1.什么是KindEditor

KindEditor 是一套开源的在线HTML编辑器,主要用于让用户在网站上获得所见即所得编辑效果,开发人员可以用 KindEditor 把传统的多行文本输入框(textarea)替换为可视化的富文本输入框。 KindEditor 使用 JavaScript 编写,可以无缝地与 Java、、PHP、ASP 等程序集成,比较适合在 CMS、商城、论坛、博客、Wiki、电子邮件等互联网应用上使用。

2.前期准备

文件结构:

asp:与asp结合的示例代码

asp:与asp结合的示例代码

attached:上传文件的根目录,可在相关的代码中修改

examples:功能演示的示例代码

jsp:与jsp结合的示例代码

lang:语言包

php:与php结合的示例代码

plugins:控件的功能代码的实现

kindeditor.js:配置文件

kindeditor-min.js:集成文件

由于使用的是ASP,所以将不需要的文件夹删掉。其中在asp中demo.aspx是参考代码,也可以删掉。

 3.配置KindEditor

(1)新建网站,将精简后的kindeditor文件夹放到网站根目录下下,并且引用kindeditor/asp/bin/LitJSON.dll文件。

(2)新建index.aspx文件,引入相关文件

<link href="kindeditor/plugins/code/prettify.css" rel="stylesheet" type="text/css" /> <script src="kindeditor/lang/zh_CN.js" type="text/javascript"></script> <script src="kindeditor/kindeditor.js" type="text/javascript"></script> <script src="kindeditor/plugins/code/prettify.js" type="text/javascript"></script> <script type="text/javascript"> KindEditor.ready(function (K) { var editor = K.create('#content', { //上传管理 uploadJson: 'kindeditor/asp/upload_json.ashx', //文件管理 fileManagerJson: 'kindeditor/asp/file_manager_json.ashx', allowFileManager: true, //设置编辑器创建后执行的回调函数 afterCreate: function () { var self = this; K.ctrl(document, 13, function () { self.sync(); K('form[name=example]')[0].submit(); }); K.ctrl(self.edit.doc, 13, function () { self.sync(); K('form[name=example]')[0].submit(); }); }, //上传文件后执行的回调函数,获取上传图片的路径 afterUpload : function(url) { alert(url); }, //编辑器高度 width: '700px', //编辑器宽度 height: '450px;', //配置编辑器的工具栏 items: [ 'source', '|', 'undo', 'redo', '|', 'preview', 'print', 'template', 'code', 'cut', 'copy', 'paste', 'plainpaste', 'wordpaste', '|', 'justifyleft', 'justifycenter', 'justifyright', 'justifyfull', 'insertorderedlist', 'insertunorderedlist', 'indent', 'outdent', 'subscript', 'superscript', 'clearhtml', 'quickformat', 'selectall', '|', 'fullscreen', '/', 'formatblock', 'fontname', 'fontsize', '|', 'forecolor', 'hilitecolor', 'bold', 'italic', 'underline', 'strikethrough', 'lineheight', 'removeformat', '|', 'image', 'multiimage', 'flash', 'media', 'insertfile', 'table', 'hr', 'emoticons', 'baidumap', 'pagebreak', 'anchor', 'link', 'unlink', '|', 'about' ] }); prettyPrint(); }); </script>

(3)在页面中添加一个textbox控件,将id命名为content,把属性"TextMode"属性改为Multiline

<body> <form runat="server"> <div> <asp:TextBox name="content" TextMode="MultiLine" runat="server"></asp:TextBox> </div> </form> </body>

 (4)在浏览器查看

4.附件上传原理

在asp文件夹下有两个重要的file_manager_json.ashx,upload_json.ashx,一个负责文件管理,一个负责上传管理。你可以根据自己需求进行相关修改。

