比较不错的修改FCKEditor的修改方法

  由于项目需要,近期仔细研究了FCKEditor。发现一下bug,以及缺少的一些东西。

  一、防止连续文本导致出现滚动条

  FCKEditor编辑器使用Iframe来处理编辑器内容,可惜不支持文本换行,假如你连续输入一段英文或数字等,将会出现滚动条,这时我们需要给其增加word-wrap样式为break-word;

  添加方式有很多,我选择最便捷的修改方式:具体做法是修改fckeditor.html文件,给<iframe id="eEditorArea" 增加事件 onload="window.frames['eEditorArea'].document.body.style.wordWrap='break-word'"

  二、增加Media以及Realplay按钮

  此项工作相对庞大,要修改很多js文件,以及一些图片和样式文件。

  a.准备图片:FCKeditor\editor\css\images下面,添加fck_medialogo.gif和fck_realplaylogo.gif,大小随意,作为背景居中显示的。

  FCKeditor\editor\skins\default\toolbar\增加media.gif和realplay.gif,其他皮肤类推。

  b.修改css:给FCKeditor\editor\css\fck_internal.css增加

  .FCK__Media

  {

  border: darkgray 1px solid;

  background-position: center center;

  background-image: url(images/fck_medialogo.gif);

  background-repeat: no-repeat;

  width: 80px ;

  height: 80px ;

  }

  .FCK__Realplay

  {

  border: darkgray 1px solid;

  background-position: center center;

  background-image: url(images/fck_realplaylogo.JPG);

  background-repeat: no-repeat;

  width: 80px ;

  height: 80px ;

  }

  c。修改js,主要以realplay做示例

  FCKeditor\editor\js\fckeditorcode_ie_1.js,在FCKDocumentProcessors.addItem(FCKFlashProcessor);后面增加

  // Realplay begin

  var FCKRealplayProcessor=new Object();

  FCKRealplayProcessor.ProcessDocument=function(A){

  var B=A.getElementsByTagName('EMBED');

  var C;

  var i=B.length-1;

  while (i>=0&&(C=B[i--])){

  if (C.src.endsWith('.rm',true) || C.src.endsWith('.ram',true) || C.src.endsWith('.ra',true))

  {var D=FCKDocumentProcessors_CreateFakeImage('FCK__Realplay',C.cloneNode(true));

  D.setAttribute('_fckRealplay','true',0);

  FCKRealplayProcessor.RefreshView(D,C);

  C.parentNode.insertBefore(D,C);

  C.parentNode.removeChild(C);

  };

  };

  };

  FCKRealplayProcessor.RefreshView=function(A,B){

  if (B.width>0) A.style.width=FCKTools.ConvertHtmlSizeToStyle(B.width);

  if (B.height>0) A.style.height=FCKTools.ConvertHtmlSizeToStyle(B.height);

  };

  FCKDocumentProcessors.addItem(FCKRealplayProcessor);

  // Realplay end

  var FCKMediaProcessor=new Object();

  FCKMediaProcessor.ProcessDocument=function(A)

  {

  var B=A.getElementsByTagName('EMBED');

  var C;

  var i=B.length-1;

  while (i>=0&&(C=B[i--]))

  {

  if (C.src.endsWith('.avi',true) || C.src.endsWith('.mpg',true) || C.src.endsWith('.mpeg',true))

  {

  var D=FCKDocumentProcessors_CreateFakeImage('FCK__Media',C.cloneNode(true));

  D.setAttribute('_fckmedia','true',0);FCKMediaProcessor.RefreshView(D,C);

  C.parentNode.insertBefore(D,C);C.parentNode.removeChild(C);

  };

  };

  };

  FCKMediaProcessor.RefreshView=function(A,B)

  {

  if (B.width>0) A.style.width=FCKTools.ConvertHtmlSizeToStyle(B.width);

  if (B.height>0) A.style.height=FCKTools.ConvertHtmlSizeToStyle(B.height);

  };

  FCKDocumentProcessors.addItem(FCKMediaProcessor);

