我的笔记

FCKeditor资料下载及介绍

官方网站：http://www.fckeditor.net

1.下载FCKeditor *.*.*

2.下载fckeditor-java-*.*.*-bin.zip

3.下载fckeditor-java-demo-*.*.*.war （可作为参考)

demo的查看、doc文档的查看

下载的说明，涉及java还得下个包 war工程的查看

安装与通过JavaScript调用FCKeditor的两种方法

部署：拷贝到webroot下

fckeditor的调用方式：

1.通过javascript调用

2.在jsp中通过自定义标签调用

参考方式：附带的例子 samples里文档

通过javascript调用

方法一：

<script type="text/javascript" src="fckeditor/fckeditor.js"></script>
   <script type="text/javascript"><!-- 编辑器创建 -->
      var oFCKeditor = new FCKeditor("FCKeditor1");
      oFCKeditor.BasePath = "/test/fckeditor/";<!-- fckedior绝对路径，/结尾 -->
      oFCKeditor.Create();
   </script>

　　方法二：

<script type="text/javascript" src="fckeditor/fckeditor.js"></script>
      <head></head>里添加
    <script type="text/javascript">
       window.onload=function(){
       var oFCKeditor = new FCKeditor("MyTextarea");<!-- 下面指定 -->
       oFCKeditor.BasePath = "fckeditor/";<!-- fckedior相对路径，/结尾 -->
       oFCKeditor.ReplaceTextarea();
     }
     < /script>
      <body></body>里添加
    <textarea id="MyTextarea" name="MyTextarea">this is</textarea>

方法三：

注意：BasePath要正确的设置 BasePath一定要以“/”结尾

fckeditor对象属性

Width 默认100%

Height 默认200

ToolbarSet 默认default

BasePath 默认/fckeditor/

构造器

var FCKeditor = function(instanceName,width,height,toolbarSet,value)

instanceName为编辑器输出的textarea元素的name属性值，必须指定

参数会赋值给同名属性

在jsp中通过自定义标签调用FCKeditor

参考演示工程帮助文档 jar文件拷贝

步骤：拷贝jar文件

<%@ taglib uri="http://java.fckeditor.net" prefix="FCK" %>

<FCK:editor instanceName="myEditor" basePath="/fckeditor" value="haha"></FCK:editor>

注意：basePath要以“/”开头，/代表当前工程路径一定要设置value属性的值，并且值不能为空字符串

配置_使用配置文件

webroot下创建myconfig.js文件

FCKConfig.AutoDetectLanguage=false; 自动检测语言

FCKConfig.DefaultLanguage="fr";

在默认的配置文件里

一、FCKConfig.CustomConfigurationsPath='/test/myconfig.js';

二、在创建编辑器时指定下 oFCKeditor.Config["CustomConfigurationsPath"]="/test/myconfig.js"; 只对当前有效

配置FCKeditor三种方式

直接修改主配置文件 fckconfig.js

定义单独的配置文件(只需用写需要修改的配置项)

在页面的调用代码中对FCKeditor的实例进行配置

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

系统会自动侦测并运用适当的界面语言(默认，可以修改)

不能删除主配置文件fckconfig.js

修改配置后要清空浏览器缓存,以免影响结果 (或访问时强制刷新也可以) IE:Ctrl+F5 Firefox:Shift+Ctrl+R

配置_一般需要修改的配置

一般需要修改的配置

自定义ToolbarSet,去掉一些功能

加上几种常用的字体

修改"回车"和"Shift+回车"的换行行为

修改编辑区的样式

更换表情图片

自定义ToolbarSet,去掉一些功能

先自定义工具集再引用该工具集

关于自定义工具集选择的工具看 '-'代表分隔符'|' '/'代表换行符

加上几种常用的字体

FCKConfig.FontNames = '实体；楷体_GB2312;黑体;隶书;Times New Roman;Arial';

修改"回车"和"Shift+回车"的换行行为

FCKConfig.EnterMode = 'br'; // p | div | br

FCKConfig.ShiftEnterMode = 'p';

修改编辑区的样式

文件路径 FCKConfig.basePath下 alert()下就知道在哪了

配置_更换表情图片

配置选项

FCKConfig.SmileyPath = ''; //文件路径

FCKConfig.SmileyImages = ['','']; //路径下的图片名称

FCKConfig.SmileyColumns = 8; //每行显示数量

FCKConfig.SmileyWindowWidth = 320; //窗体宽度

FCKConfig.SmileyWindowHeight =210; //窗体高度

单个添加更换或整个文件夹更换想添加滚动条，查看窗体的文件进行修改

FCKConfig.CustomConfigurationsPath='/test/myconfig.js';

工程不确定，应该修改为 FCKConfig.CustomConfigurationsPath=FCKConfig.EditorPath+'myconfig.js';

注意：自定义的配置文件要使用UTF-8编码保存

FCKConfig.BasePath和调用fckeditor时指定的 BasePath(FCKeditor.BasePath)不是同一个，其值也不一样

文件上传_基本使用

使用看java关联的文档

步骤在web.xml文件添加一个servlet

     <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>

在classpath下新建fckeditor.properties //名字路径不能改变

里面内容

connector.userActionImpl=net.fckeditor.requestcycle.impl.UserActionImpl

文件上传_问题一_上传中文名的文件会出现乱码

使用文件上传会遇到下面问题

上传中文名的文件会出现乱码

创建中文名的目录时会出现乱码

引用的中文名字的图片不能正常显示解决：写个servlet把post方法中setHeaderEncoding("utf-8");

                                ur = new UploadResponse(UploadResponse.SC_INVALID_EXTENSION);
                            }
                        } else
                            uplFile.write(pathToSave);

                    }
                } catch (Exception e) {
                    ur = new UploadResponse(UploadResponse.SC_SECURITY_ERROR);
                }
            }

        }

        out.print(ur);
        out.flush();
        out.close();

        logger.debug("Exiting Connector#doPost");
    }

}

问题二_创建中文名的目录时会出现乱码

解决：在servlet的get方法，当request.getParameter("");之后重新编码

问题三_引用的中文名字的图片不能正常显示

解决：

方案一：修改tomcat的servlet.xml在<Connector>添加URIEncoding="UTF-8" 不推荐使用，因为将对创建中文文件夹有影响

方案二：避免使用中文名称保存图片，在servlet修改，采用UUID随机设置名称

文件上传允许上传的文件类型

a.控制允许上传的文件类型

FCKeditor把文件的上传分成4类

File

Image

Flash

Media

b.设置允许上传的文件扩展名列表禁止上传的文件扩展名列表只能配置一项

c.修改时除了media客户端不用设置，其它的客户端和服务器端都必须设置，且设置相同

文件上传允许上传的文件的大小

步骤：在服务器端的servlet中，在保存文件之前先判断一下文件的大小，

如果超出限制，就传递一个自定义的错误码，并且不再保存文件修改对应界面的回调函数，增加对这个自定义的错误码的处理

在表单中使用FCKeditor a.一般都放在表单中提交，只要放在<form></form>中 b.通过fckeditor提交的中文内容，在服务器端得到的为乱码的解决
