为FCKeditor开发代码高亮插件

        昨天已经将BlogEngine的可视化编辑器换成了FCKeditor，作为一个程序员，在博客中插入代码是很重要的一块。网上现有的都是修改FCKeditor的fckeditorcode_gecko.js和fckeditorcode_ie.js以达到InsertCode的目的。这个方法非常麻烦，当要使用FCKeditor新版本时都要重新修改这两个文件，非常影响我们的效率。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
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（http://www.actiprosoftware.com/Download/Freeware.aspx?ProductGroupKey=CH）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：

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

<%@ Register TagPrefix="CH" Namespace="ActiproSoftware.CodeHighlighter" Assembly="ActiproSoftware.CodeHighlighter.Net20" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<script runat="server">
    static string code = string.Empty;

    protected void btnSubmit_Click(object sender, EventArgs e)
    ...
    protected void Page_Load(object sender, EventArgs e)
    ...

    protected void CodeHighlighter_PostRender(object sender, EventArgs e)
    ...
</script>

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title>InsertCode By Moozi.Net</title>

    <script src="http://www.cnblogs.com/dialog/common/fck_dialog_common.js" type="text/javascript"></script>

    <script type="text/javascript">

        var oEditor = window.parent.InnerDialogLoaded() ;

        // Gets the document DOM
        var oDOM = oEditor.FCK.EditorDocument ;

        var oActiveEl = oEditor.FCKSelection.GetSelectedElement() ;

        window.onload = function()
        {
            //window.parent.SetOkButton( false );
        }

        function Ok()
        {
            if(GetE('txtCode').value == '')
            {
                alert("代码内容不能为空！");
                return false;
            }
            oEditor.FCK.InsertHtml(document.getElementById("lblCode").innerHTML) ;
            return true ;
        }

    </script>

    <style type="text/css">
        .langType
        {
            padding-bottom: 5px;
        }
        .btnRun
        {
            padding-top: 5px;
            text-align: right;
        }
        pre
        {
            background-color: #f4f4f4;
            border-style: solid;
            border-width: 1px;
            border-color: #C0C0C0;
            font-family: Courier New, monospace;
            font-size: 10pt;
        }
    </style>
</head>
<body>
    <form id="form1" runat="server">
    <div>
        <div class="langType">
            语言类型：<asp:DropDownList ID="ddlLangType" runat="server">
            </asp:DropDownList>
            <asp:CheckBox ID="chkOutLining" Text="折叠代码" runat="server" Checked="true" />
            <asp:CheckBox ID="chkLineNum" Text="允许行号" runat="server" Checked="false" />
        </div>
        <div>
            <asp:TextBox ID="txtCode" runat="server" TextMode="multiline" Width="640px" Height="390px"></asp:TextBox>
        </div>
        <div class="btnRun">
            <asp:Button ID="btnSubmit" runat="server" Text="  转  换  " OnClick="btnSubmit_Click" />
            <pre id="pre1" style="display: none;">
            <CH:CodeHighlighter runat="server" ID="Highlighter" OnPostRender="CodeHighlighter_PostRender" />
            </pre>
            <asp:Label ID="lblCode" Style="display: none;" runat="server"></asp:Label>
        </div>
    </div>
    </form>
</body>
</html>
 

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" />
    </keywordCollection>
  </keywordLinking>
  <languages>
    <language key="Assembly" definitionPath="~/fckeditor/editor/plugins/insertcode/languages/lexers/ActiproSoftware.Assembly.xml" />

    <language key="MSIL" definitionPath="~/fckeditor/editor/plugins/insertcode/languages/lexers/ActiproSoftware.MSIL.xml" />
    <language key="Pascal" definitionPath="~/fckeditor/editor/plugins/insertcode/languages/lexers/ActiproSoftware.Pascal.xml" />

    <language key="XML" definitionPath="~/fckeditor/editor/plugins/insertcode/languages/lexers/ActiproSoftware.XML.xml" />
  </languages>
  <lineNumberMargin foreColor="Teal" paddingCharacter=" " visible="true" />
  <outlining enabled="true" imagesPath="~/fckeditor/editor/plugins/insertcode/images/" />
  <spacesInTabs count="4" />
</codeHighlighter>
 

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
