asp.net 为FCKeditor开发代码高亮插件实现代码_网页编辑器教程-查字典教程网

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

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">

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>

<title>InsertCode By Moozi.Net</title>

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>

.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>

<div>

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>

<asp:Button ID="btnSubmit" runat="server" Text=" 转换 " />

<CH:CodeHighlighter runat="server" ID="Highlighter" OnPostRender="CodeHighlighter_PostRender" />

</pre>

<asp:Label ID="lblCode" runat="server"></asp:Label>

</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>

在<system.web></system.web>后插入：

</keywordCollection>

</keywordLinking>

</languages>

</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
