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。
为方便大家使用,脚本之家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:

FCKEditor SyntaxHighlighter整合实现代码高亮显示

      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:
