高分求救上传图片后文件路径获取不到，问题解决，马上给分，谢!
问题是这样的：
我在表单中有这样一个图片上传控件：
<form action= "save.asp?abc=add_yes&id= <%= request( "id ") %> " method= "post " name= "form " id= "form " onsubmit= "javascript:return checksignup1(); ">
<tr>
<td align= "right " class= "font-14 "> 图片上传： </td>
<td> <script language = "JavaScript ">
function loadForm()
{
UploadFile_b.txtfile_b.value = document.form.photo.value;
UploadFile_b.txtfile_b.value = document.form.hiddenphoto.value;
document.form.hiddenphoto.value = UploadFile_b.txtfile_b.value;
return true
}
</script>
<input type= "hidden " name= "hiddenphoto " value= " " onChange= "loadForm() ">
<textarea name= "photo " style= "display:none " onChange= "loadForm "> </textarea>
<iframe style= "top:2px " ID= "UploadFile_b " src= "upload_b.asp " frameborder=0 scrolling=no width= "350 " height= "25 "> </iframe>
</td>
</tr>
<input name= "Submit " type= "submit " class= "font-a14 " value= "提交修改 ">
</form>
upload_b.asp文件如下:(可以原封不动复制)
<!--#include file= "../../mycartconn/conn.asp "-->
<SCRIPT language=javascript>
function check_file()
{
var strFileName=upform.txtfile_b.value;
if (strFileName== " ")

return false;
}
}

实在太长了，如果只是上传张图片，要得到图片名的话：
<link href=sitecss.css rel=stylesheet>

[解决办法]
你没有给hiddenphoto赋值,怎么能得到它的值呢,至少我是没有看到,呵呵.
在你的upfile_b.asp中的局部代码修改如下:
if founderr <> true then
randomize
ranNum=int(900*rnd)+100
filename=SavePath&year(now)&month(now)&day(now)&hour(now)&minute(now)&second(now)&ranNum& ". "&fileExt
file.SaveToFile Server.mappath(FileName) '保存文件
msg= "上传文件成功！ "
response.write " <script> window.opener.document.form.hiddenphoto.value= ' "&FileName& " ' </script> "
%>
<body leftmargin= "0 " topmargin= "0 " style= "font-size:12px;color:0055b0 " bgcolor= "f5f5f5 ">
<FORM method= "post " action= " " name= "upform ">
<p style= "margin-top:5 "> 上传成功！ <input name= "txtfile_b " type= "text " class= "input-16 " size= "10 " value= " <%=FileName%> "> > > <a href= " <%=FileName%> " target= "_blank "> <font color= "0055b0 "> <u> 浏览图片 </u> </font> </a>
</form>
<%
end if
加了一行,给父级隐藏域赋值.
