Java中JSP、JS调用fckeditor的两种方法

在java开发中用得比较多的文本编辑器一般采用fckeditor。

现就fckeditor在JSP中的调用归纳如下：

<%

String path = request.getContextPath();

String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";

%>

1、JSP页面在调用：

1）首先在web.xml中做简单的配置，配置文件内容如下，直接copy到web.xml即可：

<servlet-name>Connector</servlet-name>

<servlet-class>com.fredck.FCKeditor.connector.ConnectorServlet</servlet-class>

<init-param>

<param-name>baseDir</param-name>

<param-value>/UserFiles/</param-value>

</init-param>

<init-param>

<param-name>debug</param-name>

<param-value>false</param-value>

</init-param>

<load-on-startup>1</load-on-startup>

</servlet>

<servlet-name>SimpleUploader</servlet-name>

<servlet-class>com.fredck.FCKeditor.uploader.SimpleUploaderServlet</servlet-class>

<init-param>

<param-name>baseDir</param-name>

<param-value>/UserFiles/</param-value>

</init-param>

<init-param>

<param-name>debug</param-name>

<param-value>false</param-value>

</init-param>

<init-param>

<param-name>enabled</param-name>

<param-value>true</param-value>

</init-param>

<init-param>

<param-name>AllowedExtensionsFile</param-name>

<param-value></param-value>

</init-param>

<init-param>

<param-name>DeniedExtensionsFile</param-name>

<param-value>php|php3|php5|phtml|asp|aspx|ascx|jsp|cfm|cfc|pl|bat|exe|dll|reg|cgi</param-value>

</init-param>

<init-param>

<param-name>AllowedExtensionsImage</param-name>

<param-value>jpg|gif|jpeg|png|bmp</param-value>

</init-param>

<init-param>

<param-name>DeniedExtensionsImage</param-name>

<param-value></param-value>

</init-param>

<init-param>

<param-name>AllowedExtensionsFlash</param-name>

<param-value>swf|fla</param-value>

</init-param>

<init-param>

<param-name>DeniedExtensionsFlash</param-name>

<param-value></param-value>

</init-param>

<load-on-startup>1</load-on-startup>

</servlet>

<servlet-mapping>

<servlet-name>Connector</servlet-name>

<url-pattern>/include/fckeditor/editor/filemanager/browser/default/connectors/jsp/connector</url-pattern>

</servlet-mapping>

<servlet-mapping>

<servlet-name>SimpleUploader</servlet-name>

<url-pattern>/include/fckeditor/editor/filemanager/upload/simpleuploader</url-pattern>

</servlet-mapping>

<taglib-uri>/include/fckeditor</taglib-uri>

<taglib-location>/WEB-INF/FCKeditor.tld</taglib-location>

</taglib>

2）JSP页面要引入FCKeditor.tld这个文件，该文件放在WEB-INF文件夹下，页面引入代码如下：

<%@ taglib uri="/WEB-INF/FCKeditor.tld" prefix="fck" %>

3）实现代码如下：

<tr>

<fck:editor id="f_content" basePath="/dpsafe/include/fckeditor/"

height="500"

width="100%"

skinPath="/dpsafe/include/fckeditor/editor/skins/default/"

toolbarSet="Default"

imageBrowserURL="/dpsafe/include/fckeditor/editor/filemanager/browser/default/browser.html?Type=Image&Connector=connectors/jsp/connector"

linkBrowserURL="/dpsafe/include/fckeditor/editor/filemanager/browser/default/browser.html?Connector=connectors/jsp/connector"

flashBrowserURL="/dpsafe/include/fckeditor/editor/filemanager/browser/default/browser.html?Type=Flash&Connector=connectors/jsp/connector"

imageUploadURL="/dpsafe/include/fckeditor/editor/filemanager/upload/simpleuploader?Type=Image"

linkUploadURL="/dpsafe/include/fckeditor/editor/filemanager/upload/simpleuploader?Type=File"

flashUploadURL="/dpsafe/include/fckeditor/editor/filemanager/upload/simpleuploader?Type=Flash">

</fck:editor>

</td>

</tr>

我将fckeditor单独入在一个公用的include文件夹中，以便任何要用到该编辑器的页面都能够引用它，节省空间，维护方便。

到此fckeditor编辑器也就能够使用了。

2、在页面写这么多东西，感觉太复杂了一点，要写配置还要引用文件；用JS调用就相对要简单些，具体介绍如下：

1）引入fckeditor.js文件，具体代码如下：

2) 页面具体的代码调用如下：

<tr>

<!--

var sBasePath = "<%=basePath%>/include/fckeditor/";

var oFCKeditor = new FCKeditor( 'f_content' ) ;

oFCKeditor.BasePath = sBasePath ;

oFCKeditor.Height = 500 ;

oFCKeditor.Create() ; //调用它的create()方法来直接在JSP嵌入FCKeditor编辑器

//-->

</script>

</td>

</tr>

另一种调用FCKeditor编辑器的方法的简单区别是：

<td>

<textarea id="f_content" name="f_content" style="WIDTH: 100%; HEIGHT: 400px">input</textarea>

var sBasePath = "<%=basePath%>/include/fckeditor/";

var oFCKeditor = new FCKeditor( 'f_content' ) ;

oFCKeditor.BasePath = sBasePath ;

oFCKeditor.Height = 500 ;

oFCKeditor.ReplaceTextarea(); //替换文本域

</script>

</td>

3、修改页面如何实现，只需修改几个部分即可，具体如下：

1）JSP修改页面只需在增加页面的基础上加一句代码：

<fck:editor id="f_content" basePath="/dpsafe/include/fckeditor/"

height="500"

width="100%"

skinPath="/dpsafe/include/fckeditor/editor/skins/default/"

toolbarSet="Default"

imageBrowserURL="/dpsafe/include/fckeditor/editor/filemanager/browser/default/browser.html?Type=Image&Connector=connectors/jsp/connector"

linkBrowserURL="/dpsafe/include/fckeditor/editor/filemanager/browser/default/browser.html?Connector=connectors/jsp/connector"

flashBrowserURL="/dpsafe/include/fckeditor/editor/filemanager/browser/default/browser.html?Type=Flash&Connector=connectors/jsp/connector"

imageUploadURL="/dpsafe/include/fckeditor/editor/filemanager/upload/simpleuploader?Type=Image"

linkUploadURL="/dpsafe/include/fckeditor/editor/filemanager/upload/simpleuploader?Type=File"

flashUploadURL="/dpsafe/include/fckeditor/editor/filemanager/upload/simpleuploader?Type=Flash">

<%=pubDTO.getContent() %>

</fck:editor>

2）JS修改方法如下：

<tr>

var sBasePath = "<%=basePath%>/include/fckeditor/";

var oFCKeditor = new FCKeditor( 'f_content' ) ;

oFCKeditor.BasePath = sBasePath ;

oFCKeditor.Height = 500 ;

oFCKeditor.Value = '<%=f_content%>' ;

oFCKeditor.Create() ;

//-->

</script>

</td>

</tr>
