Uploadify是JQuery的一個上傳外掛程式，實現的效果非常不錯，帶進度顯示。Uploadify官方網址：http://www.uploadify.com/，在MVC中使用的方法可以參考 jQuery Uploadify在ASP.NET MVC3中的使用和 Asp.net Mvc中使用uploadify實現圖片縮放儲存。本文是一個簡單的介紹Demo，主要是動態傳遞參數方法：通過formdata 向處理常式傳遞額外的表單資料：代碼如下:<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="http://www.w3.org/1999/xhtml"><head runat="server"> <title></title> <link href="uploadify/uploadify.css" type="text/css" rel="Stylesheet" /> <script type="text/javascript" src="uploadify/jquery-1.7.2.min.js"></script> <script type="text/javascript" src="uploadify/swfobject.js"></script> <script type="text/javascript" src="uploadify/jquery.uploadify.min.js"></script> <script type="text/javascript"> $(function () { var taskId = "<%= TaskID %>"; var activityId = "<%= ActivityId %>"; var userId = "<%= GetCurrentLoginUser().ID %>"; $("#<%=FileUpload1.ClientID %>").uploadify( { 'swf': 'uploadify/uploadify.swf', 'uploader': 'UploadHandler.aspx', 'auto': false, 'method': 'post', 'multi': true, 'buttonText': '瀏覽', 'buttonImg': 'uploadify/browse.jpg', 'folder': '../uploadfile', 'fileDesc': '附件', 'onUploadStart': function (event, data) { //this is where you will send the form //data, but remember to get if from post in the .ashx file, by contex.Request["gallaryId"] $("#<%=FileUpload1.ClientID %>").uploadify('settings', 'formData', { 'taskId': taskId, 'activityId': activityId, 'userId': userId, 'secInfo': $("#<%=ddlsecInfo.ClientID %>").val()} //note hiddenGallaryId would //have the gallaryId which im sending through post , make sure it is rendered in your page( //i.e.not concealed by a multiview control e.t.c) ); } }); }); </script></head><body> <form id="form1" runat="server"> <asp:FileUpload ID="FileUpload1" runat="server" /> <asp:DropDownList ID="ddlsecInfo" runat="server"> <asp:ListItem Text="公開" Value="1"> </asp:ListItem> <asp:ListItem Text="普通" Value="2"> </asp:ListItem> <asp:ListItem Text="機密" Value="3"> </asp:ListItem> </asp:DropDownList> <a href="javascript: $('#<%=FileUpload1.ClientID %>').uploadify('upload','*')">上傳</a> <a href="javascript:$('#<%=FileUpload1.ClientID %>').uploadify('cancel','*')">取消上傳</a> </form></body></html>
