fckeditor给文件(包括图片)及文件夹增加删除功能

方法一：不修改源码

1、在\fckeditor\editor\filemanager\browser\default文件夹中找到frmresourceslist.html文件，将

oListManager.GetFileRowHtml和oListManager.GetFolderRowHtml代码修改如下：

        //在文件夹后放置“删除”
        oListManager.GetFolderRowHtml = function (folderName, folderPath, folderUrl) {
            // Build the link to view the folder.
            var sLink = '<a href="#" onclick="OpenFolder(\'' + ProtectPath(folderPath) + '\');return false;">';
            return '<tr>' +
            '<td width="16">' +
                sLink +
                '<img alt="" src="images/Folder.gif" width="16" height="16" border="0"><\/a>' +
            '<\/td><td nowrap colspan="2"> ' +
                sLink +
                folderName +
                '<\/a>' +
        '<\/td><td align="right"><a href="#" onclick="DeleteFolder(\'' +
                folderName + '\',\'' +
                ProtectPath(folderUrl) +
        '\');return false;">删除</a></td><\/tr>';
        }

        //在文件后放置“删除”
        oListManager.GetFileRowHtml = function (fileName, fileUrl, fileSize) {
            var sLink = '<a href="#" onclick="OpenFile(\'' + ProtectPath(fileUrl) + '\');   return false;">';
            var sIcon = oIcons.GetIcon(fileName);
            return '<tr>' + '<td width="16">' + sLink + '<img alt="" src="images/icons/'
            + sIcon + '.gif" width="16" height="16"  border="0"> <\/a>'
            + '<\/td><td> ' + sLink + fileName
            + '<\/a> <a href="#" onclick="deleteFile(\'' +
                fileName + '\',\'' + ProtectPath(fileUrl)
            + '\');" style="color: #FF9933;"> 删除 <\/a>' + '<\/td><td align="right" nowrap> '
            + fileSize + ' KB' + '<\/td><\/tr>';
        }

2、在该文件的js中增加如下代码：

        //产生不重复的随机数
        var rn = Math.ceil(Math.random() * 1000000);
        var rnch = rn;
        function rndnum() {
            while (rn == rnch) rn = Math.ceil(Math.random() * 1000000);
            rnch = rn;
            return rn;
        }
        // 删除文件
        function deleteFile(fileName, file) {
            var xml = new ActiveXObject("MSXML2.XMLHTTP");
            if (confirm('您确定要删除“' + fileName + '”吗？')) {
                xml.open("get", "FCKdel_file.aspx?filePath=" + file + "&UD=" +
rndnum(), false);
                xml.send();
                Refresh();
                switch (xml.responseText.substring(0, 1)) {
                    case "1": alert("文件删除成功!");
                        break;
                    case "0": alert("文件删除失败!请检查文件是否存在!");
                        break;
                    case "2": alert("您不是系统管理员，无权进行操作!");
                        break;
                    default: alert("未知错误!");
                        break;
                }
            }
        }
        //删除文件夹
        function DeleteFolder(folderName, folderPath) {
            var xml = new ActiveXObject("MSXML2.XMLHTTP");
            if (confirm('您确定要删除文件夹“' + folderName + '”和里面的所有文件吗？')) {
                xml.open("get", "FCKDel_folder.aspx?folderPath=" +
escape(folderPath + folderName) + "&UD=" + rndnum(), false);
                xml.send();
                Refresh();
                switch (xml.responseText.substring(0, 1)) {
                    case "1": alert("文件夹删除成功!");
                        break;
                    case "0": alert("文件夹删除失败!请检查文件是否存在!");
                        break;
                    case "2": alert("您不是系统管理员，无权进行操作!");
                        break;
                    default: alert("未知错误!");
                        break;
                }
            }

}

继续修改文件“frmresourceslist.htm”，找到 GetFoldersAndFilesCallBack 函数中的下面这行，增加红色部分的代码：

oHtml.Append( oListManager.GetFolderRowHtml( sFolderName, sCurrentFolderPath + sFolderName + "/", sCurrentFolderUrl ) );

3、增加文件

　　在同一个目录(指frmresourceslist.html所在目录)中增加FCKdel_file.aspx，用于删除文件。代码如下：

<%@ Page Language="C#" %>

<%
    if (Request.QueryString["UD"] != null)
    {
        try
        {
            string file = Request.QueryString["filePath"].Trim();
            string filePath = Server.MapPath(file);
            if (System.IO.File.Exists(filePath))
            {
                System.IO.File.Delete(filePath);
                Response.Write("1");
            }
            else
            {
                Response.Write("0");
            }
        }
        catch
        {
            Response.Write("0");
        }
    }
    else Response.Write("2");
%>

　　在同一个目录(指frmresourceslist.html所在目录)中增加FCKDel_folder.aspx，用于删除文件夹。代码如下：

<%@ Page Language="C#" %>

<%
    if (Request.QueryString["UD"] != null)
    {
        try
        {
            string file = HttpUtility.UrlDecode(Request.QueryString["folderPath"].Trim());
            string filePath = Server.MapPath(file);
            if (System.IO.Directory.Exists(filePath))
            {
                System.IO.Directory.Delete(filePath, true);
                Response.Write("1");
            }
            else
            {
                Response.Write("0");
            }
        }
        catch
        {
            Response.Write("0");
        }
    }
    else Response.Write("2");
%>

