所以就为FCKeditor写了个InsertCode的插件。整个插件的制作过程非常简单：
FCKeditor插件开发请参考FCKeditor官网的文档：

http://docs.fckeditor.net/FCKeditor_2.x/Developers_Guide/Customization/Plug-ins
首先，我们在FCKeditor/editor/plugins目录下新建一个insertcode目录，并在insertcode目录下新建一个fckplugin.js文件。
在新建的fckplugin.js文件中插入下面的代码：
//插入代码
复制代码 代码如下:
FCKCommands.RegisterCommand('InsertCode', new FCKDialogCommand('InsertCode', FCKLang.InsertCode, FCKPlugins.Items['insertcode'].Path + 'insertcode.aspx', 700, 600)) ;
var insertcodeItem = new FCKToolbarButton('InsertCode', FCKLang['InsertCode']) ;
insertcodeItem.IconPath = FCKPlugins.Items['insertcode'].Path + 'images/insertcode.gif';
FCKToolbarItems.RegisterItem('InsertCode', insertcodeItem);



在FCKeditor/editor/plugins/insertcode目录下创建images，lang，languages目录，在lang目录下新建en.js,zh-cn.js。en.js的内容为：
FCKLang.InsertCode = 'Insert Codes' ;
zh-cn.js的内容为：
FCKLang.InsertCode = '插入代码' ;

这次的插件就完工了。这种方法可以说是一劳永逸，以后更换高版本的FCKeditor时，只需要修改fckconfig.js将这个插件加入就可以了
