asp上传文件的同时显示进度条

来源: 作者: 时间:2008-07-27 Tag:进度条   文件   上传   asp   点击:

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!

 

1.asp
 <%
'''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);
    }
    else
    {
      window.open('<% = barref %>&b=NN','','width=370,height=165', true);
    }
  }
  return true;
}
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();
    if (ExtList.indexOf(the_ext)==-1){
        alert("不是图片, 请选择图片文件!");
        return false;
    }
    return true;
}
//-->
</SCRIPT>
  <html>
  <head></head>
  <body>
  <form method="post"enctype="multipart/form-data"action="2.asp?<% = PID %>"name="upfile"OnSubmit="return ShowProgress();">
  
  选择要上传的文件:<br>
  <input type=file name="filename"><br>
  <input type=submit value="上传" onclick="return isPic()">
  </form>
       
  </body>
  </html>

2.asp
  <%

Set Upload = Server.CreateObject("Persits.Upload")

' Prevent overwriting
Upload.OverwriteFiles = False

' We use memory uploads, 文件大小限制 ,单位:b
Upload.SetMaxSize 1*1024*1024*1024, true

if Request.QueryString("PID") = "" then
                Upload.ProgressID="010D60EB00C5AA4B"
        else
                Upload.ProgressID=Request.QueryString("PID")
        end if

On Error Resume Next

' Save to memory 保存到内存
Upload.Save

If Err.Number = 8 Then
   Response.Write "文件大于1G"
End If


'为使文件不重名, 用系统时间+随机数, 作为文件名
Dim ranNum
        randomize
        ranNum=int(999*rnd)
        CreateName=year(now)&month(now)&day(now)&hour(now)&minute(now)&second(now)&ranNum
NewName = CreateName
'保存文件路径
articlepath = Server.MapPath("upload1")


For Each File in Upload.Files
        FileExt=Lcase(replace(File.ext,".",""))
                '服务器端判断文件类型,动网论坛的判断方式
                If CheckFileExt(FileExt)=false then
                        Response.write "文件格式不正确,或不能为空 [ <a href=# onclick=history.go(-1)>重新上传</a> ]"
                       
                        else
   File.SaveAs articlepath & "/" & NewName & File.ext
   Response.Write "New name: " & File.FileName & "<BR>"
End If

Next

%>
<%
'服务器端判断文件类型,动网论坛的判断方式
Private Function CheckFileExt(FileExt)

        If FileExt="" or IsEmpty(FileExt) Then
                CheckFileExt=false
                Exit Function
        End If
        If Lcase(FileExt)="asp" or Lcase(FileExt)="asa" or Lcase(FileExt)="aspx" then
                CheckFileExt=false
                Exit Function
        End If
        If Lcase(FileExt)="gif" or Lcase(FileExt)="jpg" or Lcase(FileExt)="png" or Lcase(FileExt)="swf" or Lcase(FileExt)="bmp" then
                CheckFileExt=true
                Exit Function
        Else
                CheckFileExt=false
        End If
End Function
