本文實例講述了asp.net中MVC借助Iframe實現無刷新上傳文件的方法。分享給大家供大家參考。具體實現方法如下：

html:

復制代碼 代碼如下:<div id="uploadwindow" style="display: none;">

<form action="/ShopActivitys/ImportActivityItems" id="form1" name="form1" enctype="multipart/form-data" method="post" target="hidden_frame">

<table style="width: 300px;">

<tr>

<td style="width: 80px; display: block;">選擇文件：</td>

<td>

<input type="file" id="file" name="activityitemsfile" />

</td>

</tr>

</table>

<input type="submit" value="上傳文件" />

<iframe name='hidden_frame' id="hidden_frame" style='display: none'></iframe>

</form>

</div>

CallBack函數：

復制代碼 代碼如下:var UploadFun = {

CallBack: function (msg) {

$.messager.alert('上傳文件', msg, 'info');

}

};

后臺處理：

復制代碼 代碼如下:public void ImportActivityItems()

{

string error = "導入成功";

try

{

var f = Request.Files["activityitemsfile"];

var fpath = Server.MapPath("/Upload/活動鏈接數據/");

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 = "導入過程中發生錯誤，請重試";

}

Response.Write("<script type=\"text/javascript\"> parent.UploadFun.CallBack(\"" + error + "\")</script>");

}
