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。