原理:通过实现接口IHttpHandler来接管HTTP请求。

file_manager_json.ashx

<%@ webhandler Language="C#" class="FileManager" %> /** * KindEditor ASP * 文件管理 */ using System; using System.Collections; using System.Web; using System.IO; using System.Text.RegularExpressions; using LitJson; using System.Collections.Generic; public class FileManager : IHttpHandler { public void ProcessRequest(HttpContext context) { String aspxUrl = context.Request.Path.Substring(0, context.Request.Path-l astIndexOf("/") + 1); //根目录路径,相对路径 String rootPath = "http://wwwblogs-com/attached/"; //根目录URL,可以指定绝对路径,比如 http://www.yoursite-com/attached/ String rootUrl = aspxUrl + "http://wwwblogs-com/attached/"; //图片扩展名 String fileTypes = "jpg,jpg,jpg,jpg,jpg"; String currentPath = ""; String currentUrl = ""; String currentDirPath = ""; String moveupDirPath = ""; String dirPath = context.Server.MapPath(rootPath); String dirName = context.Request.QueryString["dir"]; if (!String.IsNullOrEmpty(dirName)) { if (Array.IndexOf("image,flash,media,file".Split(','), dirName) == -1) { context.Response.Write("Invalid Directory name."); context.Response.End(); } dirPath += dirName + "/"; rootUrl += dirName + "/"; if (!Directory.Exists(dirPath)) { Directory.CreateDirectory(dirPath); } } //根据path参数,设置各路径和URL String path = context.Request.QueryString["path"]; path = String.IsNullOrEmpty(path) ? "" : path; if (path == "") { currentPath = dirPath; currentUrl = rootUrl; currentDirPath = ""; moveupDirPath = ""; } else { currentPath = dirPath + path; currentUrl = rootUrl + path; currentDirPath = path; moveupDirPath = Regex.Replace(currentDirPath, @"(.*?)[^\/]+\/$", "$1"); } //排序形式,name or size or type String order = context.Request.QueryString["order"]; order = String.IsNullOrEmpty(order) ? "" : order.ToLower(); //不允许使用..移动到上一级目录 if (Regex.IsMatch(path, @"\.\.")) { context.Response.Write("Access is not allowed."); context.Response.End(); } //最后一个字符不是/ if (path != "" && !path.EndsWith("/")) { context.Response.Write("Parameter is not valid."); context.Response.End(); } //目录不存在或不是目录 if (!Directory.Exists(currentPath)) { context.Response.Write("Directory does not exist."); context.Response.End(); } //遍历目录取得文件信息 string[] dirList = Directory.GetDirectories(currentPath); string[] fileList = Directory.GetFiles(currentPath); switch (order) { case "size": Array.Sort(dirList, new NameSorter()); Array.Sort(fileList, new SizeSorter()); break; case "type": Array.Sort(dirList, new NameSorter()); Array.Sort(fileList, new TypeSorter()); break; case "name": default: Array.Sort(dirList, new NameSorter()); Array.Sort(fileList, new NameSorter()); break; } Hashtable result = new Hashtable(); result["moveup_dir_path"] = moveupDirPath; result["current_dir_path"] = currentDirPath; result["current_url"] = currentUrl; result["total_count"] = dirList.Length + fileList.Length; List<Hashtable> dirFileList = new List<Hashtable>(); result["file_list"] = dirFileList; for (int i = 0; i < dirList.Length; i++) { DirectoryInfo dir = new DirectoryInfo(dirList[i]); Hashtable hash = new Hashtable(); hash["is_dir"] = true; hash["has_file"] = (dir.GetFileSystemInfos().Length > 0); hash["filesize"] = 0; hash["is_photo"] = false; hash["filetype"] = ""; hash["filename"] = dir.Name; hash["datetime"] = dir-l astWriteTime.ToString("yyyy-MM-dd HH:mm:ss"); dirFileList.Add(hash); } for (int i = 0; i < fileList.Length; i++) { FileInfo file = new FileInfo(fileList[i]); Hashtable hash = new Hashtable(); hash["is_dir"] = false; hash["has_file"] = false; hash["filesize"] = file.Length; hash["is_photo"] = (Array.IndexOf(fileTypes.Split(','), file.Extension.Substring(1).ToLower()) >= 0); hash["filetype"] = file.Extension.Substring(1); hash["filename"] = file.Name; hash["datetime"] = file-l astWriteTime.ToString("yyyy-MM-dd HH:mm:ss"); dirFileList.Add(hash); } context.Response.AddHeader("Content-Type", "application/json; charset=UTF-8"); context.Response.Write(JsonMapper.ToJson(result)); context.Response.End(); } public class NameSorter : IComparer { public int Compare(object x, object y) { if (x == null && y == null) { return 0; } if (x == null) { return -1; } if (y == null) { return 1; } FileInfo xInfo = new FileInfo(x.ToString()); FileInfo yInfo = new FileInfo(y.ToString()); return xInfo.FullName-compareTo(yInfo.FullName); } } public class SizeSorter : IComparer { public int Compare(object x, object y) { if (x == null && y == null) { return 0; } if (x == null) { return -1; } if (y == null) { return 1; } FileInfo xInfo = new FileInfo(x.ToString()); FileInfo yInfo = new FileInfo(y.ToString()); return xInfo.Length-compareTo(yInfo.Length); } } public class TypeSorter : IComparer { public int Compare(object x, object y) { if (x == null && y == null) { return 0; } if (x == null) { return -1; } if (y == null) { return 1; } FileInfo xInfo = new FileInfo(x.ToString()); FileInfo yInfo = new FileInfo(y.ToString()); return xInfo.Extension-compareTo(yInfo.Extension); } } public bool IsReusable { get { return true; } } }

upload_json.ashx

<%@ webhandler Language="C#" class="Upload" %> /** * KindEditor ASP * 上传管理 */ using System; using System.Collections; using System.Web; using System.IO; using System.Globalization; using LitJson; public class Upload : IHttpHandler { private HttpContext context; public void ProcessRequest(HttpContext context) { String aspxUrl = context.Request.Path.Substring(0, context.Request.Path-l astIndexOf("/") + 1); //文件保存目录路径 String savePath = "http://wwwblogs-com/attached/"; //文件保存目录URL String saveUrl = aspxUrl + "http://wwwblogs-com/attached/"; //定义允许上传的文件扩展名 Hashtable extTable = new Hashtable(); extTable.Add("image", "jpg,jpg,jpg,jpg,jpg"); extTable.Add("flash", "swf,flv"); extTable.Add("media", "swf,flv,mp3,wav,wma,wmv,mid,avi,mpg,asf,rm,rmvb"); extTable.Add("file", "doc,docx,xls,xlsx,ppt,htm,html,txt,zip,rar,gz,bz2"); //最大文件大小 int maxSize = 1000000; this.context = context; HttpPostedFile imgFile = context.Request.Files["imgFile"]; if (imgFile == null) { showError("请选择文件。"); } String dirPath = context.Server.MapPath(savePath); if (!Directory.Exists(dirPath)) { showError("上传目录不存在。"); } String dirName = context.Request.QueryString["dir"]; if (String.IsNullOrEmpty(dirName)) { dirName = "image"; } if (!extTable.ContainsKey(dirName)) { showError("目录名不正确。"); } String fileName = imgFile.FileName; String fileExt = Path.GetExtension(fileName).ToLower(); if (imgFile.InputStream == null || imgFile.InputStream.Length > maxSize) { showError("上传文件大小超过限制。"); } if (String.IsNullOrEmpty(fileExt) || Array.IndexOf(((String)extTable[dirName]).Split(','), fileExt.Substring(1).ToLower()) == -1) { showError("上传文件扩展名是不允许的扩展名。 只允许" + ((String)extTable[dirName]) + "格式。"); } //创建文件夹 dirPath += dirName + "/"; saveUrl += dirName + "/"; if (!Directory.Exists(dirPath)) { Directory.CreateDirectory(dirPath); } String ymd = DateTime.Now.ToString("yyyyMMdd", DateTimeFormatInfo.InvariantInfo); dirPath += ymd + "/"; saveUrl += ymd + "/"; if (!Directory.Exists(dirPath)) { Directory.CreateDirectory(dirPath); } String newFileName = DateTime.Now.ToString("yyyyMMddHHmmss_ffff", DateTimeFormatInfo.InvariantInfo) + fileExt; String filePath = dirPath + newFileName; imgFile.SaveAs(filePath); String fileUrl = saveUrl + newFileName; Hashtable hash = new Hashtable(); hash["error"] = 0; hash["url"] = fileUrl; context.Response.AddHeader("Content-Type", "text/html; charset=UTF-8"); context.Response.Write(JsonMapper.ToJson(hash)); context.Response.End(); } private void showError(string message) { Hashtable hash = new Hashtable(); hash["error"] = 1; hash["message"] = message; context.Response.AddHeader("Content-Type", "text/html; charset=UTF-8"); context.Response.Write(JsonMapper.ToJson(hash)); context.Response.End(); } public bool IsReusable { get { return true; } } }

5.优化改进

使用KindEditor文本编辑器时,发现不能在图片空间中修改已上传图片的信息,删除图片等,也不能进行目录操作,我觉得这是比CKEditor和CKFinder结合的文本编辑器弱势的地方。

大致想了下,有两个方法可以解决:

方法一、独立写一个图片管理的模块,进行可视化操作

方法二、修改plugins/filemanager/filemanager.js,并结合handler进行操作。(这个方法扩展性比较好)

如果有人已经解决了这个问题,希望可以分享一下。
