为什么不IFRAME更新整个窗体asp.net的MVC [英] why iframe not updating the entire form asp.net mvc

问题描述

有关文件上传，我用的iframe，我的JavaScript像这样

for fileupload i used iframe,I have javascript like this

 function uploadFileUsingAnIframe(iFrame_id, form_id) {
            var iframe = document.createElement("iframe");
            iframe.setAttribute("id", iFrame_id);
            iframe.setAttribute("name", iFrame_id);
            iframe.setAttribute("width", "0");
            iframe.setAttribute("height", "0");
            iframe.setAttribute("border", "0");
            iframe.setAttribute("style", "width: 0px; height:0px; border: none;");

            document.body.appendChild(iframe);
            document.getElementById(form_id).target = iFrame_id;

        }

和在视图/ ASPX为

and in the view/aspx as

<% using (Html.BeginForm("AddFile", "uploadfile", FormMethod.Post, new
   {
       id = "uploadform",
       enctype = "multipart/form-data",
       target = "uploadFileFrame",
       onsubmit = "javascript:uploadFileUsingAnIframe('uploadFileFrame','uploadform');"
   })) 

％>

{ %>
<input type="file" id="addedFile" name="addedFile" /><br />
    <input type="submit" id="addfile" value="Addfile" />
          <div id="upload">
       //here i show the uploaded filenames from model </div>

<%} %>

问题是div没有显示最新手段的观点并没有更新模型值，可能是目标或参数传递给JavaScript函数需要改变以获得所需的视图。你们可以帮我了。

problem is the div is not showing latest means the view is not updating the model values ,may be the target or the parameters to be passed to the javascript function need to be changed to get required view. guys could you help me out.

推荐答案

您可以使用Valums上传。这是非常好的上传的js库，可以很容易地定制，而且已经有iframe的文件上传功能。

You can use Valums Uploader. It's very good upload js library that can be easily customized and already have iframe file upload functionality.
