FCKEditor 添加"插入代码"工具栏按钮

 FCKeditor是一款功能强大的开源在线文本编辑器,刚刚推出的 FCKEditor 2.5 支持IE、Firefox、safari、Oper、Netscape、Camino等等主流浏览器，支持Windows、Mac、Linux平台，支持ASP.Net、ASP、ColdFusion 、PHP 、Java 、 Active-FoxPro、Lasso 、Perl 、Python等语言，生成的代码完全符合XHTML 1.0标准。
其配置方法可参见：http://www.xianfen.net/Article7.aspx
本文讨论 asp.net FCKEditor  中添加"插入代码"工具栏。代码高亮组件用的是免费的 ActiproSoftware.CodeHighlighter ，该组件支持多种语言代码的着色。

(一).添加自定义工具栏


涉及到三组文件：
1.fckeditor\editor\lang下的文件(这是界面多语言支持的文件夹，在此只修改英文和简体中文支持的.js文件)

en.js:

zh-cn.js:

2.fckeditor\editor\js下的文件(这是多浏览器支持的文件夹，FCKEditor 核心代码。为了减少大小，该文件夹的文件已被压缩，未被压缩的文件在"fckeditor\editor\_source"中。
fckeditorcode_gecko.js:提供"类火狐"等浏览器支持。
fckeditorcode_ie.js:提供"类IE"等浏览器支持。
以上文件共要改两处：
(1).在以上文件中查找"default:if (FCKRegexLib"，在default 前插入"case 'InsertCode':B = new FCKDialogCommand('InsertCode' ,FCKLang.InsertCode ,'dialog/InsertCode/InsertCode.aspx',700,600);break"
FCKDialogCommand()方法：
参数1,2:按钮名称，跟前面语言支持文件中定义的对应
参数3:点击该按钮后显示的文件
参数4,5:弹出窗口的宽和高

(2).继续查找"default:alert(FCKLang.UnknownToolbarItem"，在"default"前插入"case 'InsertCode':B = new FCKToolbarButton,'InsertCode', FCKLang.InsertCode,null,null,null,null,69);break;"

最后的参数是工具栏图标的索引(FCKEditor版本不同，索引不同)，图标文件fckeditor\editor\skins\office2003\fck_strip.gif,在图片的最后增加一个16*16的图标。索引计算方法是：该图片高度除16即得到最后一个图标索引号。
3.fckeditor\fckconfig.js


(二).制作InsertCode.aspx 文件(fckeditor\editor\dialog\InsertCode\InsertCode.aspx)

如果其他语言，可参考使用 javascript 代码着色:
