ckeditor in jsp image upload feature to increase

ckeditor ckfinder can be achieved with the image upload function, but only php and asp support, a few days to find information, and finally succeeded in jsp also to achieve this functionality.

First of all, completely generated in the editor after the call addUploadButton (editor) function, the incoming editor variable, suggested CKEDITOR.replace used directly after.

function addUploadButton (editor) (
CKEDITOR.on ('dialogDefinition', function (ev) (

var dialogName = ev.data.name;

var dialogDefinition = ev.data.definition;

if (dialogName == 'image') (

var infoTab = dialogDefinition.getContents ('info');

infoTab.add ((

type: 'button',

id: 'upload_image',

align: 'center',

label: 'Upload'

onClick: function (evt) (

var thisDialog = this.getDialog ();

var txtUrlObj = thisDialog.getContentElement ('info', 'txtUrl');

var txtUrlId = txtUrlObj.getInputElement ().$. id;

addUploadImage (txtUrlId);

)

), 'Browse'); / / place front of the browser button

)

));

)
function addUploadImage (theURLElementId) (

var uploadUrl = "upload.jsp"; / / This is my own deal with file / image upload page URL

var imgUrl = window.showModalDialog (uploadUrl);

/ / After the upload through the js code window.returnValue =... image url can be returned to the imgUrl variable.

var urlObj = document.getElementById (theURLElementId);

urlObj.value = imgUrl;
/ / Alert (urlObj.value);
/ / UrlObj.fireEvent ("onchange"); / / trigger the url text box onchange event to preview image
/ / UrlObj.fireEvent ("onchange");
/ / UrlObj.onchange ();

/ / The following only supports firefox
var evt = document.createEvent ('HTMLEvents');
evt.initEvent ('change', true, true);
urlObj.dispatchEvent (evt);

)

There must be reminded to note that different browsers is not the same event-driven, the place cards had me for a long time, because the reason I use firefox debugging, urlObj.fireEvent ("onchange"); phrase code is not working for .
addUploadImage function specify file upload page URL, and then in a modal window to open this page, handling file uploads. The end result is the image uploaded on the server's URL address is returned to a variable imgUrl. Last assignment to pass this variable entered the picture URL text box. Onchange event manually trigger the final look, so you can see in the image dialog in the preview image.

Jsp page to upload the following:

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
  <head>
    <base href="<%=basePath%>">

  <body>

    <form name="form1" method="post" action="imgUpload.do" enctype="multipart/form-data">

            <input type="hidden" value="${requestScope.pagePath}" name="pagePath" />
    </form>
    <script type="text/javascript">
            var _pagePath = document.getElementById("_pagePath").value;

                //alert(_pagePath);
            if(null!=_pagePath  && ""!=_pagePath){

               window.returnValue=_pagePath; 

               window.close(); 

            }
        </script>
  </body>
</html>

From the background of the treatment I used to write struts1.2
UploadForm:

package com.newsManage_10.struts.form;

import org.apache.struts.action.ActionForm;
import org.apache.struts.upload.FormFile;

public class UploadForm extends ActionForm {

        private static final long serialVersionUID = 1L;
        private FormFile imgFile;

        public FormFile getImgFile() {
           return imgFile;
        }

        public void setImgFile(FormFile imgFile) {
           this.imgFile = imgFile;
        }

        }

ImgUploadAction:

}

the relevant parts of the configuration file struts as I type with a spring so the content is different

<action
      name="UploadForm"
      path="/imgUpload"
      scope="request"
      type="org.springframework.web.struts.DelegatingActionProxy"
      parameter="method">
            <forward name="success" path="/upload.jsp" />
    </action>

<form-bean name="UploadForm" type="com.newsManage_10.struts.form.UploadForm" />
