• ASP.NET MVC- KindEditor的使用


      我用过几个EDITOR,还是比较喜欢KINDEDITOR。这个工作可能最近要用到了,周末在家花时间了解了一下。做了一下备注在这里,以备日后方便查阅。

      1.首先去KINDEDITOR的官网下载最新的版本,然后在MVC的CONTENT文件夹下面把下载的包解压放进去。

      2.然后看一下VIEW视图做一下引用,显示

    @{
        Layout = null;
    }
    
    <!DOCTYPE html>
    
    <html>
    <head>
        <meta name="viewport" content="width=device-width" />
        <title>Index</title>
        <link rel="stylesheet" href="/Content/KindEditor/themes/default/default.css" />
        <script charset="utf-8" src="/Content/KindEditor/kindeditor-min.js"></script>
        <script charset="utf-8" src="/Content/KindEditor/lang/zh_CN.js"></script>
        <script>
            var editor;
            KindEditor.ready(function (K) {
                editor = K.create('textarea[name="txtContent"]', {
                    resizeType: 1,
                    uploadJson: '@Url.Action("UploadImages", "Default")'
                });
            });
        </script>
    </head>
    <body>
        <div>
            <form id="formGuestBook" method="post" action="/Default/Add">
                <!--类名/方法名-->
                姓名:<input type="text" id="txtName" name="txtName" /><br />
                内容:
                <textarea id="txtContent" name="txtContent" style="800px;height:400px;visibility:hidden;"></textarea>
    
                <input type="submit" name="btnSubmitGuestBook" value="提交留言" />
            </form>
        </div>
    </body>
    </html>

      3.这里提交后给Controller后报错,错误如下:

      解决很简单,在Controller的方法前加一下[ValidateInput(false)],如下代码所示:

         [ValidateInput(false)]
            public ActionResult Add(string txtName, string txtContent)
            {
                return View();
            }

      4.最后改自官网自带的图片上传功能,原来是WEBFORM的HANDLER写的。改成MVC的。使用前需引用LITJSON

          public ActionResult UploadImages()
            {
    
                //String aspxUrl = HttpContext.Request.Path.Substring(0, HttpContext.Request.Path.LastIndexOf("/") + 1);
                String aspxUrl = "";
    
                //文件保存目录路径
                String savePath = "/Content/KindEditor/attached/";
    
                //文件保存目录URL
                String saveUrl = aspxUrl + "/Content/KindEditor/attached/";
    
                //定义允许上传的文件扩展名
                Hashtable extTable = new Hashtable();
                extTable.Add("image", "gif,jpg,jpeg,png,bmp");
                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 = HttpContext;
    
                HttpPostedFileBase imgFile = HttpContext.Request.Files["imgFile"];
                if (imgFile == null)
                {
                    showError("请选择文件。");
                }
    
                String dirPath = HttpContext.Server.MapPath(savePath);
                if (!Directory.Exists(dirPath))
                {
                    showError("上传目录不存在。");
                }
    
                String dirName = HttpContext.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;
                return Content(JsonMapper.ToJson(hash));
    
                //return View();
            }
    
            private ContentResult showError(string message)
            {
                Hashtable hash = new Hashtable();
                hash["error"] = 1;
                hash["message"] = message;
    
    
                return Content(JsonMapper.ToJson(hash));
            }