完成，测试，成功。

方法二：修改源码(本文所针对版本：FCKeditor: 2.6.4，FCKeditor.Net: 2.6.3。)

首先下载FCKeditor控件的源码——FCKeditor.Net。

1. 打开项目 FCKeditor.Net，打开文件“FileBrowser/Connector.cs”，为 class Connector 增加如下两个成员函数：

//删除文件
        private void DelFile(XmlNode connectorNode, string resourceType, string currentFolder)
        {
            HttpContext hc = HttpContext.Current;
            string file = hc.Server.MapPath(HttpUtility.UrlDecode(hc.Request["FileUrl"], System.Text.Encoding.UTF8));
            if (System.IO.File.Exists(file))
                System.IO.File.Delete(file);
            else
                hc.Response.Write(@"<error number=""1"" originaldescription=""unable to locate file"">");
        }

        //删除文件夹
        private void DelFolder(XmlNode connectorNode, string resourceType, string currentFolder)
        {
            HttpContext hc = HttpContext.Current;
            string folder = hc.Server.MapPath(HttpUtility.UrlDecode(hc.Request["FolderName"], System.Text.Encoding.UTF8));
            if (System.IO.Directory.Exists(folder))
                System.IO.Directory.Delete(folder, true);
            else
                hc.Response.Write(@"<error number=""2"" originaldescription=""unable to locate folder"">");
        }

2. 在文件“Connector.cs”中找到 OnLoad 函数，在 switch 部分增加以下红色代码：

            // Execute the required command.
            switch (sCommand)
            {
                case "GetFolders":
                    this.GetFolders(oConnectorNode, sResourceType, sCurrentFolder);
                    break;
                case "GetFoldersAndFiles":
                    this.GetFolders(oConnectorNode, sResourceType, sCurrentFolder);
                    this.GetFiles(oConnectorNode, sResourceType, sCurrentFolder);
                    break;
                case "CreateFolder":
                    this.CreateFolder(oConnectorNode, sResourceType, sCurrentFolder);
                    break;
                case "DelFile":
                    this.DelFile(oConnectorNode, sResourceType, sCurrentFolder);
                    break;
                case "DelFolder":
                    this.DelFolder(oConnectorNode, sResourceType, sCurrentFolder);
                    break;
                default:
                    XmlResponseHandler.SendError(Response, 1, "Command is not allowed");
                    break;
            }

3. 编译 FCKeditor.net 并关闭该项目。将生成的 FredCK.FCKeditorV2.dll 拷贝出来用于Web项目的引用。

4. 建立 C# 测试项目，并在其中部署 FCKeditor 2.6.4（使用第 3 步生成的 FredCK.FCKeditorV2.dll）。

5. 打开“fckeditor/editor/filemanager/browser/default/frmresourceslist.htm”，修改以下两个函数

oListManager.GetFolderRowHtml = function( folderName, folderPath, folderUrl )
{
  // Build the link to view the folder.
  var sLink = '<a href="#" onclick="OpenFolder(\'' + ProtectPath(folderPath) +
'\');return false;">';

  return '<tr>' +
    '<td width="16">' +
      sLink +
      '<img alt="" src="images/Folder.gif" width="16" height="16" border="0"><\/a>' +
    '<\/td><td nowrap colspan="2"> ' +
      sLink +
      folderName +
      '<\/a>' +
    '<\/td><td align="right"><a href="#" onclick="DelFolder(\''+folderName+'
\',\''+ ProtectPath(folderUrl) + '\');return false;">删除</a></td><\/tr>';
}

oListManager.GetFileRowHtml = function( fileName, fileUrl, fileSize )
{
  // Build the link to view the folder.
  var sLink = '<a href="#" onclick="OpenFile(\'' + ProtectPath(fileUrl) +
'\');return false;">' ;

  // Get the file icon.
  var sIcon = oIcons.GetIcon( fileName ) ;

  return '<tr>' +
    '<td width="16">' +
      sLink +
      '<img alt="" src="images/icons/' + sIcon + '.gif" width="16" height="16" border="0"><\/a>' +
    '<\/td><td> ' +
      sLink +
      fileName +
      '<\/a>' +
    '<\/td><td align="right" nowrap> ' +
      fileSize +
      ' KB' +
    '<\/td><td align="right"><a href="#" onclick="DelFile(\''+fileName+'\',\'' +
ProtectPath(fileUrl) + '\');return false;">删除</a></td><\/tr>';
}

6. 继续修改文件“frmresourceslist.htm”，在 OpenFile 函数后面增加以下两个函数：

function DelFile( fileName, fileUrl )
{
  if (confirm('您确定要删除文件“' + fileName + '”吗？'))
    oConnector.SendCommand("DelFile", "FileUrl=" + escape(fileUrl), Refresh);
}

function DelFolder( folderName, folderPath )
{
  if (confirm('您确定要删除文件夹“' + folderName + '”和里面的所有文件吗？'))
    oConnector.SendCommand("DelFolder", "FolderName=" + escape(folderPath + folderName), Refresh);
}

7. 继续修改文件“frmresourceslist.htm”，找到 GetFoldersAndFilesCallBack 函数中的下面这行，增加红色部分的代码：

oHtml.Append( oListManager.GetFolderRowHtml( sFolderName, sCurrentFolderPath + sFolderName + "/", sCurrentFolderUrl ) );

至此，删除功能增加完毕。
