最近做项目要用文本编辑器，编辑器好多种，这里介绍KindEditor在asp.net mvc4中的使用方法。
一、准备工作：
1.下载KindEditor.去官网：http://www.kindsoft.net/
2.解压，拷贝到项目中（这里面有些例子，可以先删除掉在拷贝到项目中。）
二、使用步骤：
1.view页面
<script>
var editor;
KindEditor.ready(function (K) {
editor = K.create('textarea[id="content"]', {//textarea
allowFileManager: true, //是否允许文件上传
allowUpload: true,
fileManagerJson: '/KindEditor/ProcessRequest', //浏览文件方法
uploadJson: '/KindEditor/UploadImage' //上传文件方法
});
});
</script> TextArea:
<div class="editor-field">
@Html.TextAreaFor(model => model.Content, new { id="content",style = "width:750px;height:400px" })
@Html.ValidationMessageFor(model => model.Content)
</div>
2.Controller中定义方法，就是js中 fileManagerJson和uploadJson的执行方法
public class KindEditorController : Controller
{
//上传方法
[HttpPost]
public ActionResult UploadImage()
{
string savePath = "/Content/UploadImages/";
string saveUrl = "/Content/UploadImages/";
string fileTypes = "gif,jpg,jpeg,png,bmp";
int maxSize = ; Hashtable hash = new Hashtable(); HttpPostedFileBase file = Request.Files["imgFile"];
if (file == null)
{
hash = new Hashtable();
hash["error"] = ;
hash["message"] = "请选择文件";
return Json(hash);
} string dirPath = Server.MapPath(savePath);
if (!Directory.Exists(dirPath))
{
hash = new Hashtable();
hash["error"] = ;
hash["message"] = "上传目录不存在";
return Json(hash);
} string fileName = file.FileName;
string fileExt = Path.GetExtension(fileName).ToLower(); ArrayList fileTypeList = ArrayList.Adapter(fileTypes.Split(',')); if (file.InputStream == null || file.InputStream.Length > maxSize)
{
hash = new Hashtable();
hash["error"] = ;
hash["message"] = "上传文件大小超过限制";
return Json(hash);
} if (string.IsNullOrEmpty(fileExt) || Array.IndexOf(fileTypes.Split(','), fileExt.Substring().ToLower()) == -)
{
hash = new Hashtable();
hash["error"] = ;
hash["message"] = "上传文件扩展名是不允许的扩展名";
return Json(hash);
} string newFileName = DateTime.Now.ToString("yyyyMMddHHmmss_ffff", DateTimeFormatInfo.InvariantInfo) + fileExt;
string filePath = dirPath + newFileName;
file.SaveAs(filePath);
string fileUrl = saveUrl + newFileName; hash = new Hashtable();
hash["error"] = ;
hash["url"] = fileUrl; return Json(hash, "text/html;charset=UTF-8"); ; } //浏览方法
public ActionResult ProcessRequest()
{
//根目录路径，相对路径
String rootPath = "/Content/UploadImages/";
//根目录URL，可以指定绝对路径，
String rootUrl = "/Content/UploadImages/";
//图片扩展名
String fileTypes = "gif,jpg,jpeg,png,bmp"; String currentPath = "";
String currentUrl = "";
String currentDirPath = "";
String moveupDirPath = ""; //根据path参数，设置各路径和URL
String path = Request.QueryString["path"];
path = String.IsNullOrEmpty(path) ? "" : path;
if (path == "")
{
currentPath = Server.MapPath(rootPath);
currentUrl = rootUrl;
currentDirPath = "";
moveupDirPath = "";
}
else
{
currentPath = Server.MapPath(rootPath) + path;
currentUrl = rootUrl + path;
currentDirPath = path;
moveupDirPath = Regex.Replace(currentDirPath, @"(.*?)[^\/]+\/$", "$1");
} //排序形式，name or size or type
String order = 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, @"\.\."))
{
Response.Write("Access is not allowed.");
Response.End();
}
//最后一个字符不是/
if (path != "" && !path.EndsWith("/"))
{
Response.Write("Parameter is not valid.");
Response.End();
}
//目录不存在或不是目录
if (!Directory.Exists(currentPath))
{
Response.Write("Directory does not exist.");
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 = ; i < dirList.Length; i++)
{
DirectoryInfo dir = new DirectoryInfo(dirList[i]);
Hashtable hash = new Hashtable();
hash["is_dir"] = true;
hash["has_file"] = (dir.GetFileSystemInfos().Length > );
hash["filesize"] = ;
hash["is_photo"] = false;
hash["filetype"] = "";
hash["filename"] = dir.Name;
hash["datetime"] = dir.LastWriteTime.ToString("yyyy-MM-dd HH:mm:ss");
dirFileList.Add(hash);
}
for (int i = ; 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().ToLower()) >= );
hash["filetype"] = file.Extension.Substring();
hash["filename"] = file.Name;
hash["datetime"] = file.LastWriteTime.ToString("yyyy-MM-dd HH:mm:ss");
dirFileList.Add(hash);
}
//Response.AddHeader("Content-Type", "application/json; charset=UTF-8");
//context.Response.Write(JsonMapper.ToJson(result));
//context.Response.End();
return Json(result, "text/html;charset=UTF-8", JsonRequestBehavior.AllowGet);
} public class NameSorter : IComparer
{
public int Compare(object x, object y)
{
if (x == null && y == null)
{
return ;
}
if (x == null)
{
return -;
}
if (y == null)
{
return ;
}
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 ;
}
if (x == null)
{
return -;
}
if (y == null)
{
return ;
}
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 ;
}
if (x == null)
{
return -;
}
if (y == null)
{
return ;
}
FileInfo xInfo = new FileInfo(x.ToString());
FileInfo yInfo = new FileInfo(y.ToString()); return xInfo.Extension.CompareTo(yInfo.Extension);
}
} }
3.最后在处理提交的Action上加 [ValidateInput(false)]特性，不然提交的报错：从客户端(“”)中检测到有潜在危险的 Request.Form 值
