帝国cms编辑器添加一个代码隐藏工具按钮

帝国cms默认的编辑器如何添加一个隐藏代码按钮？比如单击隐藏代码按钮就出现：[ecode]隐藏的内容[/ecode]
这样的代码
思路：参考默认编辑器的插入<br>按钮
1、复制插/e/admin/ecmseditor/infoeditor/plugins/einsertbr后重命名ecode，打开ecode目录下的plugin.js，把所有的einsertcode改成ecode，代码微调了一下。
einsertcode.png 图片修改为ecode.png，图片自己制作。
plugin.js代码：
CKEDITOR.plugins.add('ecode',
{
init: function (editor) {
var pluginName = 'ecode';
editor.addCommand(pluginName, {
exec: function (editor) {
// var b = editor.getSelection(), b = b && b.getRanges()[0];
// a = new CKEDITOR.style({element: "code",});
// c = new CKEDITOR.style({element: "ecode",});
// editor.applyStyle(a);
// editor.applyStyle(c);
//               editor.insertHtml('【ecode】插入内容【/ecode】');
               editor.insertHtml('[ecode]插入内容[/ecode]');
}
}
);

editor.ui.addButton(pluginName,
{
label: 'code标签',
command: pluginName,
icon: this.path + 'images/ecode.png'
});
}
});
2、修改帝国cms编辑器配置文件，路径：/e/admin/ecmseditor/infoeditor/config.js
在文件里面两个地方参考einsertbr添加ecode
config.js代码：

function EcmsEditorDoCKhtml(htmlstr){
   if(htmlstr.indexOf('"')!=-1)
   {
       return '';
   }
   if(htmlstr.indexOf("'")!=-1)
   {
       return '';
   }
   if(htmlstr.indexOf("/")!=-1)
   {
       return '';
   }
   if(htmlstr.indexOf("\\")!=-1)
   {
       return '';
   }
   if(htmlstr.indexOf("[")!=-1)
   {
       return '';
   }
   if(htmlstr.indexOf("]")!=-1)
   {
       return '';
   }
   if(htmlstr.indexOf(":")!=-1)
   {
       return '';
   }
   if(htmlstr.indexOf("%")!=-1)
   {
       return '';
   }
   if(htmlstr.indexOf("<")!=-1)
   {
       return '';
   }
   if(htmlstr.indexOf(">")!=-1)
   {
       return '';
   }
   return htmlstr;
}

function EcmsEditorGetCs(){
   var js=document.getElementsByTagName("script");
   for(var i=0;i<js.length;i++)
   {
       if(js[i].src.indexOf("ckeditor.js")>=0)
       {
           var arraytemp=new Array();
           arraytemp=js[i].src.split('?');
           return arraytemp;
       }
   }
}

var arraycs=new Array();
arraycs=EcmsEditorGetCs();

arraycs[0]=arraycs[0].replace('infoeditor/ckeditor.js','');

arraycs[1]=document.getElementById('doecmseditor_eaddcs').value;
arraycs[1]=EcmsEditorDoCKhtml(arraycs[1]);

CKEDITOR.editorConfig = function( config ) {
   // Define changes to default configuration here. For example:
   // config.language = 'fr';
   // config.uiColor = '#AADC6E';

   config.filebrowserImageUploadUrl = '';
   config.filebrowserFlashUploadUrl = arraycs[0];
   config.filebrowserImageBrowseUrl = arraycs[1];
   config.filebrowserFlashBrowseUrl = arraycs[1];

   config.enterMode = CKEDITOR.ENTER_BR;
   config.shiftEnterMode = CKEDITOR.ENTER_P;

   config.allowedContent= true;

   config.font_names='宋体/宋体;黑体/黑体;仿宋/仿宋_GB2312;楷体/楷体_GB2312;隶书/隶书;幼圆/幼圆;微软雅黑/微软雅黑;'+ config.font_names;

   // Toolbar
   config.toolbar_full = [
   { name: 'document', groups: [ 'mode', 'document', 'doctools' ], items: [ 'Source', '-', 'Preview', 'Print' ] },
   { name: 'clipboard', groups: [ 'clipboard', 'undo' ], items: [ 'Cut', 'Copy', 'Paste', 'PasteText', 'PasteFromWord', '-', 'Undo', 'Redo' ] },

   '/',
   { name: 'basicstyles', groups: [ 'basicstyles', 'cleanup' ], items: [ 'Bold', 'Italic', 'Underline', 'Strike', 'Subscript', 'Superscript', '-', 'RemoveFormat', 'ecleanalltext', 'autoformat' ] },

   { name: 'links', items: [ 'Link', 'Unlink', 'Anchor' ] },

   { name: 'colors', items: [ 'TextColor', 'BGColor' ] },
   { name: 'tools', items: [ 'ShowBlocks', 'NewPage', 'Templates' ] },
   { name: 'others', items: [ '-' ] },
   { name: 'editing', groups: [ 'find', 'selection', 'spellchecker' ], items: [ 'Find', 'Replace', '-', 'SelectAll', 'Maximize' ] }
];

   // Toolbar
   config.toolbar_basic = [
   { name: 'document', groups: [ 'mode', 'document', 'doctools' ], items: [ 'Source' ] },
   { name: 'clipboard', groups: [ 'clipboard', 'undo' ], items: [ 'Cut', 'Copy', 'Paste', 'PasteText', 'PasteFromWord', '-', 'Undo', 'Redo' ] },
   { name: 'links', items: [ 'Link', 'Unlink', 'Anchor' ] },
   { name: 'insert', items: [ 'Image', 'Table', 'HorizontalRule', 'SpecialChar' ] },
   { name: 'tools', items: [ 'Maximize' ] },
   { name: 'others', items: [ '-' ] },
   '/',

   { name: 'paragraph', groups: [ 'list', 'indent', 'blocks', 'align', 'bidi' ], items: [ 'NumberedList', 'BulletedList', '-', 'Outdent', 'Indent', '-', 'Blockquote' ] },
   { name: 'styles', items: [ 'Styles', 'Format' ] }
];

   config.extraPlugins = 'etranfile,etranmedia,etranmore,autoformat,ecleanalltext,einsertbr,ecode,einsertpage,einserttime,equotetext';


   config.toolbar = 'full';



};

ps：这是必须要做的，要不然可能看不到效果。
