  • asp.net 为FCKeditor开发代码高亮插件实现代码

    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 
    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 http://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新建的话一定要单文件，不要代码分离方式。
    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" %> 
    <!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) 
    ...{ 
    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(" ", " ").Replace("\n", "<br />"); 
    Response.Write("<scr" + "ipt>window.parent.SetOkButton( true );</scr" + "ipt>"); 
    } 
    } 
    </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- 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>

    <outlining enabled="true" imagesPath="~/fckeditor/editor/plugins/insertcode/images/" />

    </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
