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“editorplugins”,在其中创建“highlighter”文件夹。

第二步:将“dp.SyntaxHighlighterScripts”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——

复制代码 代码如下:

最终目录结构如下:

FCKEditor SyntaxHighlighter整合实现代码高亮显示1

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:
