ASP.NET MVC引入JQUERY JQRTE控件

主要步骤如下：
1,在asp.net mvc项目中引入jqrte类库，声明辅助类用于存储服务器端上载文件的信息

复制代码代码如下:

public class ViewDataUploadFilesResult 
{ 
public string message { get; set; } 
//public int Length { get; set; } 
public string imagepath { get; set; } 
public string error { get; set; } 
}

2，编写处理文件上载服务器段代码，并将上载的文件信息返回给客户端，代码如下：

复制代码代码如下:

[AcceptVerbs(HttpVerbs.Post)] 
public JsonResult UploadFiles(FormCollection collection) 
{ 
var r = new ViewDataUploadFilesResult(); 
foreach (string file in Request.Files) 
{ 
string url = Request.Url.Authority; 
url = "http://" + url; 
HttpPostedFileBase hpf = Request.Files[file] as HttpPostedFileBase; 
string date = DateTime.Now.Date.ToShortDateString(); 
string path = Path.Combine( 
AppDomain.CurrentDomain.BaseDirectory, 
"Content"); 
string datePath = Path.Combine(path,date); 
Directory.CreateDirectory(datePath); 
url += "/Content/"; 
url += date; 
url += "/"; 
url += Path.GetFileName(hpf.FileName); 
if (hpf.ContentLength == 0) 
continue; 
string savedFileName = Path.Combine( 
datePath, 
Path.GetFileName(hpf.FileName)); 
try 
{ 
hpf.SaveAs(savedFileName); 
} 
catch (Exception e) 
{ 
r.error = e.ToString(); 
} 
//r.Name = savedFileName; 
//r.Length = hpf.ContentLength; 
r.imagepath = url; 
r.message = "ok"; 
r.error = "ok"; 
//r.Add(new ViewDataUploadFilesResult() 
//{ 
// Name = savedFileName, 
// Length = hpf.ContentLength 
//}); 
} 
JsonResult jsonResult = Json(r); 
jsonResult.ContentType = "text/html"; 
return jsonResult; 
}

之所以搞了这么长时间，问题也主要出在这儿，开始用的是return json(r),发现jquery的回调函数总是无法获得服务器端的json，反而会跳出个下载文件对话框，反复阅读jquery的源代码，折磨了一周多后，在asp.net mvc官方论坛上注册了个用户，经过一番讨论，最后发现对于有file控件的ajax form，在action方法中应当制定json的contentType才会正确处理json对象，源代码如上，感谢热心朋友的帮助，要不然不知道这个问题会折磨到我什么时候（已经好几天睡不好觉了：()。原贴链接如下：http://forums.asp.net/t/1439867.aspx

3.修改jqrte的fileupload源代码，只要改一下action路径就行，在jquery.jqrte.min.js中修改uploads函数：增加和修改的代码如下：

复制代码代码如下:

var path = window.location.href.replace(/editor/, "UploadFiles"); 
// alert(path); 
$.jQRTE.ajaxFileUpload({ url: path, secureuri: false, fileElementId: "upload" + uid + "_fileToUpload", dataType: "json",

4，准备编辑器页面，原代码如下：

复制代码代码如下:

<asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server">
