[ASP.net教程]MVC KindEdit


先将下载的KindEditor放到项目中

View页面

<!DOCTYPE html>
<html>
<head>
    <meta name="viewport" content="width=device-width" />
    <title>Index</title>
    @Scripts.Render("~/bundles/kindeditor")    //MVC4 方法,加载 kindeditor/kindeditor.js
    <script type="text/javascript">
        var editor;
        KindEditor.ready(function (K) {
            editor = K.create('textarea[name="Information"]', {
                allowFileManager: true,                                            //是否可以浏览上传文件
                allowUpload: true,                                                     //是否可以上传
                fileManagerJson: '/KindEditor/ProcessRequest',      //浏览文件方法
                uploadJson: '/KindEditor/UploadImage'                    //上传文件方法  //注意这两个路径
            });
        });
    </script>
</head>
<body>
    @using (Html.BeginForm())
    {
        @Html.TextArea("Information", new { style = "width:800px;height:400px" })
        <input type="submit" value="Submit" />
        <hr />
        @Html.Raw(ViewData["kindeditor"])
    }

    <%--<% Html.BeginForm(); %>这是MVC3的写法 上面是MVC4的
        <textarea name="Information" ></textarea>
        <input type="submit" value="Submit" />
        <hr />
        <%: ViewData["kindeditor"] %>
    <% Html.EndForm(); %>--%>
</body>
</html>

 

Controller:
[ValidateInput(false)]        //不加提交会报错
public ActionResult Index(string Information)
{
    ViewData["kindeditor"] = Information;
    return View();
}

 

上传方法:
[HttpPost]
public ActionResult UploadImage()
{
    string savePath = "/UploadImages/";
    string saveUrl = "/UploadImages/";
    string fileTypes = "gif,jpg,jpeg,png,bmp";
    int maxSize = 1000000;

    Hashtable hash = new Hashtable();

    HttpPostedFileBase file = Request.Files["imgFile"];
    if (file == null)
    {
        hash = new Hashtable();
        hash["error"] = 1;
        hash["message"] = "请选择文件";
        return Json(hash, "text/html;charset=UTF-8"); 
    }

    string dirPath = Server.MapPath(savePath);
    if (!Directory.Exists(dirPath))
    {
        hash = new Hashtable();
        hash["error"] = 1;
        hash["message"] = "上传目录不存在";
        return Json(hash, "text/html;charset=UTF-8"); 
    }

    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"] = 1;
        hash["message"] = "上传文件大小超过限制";
        return Json(hash, "text/html;charset=UTF-8"); 
    }

    if (string.IsNullOrEmpty(fileExt) || Array.IndexOf(fileTypes.Split(','), fileExt.Substring(1).ToLower()) == -1)
    {
        hash = new Hashtable();
        hash["error"] = 1;
        hash["message"] = "上传文件扩展名是不允许的扩展名";
        return Json(hash, "text/html;charset=UTF-8"); 
    }

    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"] = 0;
    hash["url"] = fileUrl;

    return Json(hash, "text/html;charset=UTF-8");
}

浏览方法:
public ActionResult ProcessRequest()
{
    //String aspxUrl = context.Request.Path.Substring(0, context.Request.Path.LastIndexOf("/") + 1);

    //根目录路径,相对路径
    String rootPath = "/UploadImages/";
    //根目录URL,可以指定绝对路径,
    String rootUrl = "/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);

    }

    }

    //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.End();

    if (!Directory.Exists(currentPath))
    {

        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":

    result["total_count"] = dirList.Length + fileList.Length;
    List<Hashtable> dirFileList = new List<Hashtable>();

P.S 最近发现 Json(hash); 有时可能有问题,都改用Json(hash, "text/html;charset=UTF-8");
