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​​​​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: 

<%@ 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= 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 ; 

<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> 

<asp:TextBox ID="txtCode" runat="server" TextMode="multiline" Width="640px" Height="390px"></asp:TextBox> 

<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> 

</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>

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
