记上面的js，整合出可以用的用户控件（asp.net方面）

代码如下：

<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="UploadFile.ascx.cs" Inherits="DTJG.Web.UControl.UploadFile" %>
<div class="UploadTool"><ul class="UploadTool_ul"><li><input onchange="ajaxFileUpload(this);" style="width:50px" runat="server" type="file" onpropertychange="this.value" id="Upload_File" /></li></ul></div>
<div class="UploadList"><ul class='ullink' id="FileList_Ul" style="display:none" runat="server"></ul><asp:HiddenField ID="JosnHF" runat="server" /><asp:HiddenField ID="MaxSizeHF" runat="server" /><asp:HiddenField ID="FileFilterHF" runat="server" /></div>
<script type="text/javascript" src="../Js/UploadFile.js"></script>
<script type="text/javascript" src="../Js/ajaxfileupload.js"></script>
<script type="text/javascript">
function ajaxFileUpload(node){
var uploadId=<%=FileList_Ul.ClientID %>;
uploadId.OnUpload(node);
}
</script>

要引用的 两个js文件”ajaxfileupload.js“和jquery-1.3.2.min.js

第三个”UploadFile.js“就是前面的javascript.