  然后修改FCK.GetRealElement方法为下面代码,该方法为处理编辑器中width和height的调整

  FCK.GetRealElement=function(A){

  var e=FCKTempBin.Elements[A.getAttribute('_fckrealelement')];

  if (A.getAttribute('_fckflash')|| A.getAttribute('_fckrealplay') || A.getAttribute('_fckmedia')){

  if (A.style.width.length>0) e.width=FCKTools.ConvertStyleSizeToHtml(A.style.width);

  if (A.style.height.length>0) e.height=FCKTools.ConvertStyleSizeToHtml(A.style.height);

  };

  return e;};

  ----------

  FCKeditor\editor\js\fckeditorcode_ie_2.js

  FCKCommands.GetCommand方法增加

  case 'Media':B=new FCKDialogCommand('Media',FCKLang.DlgMediaTitle,'dialog/fck_Media.html',450,400);

  break;

  case 'Realplay':B=new FCKDialogCommand('Realplay',FCKLang.DlgMediaTitle,'dialog/fck_Realplay.html',450,400);

  break;

  FCKToolbarItems.GetItem方法增加

  case 'Media':B=new FCKToolbarButton('Media',FCKLang.InsertMediaLbl,FCKLang.InsertMedia);

  break;

  case 'Realplay':B=new FCKToolbarButton('Realplay',FCKLang.InsertRealplayLbl,FCKLang.InsertRealplay);

  break;

  FCKContextMenu._GetGroup方法增加

  case 'Media':return new FCKContextMenuGroup(true,this,'Media',FCKLang.MediaProperties,true);

  case 'Realplay':return new FCKContextMenuGroup(true,this,'Realplay',FCKLang.RealplayProperties,true);   // truly

  FCKContextMenu.RefreshState方法增加

  if (this.Groups['Media'])   this.Groups['Media'].SetVisible(B=='IMG'&&A.getAttribute('_fckmedia'));

  if (this.Groups['Realplay'])  this.Groups['Realplay'].SetVisible(B=='IMG'&&A.getAttribute('_fckrealplay'));

  然后要增加'dialog/fck_Media.html'和'dialog/fck_Realplay.html'页面,具体我懒得再写了,自己到我的源码下载里看,我是在2。1的基础上改的,2.2要做一些调整!

  fckconfig.js也有较多调整,但是这个文件非常简单,自己去看我的源码吧。

  然后就是lang目录中对常量的定义,搜索一下就很容易得到,没什么可讲。

  在然后就可以了,:)。

  三、添加删除按钮列,类似sina的blog中的编辑控件

  四、修改上传路径

  默认是根目录/UserFiles,有多种方式进行修改,先看一下它的源码:

  protected string UserFilesPath

  {

  get

  {

  if ( sUserFilesPath == null )

  {

  // Try to get from the "Application".

  sUserFilesPath = (string)Application["FCKeditor:UserFilesPath"] ;

  // Try to get from the "Session".

  if ( sUserFilesPath == null || sUserFilesPath.Length == 0 )

  {

  sUserFilesPath = (string)Session["FCKeditor:UserFilesPath"] ;

  // Try to get from the Web.config file.

  if ( sUserFilesPath == null || sUserFilesPath.Length == 0 )

  {

  sUserFilesPath = System.Configuration.ConfigurationSettings.AppSettings["FCKeditor:UserFilesPath"] ;

  // Otherwise use the default value.

  if ( sUserFilesPath == null || sUserFilesPath.Length == 0 )

  sUserFilesPath = DEFAULT_USER_FILES_PATH ;

  // Try to get from the URL.

  if ( sUserFilesPath == null || sUserFilesPath.Length == 0 )

  {

  sUserFilesPath = Request.QueryString["ServerPath"] ;

  }

  }

  }

  // Check that the user path ends with slash ("/")

  if ( ! sUserFilesPath.EndsWith("/") )

  sUserFilesPath += "/" ;

  }

  return sUserFilesPath ;

  }

  }

  由此,可以在Global里或者程序任意位置(加载fckeditor前可以运行到的位置)设置Application["FCKeditor:UserFilesPath"] ,或者Session,或者Webconfig,或者action中的请求参数等。
