发现还没有aspupload这个组件的,这两样功能的解决方案,现把我的改进方案写在这里!谢谢
关于aspupload上传组件,文件重命名,进度条的问题解决方案!
共用到4个文件,分别是1.asp,2.asp,bar.asp,framebar.asp
运行第一个文件:1.asp,执行上传操作!
<%
'''进度条
dim SPid,PID,barref
Set UploadProgress = Server.CreateObject("Persits.UploadProgress")
SPid = UploadProgress.CreateProgressID()
PID = "PID=" & SPid
barref = "framebar.asp?to=10&" & PID
%>
<SCRIPT language="javascript">
<!--
function ShowProgress()
//加载进度条
{
strAppVersion = navigator.appVersion;
if (document.upfile.filename.value != "")
{
if (strAppVersion.indexOf('MSIE') != -1 && strAppVersion.substr(strAppVersion.indexOf('MSIE')+5,1) > 4)
{
winstyle = "dialogWidth=375px; dialogHeight:175px; center:yes;status:no";
window.showModelessDialog('<% = barref %>&b=IE',window,winstyle);

function isPic(){
var temp;
var ExtList = ".jpg.gif.bmp.png.swf";//客户端，检测文件后缀名，省得上传完成后，才报文件类型错误！
var filename = upfile.filename.value;
var the_ext = filename.substr(filename.lastIndexOf(".")+1).toLowerCase();

alert("不是图片，请选择图片文件！");
