本文實(shí)例講述了asp.net中MVC借助Iframe實(shí)現(xiàn)無(wú)刷新上傳文件的方法。。具體實(shí)現(xiàn)方法如下：

html:
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(shù)：
代碼如下:var UploadFun = {
    CallBack: function (msg) {
        $.messager.alert('上傳文件', msg, 'info');

    }
};
后臺(tái)處理：
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(guò)程中發(fā)生錯(cuò)誤，請(qǐng)重試";
    }
    Response.Write("<script type=/"text/javascript/"> parent.UploadFun.CallBack(/"" + error + "/")</script>");
}

希望本文所述對(duì)大家的asp.net程序設(shè)計(jì)有所幫助。
