asp.net 为FCKeditor开发代码高亮插件实现代码

所以就为FCKeditor写了个InsertCode的插件。整个插件的制作过程非常简单：
FCKeditor插件开发请参考FCKeditor官网的文档：

http://docs.fckeditor.net/FCKeditor_2.x/Developers_Guide/Customization/Plug-ins
首先，我们在FCKeditor/editor/plugins目录下新建一个insertcode目录，并在insertcode目录下新建一个fckplugin.js文件。
在新建的fckplugin.js文件中插入下面的代码：
//插入代码

复制代码代码如下:

FCKCommands.RegisterCommand('InsertCode', new FCKDialogCommand('InsertCode', FCKLang.InsertCode, FCKPlugins.Items['insertcode'].Path + 'insertcode.aspx', 700, 600)) ; 
var insertcodeItem = new FCKToolbarButton('InsertCode', FCKLang['InsertCode']) ; 
insertcodeItem.IconPath = FCKPlugins.Items['insertcode'].Path + 'images/insertcode.gif'; 
FCKToolbarItems.RegisterItem('InsertCode', insertcodeItem); 

在FCKeditor/editor/plugins/insertcode目录下创建images，lang，languages目录，在lang目录下新建en.js,zh-cn.js。en.js的内容为：
FCKLang.InsertCode = 'Insert Codes' ;
zh-cn.js的内容为：
FCKLang.InsertCode = '插入代码' ;
下载CodeHighlighter https://www.jb51.net/codes/94.html
控件并解压，把CodeHighlighter/bin目录下的ActiproSoftware.CodeHighlighter.Net20.dll,ActiproSoftware.Shared.Net20.dll,CodeHighlighterTest.dll三个DLL复制到BlogEngine.Web/bin目录，
将CodeHighlighter/Languages里的Lexers整个目录复制到FCKeditor/editor/plugins/insertcode/languages目录，
将CodeHighlighter/Images/OutliningIndicators/目录下的所有图片复制到FCKeditor/editor/plugins/insertcode/images目录，并将这个图片下载保存到FCKeditor/editor/plugins/insertcode/images/insertcode.gif。

在FCKeditor/editor/plugins/insertcode/目录下新建insertcode.aspx，注意，如果是用Visual Studio新建的话

insertcode.aspx内容如下：

复制代码代码如下:

%@ Page Language="C#" ValidateRequest="false" %> 

%@ Register TagPrefix="CH" Namespace="ActiproSoftware.CodeHighlighter" Assembly="ActiproSoftware.CodeHighlighter.Net20" %>

static string code = string.Empty; 

protected void btnSubmit_Click(object sender, EventArgs e) 
...{ 
code = txtCode.Text; 
Highlighter.LanguageKey = ddlLangType.SelectedItem.Text; 
Highlighter.OutliningEnabled = chkOutLining.Checked; 
Highlighter.LineNumberMarginVisible = chkLineNum.Checked; 
Highlighter.Text = code; 
} 
protected void Page_Load(object sender, EventArgs e) 
...{ 
if (!Page.IsPostBack) 
...{ 
CodeHighlighterConfiguration config = (CodeHighlighterConfiguration)ConfigurationManager.GetSection("codeHighlighter"); 
string[] keys = new string[config.LanguageConfigs.Keys.Count]; 
config.LanguageConfigs.Keys.CopyTo(keys, 0); 
Array.Sort(keys); 
foreach (string key in keys) 
...{ 
ddlLangType.Items.Add(key); 
} 
ddlLangType.SelectedIndex = ddlLangType.Items.IndexOf(ddlLangType.Items.FindByText("C#")); 
} 
} 

protected void CodeHighlighter_PostRender(object sender, EventArgs e) 
...{ 
if (!string.IsNullOrEmpty(Highlighter.Output)) 
...{ 
lblCode.Text = Highlighter.Output.Replace(" ", "nbsp;nbsp;").Replace("\n", "br />"); 
Response.Write("scr" + "ipt>window.parent.SetOkButton( true );/scr" + "ipt>"); 
} 
} 
/script>

var oEditor = window.parent.InnerDialogLoaded() ;

var oDOM = oEditor.FCK.EditorDocument ; 

var oActiveEl = oEditor.FCKSelection.GetSelectedElement() ; 

window.onload = function()

function Ok()

/div> 
/form> 
/body>

接下来修改FCKeditor/fckconfig.js，在原文件中我们能找到// FCKConfig.Plugins.Add( 'autogrow' ) ;这段代码，在这段代码下一行插入：FCKConfig.Plugins.Add( 'insertcode' , 'zh-cn,en' ) ;

最后修改Web.config文件：（请参考CodeHighlighter/Web.config）
在configuration>里插入：
configSections>
section name="codeHighlighter" requirePermission="false" type="ActiproSoftware.CodeHighlighter.CodeHighlighterConfigurationSectionHandler, ActiproSoftware.CodeHighlighter.Net20" />
/configSections>

在system.web>/system.web>后插入：
codeHighlighter>
cache languageTimeout="3" />
keywordLinking enabled="true" target="_blank" defaultKeywordCollectionKey="ActiproKeywords">
keywordCollection key="ActiproKeywords">
explicitKeyword tokenKey="IdentifierToken" patternValue="Actipro" url="http://www.actiprosoftware.com" caseSensitive="false" />
explicitKeyword tokenKey="IdentifierToken" patternValue="CodeHighlighter" url="http://www.codehighlighter.com" caseSensitive="false" />

这次的插件就完工了。这种方法可以说是一劳永逸，以后更换高版本的FCKeditor时，只需要修改fckconfig.js将这个插件加入就可以了
