aspupload文件重命名及上传进度条的解决方法附代码第1/2页


答案：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); 
    } 
    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; 
}

上一个：asp动态include文件，方便多模板的实现
下一个：asp实现限制搜索的关键字的函数
