FCKEditor SyntaxHighlighter整合实现代码高亮显示
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。
为方便大家使用，特提供两个已经做成插件的版本。下载地址
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——
复制代码 代码如下:
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。
复制代码 代码如下:
// 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" 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——

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：
复制代码 代码如下:
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：
复制代码 代码如下:
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：
