ASP.NET MVC框架中引入JQUERY JQRTE控件
经过将近两周的努力,终于将JQUERY的JQRTE文本编辑器控件引入到了asp.net mvc框架中,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
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:
[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。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:
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:
