本文實(shí)例講述了asp.net中MVC借助Iframe實(shí)現(xiàn)無刷新上傳文件的方法。分享給大家供大家參考。具體實(shí)現(xiàn)方法如下：
    html:
    復(fù)制代碼 代碼如下:<div id="uploadwindow">
    <form action="/ShopActivitys/ImportActivityItems" id="form1" name="form1" enctype="multipart/form-data" method="post" target="hidden_frame">
    <table>
    <tr>
    <td>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(shù)：
    復(fù)制代碼 代碼如下:var UploadFun = {
    CallBack: function (msg) {
    $.messager.alert('上傳文件', msg, 'info');
    }
    };
    后臺(tái)處理：
    復(fù)制代碼 代碼如下:public void ImportActivityItems()
    {
    string error = "導(dǎo)入成功";
    try
    {
    var f = Request.Files["activityitemsfile"];
    var fpath = Server.MapPath("/Upload/活動(dòng)鏈接數(shù)據(jù)/");
    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(dǎo)入過程中發(fā)生錯(cuò)誤，請(qǐng)重試";
    }
    Response.Write("<script type=\"text/javascript\"> parent.UploadFun.CallBack(\"" + error + "\")</script>");
    }
