fckeditor的用法，如何获得编辑器中的内容（转自http://suichunyu1987.blog.163.com/blog/static/87309653200981032351210/）
配置FCKeditor
§Fckdeitor/editor/fckconfig.js为fckdeitor的主要配置文件包含所有可配置的信息
§1.可以直接修改主配置文件fckdeitor.js
§2.定义单独的配置文件覆盖fckdeitor.js文件
首先创建自己的一个JavaScript文件
配置好自己的设置后在fckcofing.js中指定自定义的配置文件
具体配置如下
FCKConfig.Custom
ConfigurationPath=‘/工程名/配置文件名’
§3.在页面中创建fckeditor时指定配置文件（只对当前实例有效）oFCKeditor.config [“CustomConfigurationsPath”]=“/工程名/配置文件名”
配置加载顺序
1.加载主配置文件fckconfig.js
2.加载自定义的配置文件（如果有），覆盖相同的配置项
3.使用对实例的配置覆盖相同的配置项（只对当前实例有效）
提示
1.系统会自动检测并运用适当的界面语言
2.不能删除主配置文件fckconfig.js
3.修改配置后要清空浏览器缓存，以免影响结果
§自定义toolbarSet
1.直接修改工具集或应用自定义的工具集
2. 在配置文件中自定义工具集
单引号引用的短语为一个功能‘—’表示一个分析符‘/’表示一个换行 对照显示效果进行修改
使用方法在引用fckeditor时添加toolbarSet属性 例子：oFCKeditor.ToolbarSet=“自定义工具集名”
§加上常用字体
1.在主配置文件中找到FCKConfig.FontNames选项并复制到自定义的配置文件中
2.配置自己的字体：不同的字体之间用‘；’分隔 并且需要将配置文件的编码方式改为“utf-8”
§修改回车和shift+回车的换行行为
在主配置文件中找到
FCKConfig.EnterMode=‘p’;
FCKConfig.ShiftEnterMode=‘br’;
复制到自定义的配置文件中。改为：
FCKConfig.EnterMode=‘br’;
FCKConfig.ShiftEnterMode=‘p’;
§修改编辑区的样式文件
在主配置文件中找到
FCKConfig.EditorAreaCSS=FCKConfig.BasePath+’css/fck_editorarea.css’;
找到css对其进行修改
§更换表情图片
§在主配置文件中找到相应的配置信息
§找到fck_smiley.html在onload方法中
§Dialog.SetAutoSize(true)自动调整窗口大小
如果要显示滚动条
在<body style=“overflow:hidden”>
Visible:默认值。不剪切内容也不添加滚动条、
Auto：在必需时对象内容才会被剪切或显示滚动条
Hidden：不显示超过对象尺寸的内容
Scroll：总是显示滚动条
自定义配置文件的路径设置
§FCKConfing.EditorPath+”myconfig.js”
§FCKConfing.EditorPath为fckeditor/editor的路径
myconfig.js为自定义的配置文件
文件上传
§在工程的web.xml中配置servlet
§第一步：
<servlet>
<servlet-name>Connector</servlet-name>
<servlet-class> net.fckeditor.connector.ConnectorServlet </servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>Connector</servlet-name>
<url-pattern> /fckeditor/editor/filemanager/connectors/* </url-pattern>
</servlet-mapping>
§第二步：
在classpath下创建一个配置文件文件名为fckeditor.properties
connector.userActionImpl=net.fckeditor.requestcycle.impl.UserActionImpl
无法使用中文信息
修改此问题需要修改FCKeditor上传文件的servlet的源码
无法上传中文图片
在servlet的post方法中设置
upload.setHeaderEncoding("utf-8");
无法引用中文文件
改变上传文件的名称
filename=UUID.randomUUID ().toString()+"."+extension;
无法创建中文文件夹
修改方法：
在get中进行转码。
newFolderStr =new String(newFolderStr.getBytes("iso8859-1"),"utf-8");
一个修改好的servlet：

test.sui <!--改为自己定义的servlet名 -->
