Ckeditor 的使用

在做网页编辑时，我们选用Ckeditor 。来编辑。

有点麻烦，在这里做一个笔记，用的时候，把代码拷下来就直接用，其中处理了，上传图片，视频，还有中文乱码等问题。

首先下载ckeditor 和 ckfinder 的 rar 包，解压放到WebRoot 下，

项目，结构图如下：

然后，在index.jsp 页面中 导入 这两个文件。

<script type="text/javascript" src="ckeditor/ckeditor.js"></script>
<script type="text/javascript" src="ckfinder/ckfinder.js"></script>
<script type="text/javascript" src="js/jquery-1.3.2.min.js"></script>

新建一个config.xml 放到WEB-INF 下内容如下：

<config>
	<enabled>true</enabled>
	<baseDir></baseDir>

修改web.xml

	</welcome-file-list>
</web-app>

然后，看一下index.jsp 页面的内容

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<script type="text/javascript" src="ckeditor/ckeditor.js"></script>
<script type="text/javascript" src="ckfinder/ckfinder.js"></script>
<script type="text/javascript" src="js/jquery-1.3.2.min.js"></script>
<title>CkeditorAndckfinderForJava</title>
<script type="text/javascript">
	function sub(){
		var editor1 = CKEDITOR.instances.editor1.getData();//取得textarea的值
		alert("q" + editor1 + "q");
		var title= $("#title").val();
		alert(title);
        document.myform.action="myPicture.do?editor1="+editor1+"&title"+title;
	    document.myform.submit();
	
	}
        $(function () {
            //处理CKEDITOR的值 处理获取图片的地址
            function CKupdate() {
                 for (instance in CKEDITOR.instances)
                     CKEDITOR.instances[instance].updateElement();
            }
            
        })

    </script>
</head>
<body>
<form name="form" id="myform"  method="post" >
 <table>
   <tr>
    <td>标题：</td>
    <td><input type="text" id="title" name="title"></td>
   </tr>
   <tr> 
    <td colspan="2">
    <textarea id="editor1" name="editor1" class="ckeditor" rows="10" cols="80"> </textarea>
    </td>
   </tr>
 </table>
<input type="button" id="subAjax" value="提交" onclick="sub();" />
</form>
</body>
</html>

注：需要定义 成UTF-8 的页面。

看一下后台获取数据的代码 MyPicture.java。

package com.etor.text;

import java.io.IOException;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class MyPicture extends HttpServlet {
 
//	 <!--   <%=request.getParameter("content")%> --> 
	private static final long serialVersionUID = -5086295779218715999L;


	@Override
	protected void doGet(HttpServletRequest req, HttpServletResponse resp)
			throws ServletException, IOException {
		this.doPost(req, resp);
	}

 
	@Override
	protected void doPost(HttpServletRequest req, HttpServletResponse resp)
			throws ServletException, IOException {  
		String content = req.getParameter("editor1");
		content = new String(content.getBytes("ISO-8859-1"),"UTF-8");
		String title = req.getParameter("title");//title
		title = new String(title.getBytes("ISO-8859-1"),"UTF-8");

		System.out.println("title:"+title);
		System.out.println(content);
		req.setAttribute("contentMy",content);
	   req.getRequestDispatcher("/result.jsp").forward(req, resp);
	}

	
}

看一下效果图：

最后，到后台 到跳转到result.jsp

有时候，我们需要自己配置一下，ckeditor 的工具栏，配置在 ckeditor/config.xml ，可以修改，需要哪些工具栏。

有时候，我们上传图片，视频，文件，不需要 让他浏览服务器上的其他文件内容，这个时候，我们需要把浏览服务器 的功能 去掉，

请参看 http://blog.163.com/zjc_8886/blog/static/2408175201011222590967/ 

我测试过，好使。

有时候，文件名是中文件的会上传时，打不开图片或是图片出现一个X ，不支持中文图片名，需要设置一下服务器参见。

我测试过，不太好使。在后台中文图片 名 获取不到，会出现 ??11.jpg 这样的格式。
