ckeditor都有语言-'lt'，但是我可以从网站上动态更改它。

和plugin.js

CKEDITOR.plugins.add('jqueryspellchecker', {

  config: {
    lang: 'lt',
    parser: 'html',
    webservice: {
      path: '/new/layout/editor/plugins/jqueryspellchecker/webservices/php/SpellChecker.php',
      driver: 'pspell'
    },
    suggestBox: {
      position: 'below',
      appendTo: 'body'
    }
  },

  init: function( editor ) {

    var t = this;
    var pluginName = 'jqueryspellchecker';

    this.config.suggestBox.position = this.positionSuggestBox();

    editor.addCommand(pluginName, {
      canUndo: false,
      readOnly: 1,
      exec: function() {
        t.toggle(editor);
      }
    });

    editor.ui.addButton('jQuerySpellChecker', {
      label: 'SpellCheck',
      icon: 'spellchecker',
      command: pluginName,
      toolbar: 'spellchecker,10'
    });

    editor.on('saveSnapshot', function() {
      t.destroy();
    });
  },

当我在网站上更改编辑器语言时，如何更改plugin.js配置语言？
