近日做个小网站，用到了代码高亮嵌入显示功能，想将FCKeditor和dp.SyntaxHighlighter结合使用。因此上网查了许多资料，没有说怎么做的，都是自己改好一个包上传。我研究了一个这些整合好的例子，粗略说一说，对以后开发其它FCKeditor插件也有好处。

第一步：在FCKeditor的路径中找到“editor/plugins/”，在其中创建“highlighter”文件夹。

第二步：将“dp.SyntaxHighlighter/Scripts”文件夹复制到此文件夹中，所有的js文件和一个flash文件也要一通复制过来。

第三步：在“highlighter/”创建“lang”文件夹，在其中新建“zh-cn.js”文件，内容如下——

FCKLang.CodeBtn = '插入高亮代码' ;FCKLang.CodeArea = '代码';FCKLang.CodeDlgTitle = '插入高亮代码' ;FCKLang.CodeDlgName = '语言' ;FCKLang.CodeErrNoName = '请输入代码' ;

第四步：在“highlighter/”创建“fckplugin.js”，内容如下——此文件内容也可以参考其他plugins目录下的同名文件。

// Register the related commands.//FCKCommands.RegisterCommand( 'HighLighter', new FCKDialogCommand("HighLighter",FCKLang.DlgHighLighterTitle,FCKConfig.Plugins.Items['highlighter'].Path + 'highlighter.html', 540, 540 ) ) ;FCKCommands.RegisterCommand( 'HighLighter', new FCKDialogCommand("HighLighter",FCKLang['CodeDlgTitle'],FCKConfig.PluginsPath + 'highlighter/highlighter.html', 540, 500 ) ) ;// Create the "highlighter" toolbar button.var oHighLighterItem= new FCKToolbarButton( 'HighLighter', FCKLang['CodeBtn'] ) ;oHighLighterItem.IconPath= FCKConfig.PluginsPath + 'highlighter/highlighter.gif' ;FCKToolbarItems.RegisterItem( 'HighLighter', oHighLighterItem );// 'HighLighter' is the name used in the Toolbar config.var FCKHighLighter = new Object();var CSS_PATH = FCKConfig.PluginsPath + "highlighter/dp.SyntaxHighlighter/Styles/";var pool = {"firstCss" : true };FCKHighLighter.Add = function( value ){var oDiv = FCK.CreateElement("div"); oDiv._FCKhighLighter = "hlDiv" + Math.random() ; oDiv.className="dp-highlighter";oDiv.innerHTML = value;if(pool.firstCss) {pool.firstCss = false;//oDiv.innerHTML += "<link href="" + CSS_PATH + "SyntaxHighlighter.css" mce_href="" + CSS_PATH + "SyntaxHighlighter.css"" + "type='text/css' rel='stylesheet'></link>";}// alert(oDiv.innerHTML);}FCKHighLighter.OnDoubleClick = function( div ){//if(div._FCKhighLighter = "hlDiv") FCKCommands.GetCommand( 'HighLighter' ).Execute() ;if(div.className == "dp-highlighter" && div.tagName=="DIV") FCKCommands.GetCommand( 'HighLighter' ).Execute() ;}FCK.RegisterDoubleClickHandler( FCKHighLighter.OnDoubleClick, 'DIV' ) ;

