CKEditor和UEditor使用比较
本来项目中使用CKEditor已经做好了的富文本编辑器的功能,但是业务考虑到美观性要求换成UEditor,所以就在这里总结下
先说下使用这两个不同插件的感想,我用的ueditor是1.4.3的版本:(ueditor API)
UEditor:ueditor更注重用户体验,而且使用起来较ckeditor简单,但是ueditor在处理前后台交互时相比于ckeditor稍显麻烦
ckeditor:ckeditor不像ueditor,更多的方法需要自己去实现,但是毕竟是老牌富文本编辑器,如果之前有写过这些方法的话,集成ckeditor个人觉得还是比ueditor更方便简单。
CKEditor的使用
在jsp页面下引入ckeditor下的ckeditor.js(当然首先要引入jquery.js)
- <script type="text/javascript" src="${basePath}/js/ckeditor/ckeditor.js"></script>
//引入js后在textarea标签上添加一个richText=”true”这个属性即可
- <textarea name="wxChoiceInfo.infoTextConte" id="wxChoiceInfoInfoTextConte" richText="true" cols="110" rows="15"></textarea>
- 获取ckeditor中的内容
- Var content = CKEDITOR.instances.wxChoiceInfoInfoTextConte.getData(content);
- //初始化
- $(function() {
- //富文本字段初始化
- $("[richText]").each(function (e) {
- CKEDITOR.replace($(this).attr("id"),{
- height : 400,
- skin : 'kama',
- language : 'zh-cn',
- filebrowserImageUploadUrl:'${basePath}/wxdate/ck_upload.action?fileType=1',
- toolbar: 'ToolbarCommon',
- resize_enabled: false
- });
- });
- });
- Action配置
- <!-- FckEdit上传-->
- <action name="ck_upload" class="com.ccxe.wxdate.action.CkeditorUploadAction">
- <param name="fileSize">5120000</param> <!-- 上传文件大小 -->
- </action>
- //CkeditorUploadAction类源码
- public class CkeditorUploadAction extends ActionSupport {
- private static final long serialVersionUID = 1L;

- }

- os.close();
- }
- }
- } catch (Exception e) {
- e.printStackTrace();
- }
- }
- }
- Web.xml配置FckImageReaderServlet
- <!-- FCK -->
- <servlet>
- <servlet-name>FckReader</servlet-name>
- <servlet-class>com.***.common.file.FckImageReaderServlet</servlet-class>
- </servlet>
- <servlet-mapping>
- <servlet-name>FckReader</servlet-name>
- <url-pattern>/fckImageReader.servlet</url-pattern>
- </servlet-mapping>
再来看UEditor:
- //引入相关的js和css
- <script type="text/javascript" src="${basePath}/js/ueditor/ueditor.config.js"></script>
- <script type="text/javascript" src="${basePath}/js/ueditor/ueditor.all.js"></script>
- <link type="text/css" rel="stylesheet" href="${basePath}/js/ueditor/themes/default/css/ueditor.css">
- <form action="<s:url value="/p2p/updateIProductServices.action"/>" method="post" id="form">
- <tr id="proInvSerTr">
- <th>投资服务流程 <input type="hidden" id="hidInvestProcess" name="productServices.investSerProcess"/></th>
- <td>
- <!-- 加载编辑器的容器 -->
- <script id="container" name="content" type="text/plain">${productServices.investSerProcess}</script>
- <!-- 实例化编辑器 -->
- <script type="text/javascript">
- var ue = UE.getEditor('container');
- </script>
- </td>
- </tr>
- <input type="button" value="保存" class="ImgButton" onclick="submitForm"/>
- </form>
- <script type="text/javascript">
- function submitForm(){
- $("#hidInvestProcess").val(ue.getContent());
- $("#form").submit();
- }
</script> 这样Ueditor就完成了初始化了,为啥前面授ueditor在前后台交互上要比ckeditor复杂呢,就是因为ckeditor可以直接给textarea加上name属性,提交表单时可以直接注入,而ueditor则必须通过隐藏域传值(暂时没有想到其他的方法,当然ajax提交表单肯定肯定是可以的),所以要比ckeditor多了一步,但是ueditor已经帮我们实现了上次的方法,所以这里ueditor又比ckeditor更方便。
说了那么多,那使用ueditor怎么修改文件上次的路劲呢,在1.4.3版本下,找到ueditor\jsp\config.json文件
找到上次图片配置项的"imageUrlPrefix": "/", /* 图片访问路径前缀 */
"imagePathFormat": "upload/image/{yyyy}{mm}{dd}/{time}{rand:6}" //这里是我改过了的上传路径
注意要修改imageUrlPrefix,因为编辑器中图片显示路径是imageUrlPrefix+imagePathFormat,如果不修改imageUrlPrefix图片是不能正常显示的,imagePathFormat这个上传路径是相对于服务器的相对路径。
使用ueditor最主要的就是需要修改web.xml中得struts的过滤器了,这个项目的前台要求全部使用.html结尾,如果不修改的话,struts就会把上传的静态页面image.html当成action去处理了会报404,修改代码如下:
- <filter>
- <filter-name>struts2</filter-name>
- <filter-class>com.***.***.filter.CommonFilter</filter-class>
- <init-param>
- <param-name>config</param-name>
- <param-value>../config/struts.xml</param-value>
- </init-param>
- </filter>
- <filter-mapping>
- <filter-name>struts2</filter-name>
- <url-pattern>/*</url-pattern>
- </filter-mapping>
filter的代码
- public class CommonFilter extends StrutsPrepareAndExecuteFilter{
- @Override
- public void doFilter(ServletRequest req, ServletResponse resp,
- FilterChain chain) throws IOException, ServletException {
- HttpServletRequest request = (HttpServletRequest)req;
- String url = request.getRequestURI();
- if(url.contains("/ueditor")){
- chain.doFilter(req, resp);
- }else{
- super.doFilter(req, resp, chain);
- }
- }
- }
有什么问题,欢迎各位指正。
