asp.net mvc to achieve the use of IFRAME without refreshing upload file instance _ practical skills

The example of this article is about the method that MVC realizes without refreshing upload file in asp.net. Share to everyone for your reference. The implementation methods are as follows:

Html:

Copy Code code as follows:

<div id= "Uploadwindow" style= "Display:none;" >
<form action= "/shopactivitys/importactivityitems" id= "Form1" Name= "Form1" Enctype= "Multipart/form-data" Post "target=" Hidden_frame >
<table style= "width:300px;" >
<tr>
&LT;TD style= "width:80px; Display:block; " > select File:</td>
<td>
<input type= "File" id= "file" name= "Activityitemsfile"/>
</td>
</tr>
</table>
<input type= "Submit" value= "Upload file"/>
<iframe name= ' hidden_frame ' id= ' hidden_frame ' style= ' Display:none ' ></iframe>
</form>
</div>

callback function:

Copy Code code as follows:

var uploadfun = {
Callback:function (msg) {
$.messager.alert (' Uploading Files ', msg, ' info ');

}
};

Background processing:

Copy Code code as follows:

public void Importactivityitems ()
{
String error = "Import succeeded";
Try
{
var f = request.files["Activityitemsfile"];

var Fpath = Server.MapPath ("/upload/Active link Data/");
if (! Directory.Exists (Fpath))
Directory.CreateDirectory (Fpath);
String fullfilename = Fpath + DateTime.Now.ToFileTime () + f.filename;
F.saveas (Fullfilename);
}
catch (Exception ex)
{
Logger.error (ex. ToString ());
Error = "Errors occurred during import, please try again";
}
Response.Write ("<script type=\" text/javascript\) > parent. Uploadfun.callback (\ "" + Error + "\") </script> ");
}