第五步：找一个21×21px的gif图片作为按钮，取名为“highlighter.gif”。

第六步：关键步骤，创建插入代码对话框，取名为“highlighter.html”。内容如下——

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"><html xmlns="http://www.w3.org/1999/xhtml"><head><meta http-equiv="pragma" content="no-cache" /><meta http-equiv="Cache-Control" content="no-cache, must-revalidate" /><meta http-equiv="expires" content="Wed, 26 Feb 1997 08:21:57 GMT" /><meta http-equiv="expires" content="0" /><mce:script type="text/javascript" src="dp.SyntaxHighlighter/Scripts/shCore.js" mce_src="dp.SyntaxHighlighter/Scripts/shCore.js" ></mce:script><mce:script type="text/javascript" src="dp.SyntaxHighlighter/Scripts/shBrushCSharp.js" mce_src="dp.SyntaxHighlighter/Scripts/shBrushCSharp.js"></mce:script><mce:script type="text/javascript" src="dp.SyntaxHighlighter/Scripts/shBrushPhp.js" mce_src="dp.SyntaxHighlighter/Scripts/shBrushPhp.js"></mce:script><mce:script type="text/javascript" src="dp.SyntaxHighlighter/Scripts/shBrushJScript.js" mce_src="dp.SyntaxHighlighter/Scripts/shBrushJScript.js"></mce:script><mce:script type="text/javascript" src="dp.SyntaxHighlighter/Scripts/shBrushJava.js" mce_src="dp.SyntaxHighlighter/Scripts/shBrushJava.js"></mce:script><mce:script type="text/javascript" src="dp.SyntaxHighlighter/Scripts/shBrushVb.js" mce_src="dp.SyntaxHighlighter/Scripts/shBrushVb.js"></mce:script><mce:script type="text/javascript" src="dp.SyntaxHighlighter/Scripts/shBrushSql.js" mce_src="dp.SyntaxHighlighter/Scripts/shBrushSql.js"></mce:script><mce:script type="text/javascript" src="dp.SyntaxHighlighter/Scripts/shBrushXml.js" mce_src="dp.SyntaxHighlighter/Scripts/shBrushXml.js"></mce:script><mce:script type="text/javascript" src="dp.SyntaxHighlighter/Scripts/shBrushDelphi.js" mce_src="dp.SyntaxHighlighter/Scripts/shBrushDelphi.js"></mce:script><mce:script type="text/javascript" src="dp.SyntaxHighlighter/Scripts/shBrushPython.js" mce_src="dp.SyntaxHighlighter/Scripts/shBrushPython.js"></mce:script><mce:script type="text/javascript" src="dp.SyntaxHighlighter/Scripts/shBrushRuby.js" mce_src="dp.SyntaxHighlighter/Scripts/shBrushRuby.js"></mce:script><mce:script type="text/javascript" src="dp.SyntaxHighlighter/Scripts/shBrushCss.js" mce_src="dp.SyntaxHighlighter/Scripts/shBrushCss.js"></mce:script><mce:script type="text/javascript" src="dp.SyntaxHighlighter/Scripts/shBrushCpp.js" mce_src="dp.SyntaxHighlighter/Scripts/shBrushCpp.js"></mce:script><title>插入代码</title><mce:script language="javascript" type="text/javascript"></mce:script></head><body> <table style="width:100%;"> <tr> <td style="width:10%; line-height:25px;"><span fckLang="CodeDlgName"></span></td> <td> <select id="codeType" style="width:250px;" onchange="document.getElementById('code').className =this.value;"> <option value="csharp">C#</option> <option value="php">PHP</option> <option value="javascript">Javascript</option> <option value="xml">Xml</option> <option value="xml">Html</option> <option value="css">Css</option> <option value="cpp">C/C++</option> <option value="delphi">Delphi</option> <option value="java">Java</option> <option value="python">Python</option> <option value="ruby">Ruby</option> <option value="sql">Sql</option> <option value="vb">VB</option> </select> </td> </tr> <tr> <td><span fckLang="CodeArea"></span></td> <td> <textarea rows="25" cols="80" class="csharp" name="code" id="code">

最终目录结构如下：

第七步：找到“fckconfig.js”文件。（这是fckeditor的核心配置文件，应该能找到的吧……）找“FCKConfig.ToolbarSets”这个key，然后在里面加入“'HighLighter'”。例如：

FCKConfig.ToolbarSets["Basic"] = [['Style','FontFormat','FontName','FontSize','-','Bold','Italic','-','TextColor','BGColor','-','HighLighter']

第八步：还是在“fckconfig.js”中，找到“FCKConfig.Plugins”这个key，添加如下代码：

FCKConfig.Plugins.Add( 'highlighter','zh-cn') ;

好了，以FCKEditor插件形式出现的SyntaxHighlighter代码高亮显示就完成了。

最终效果如图：
