张:一个完整的上传

下载LOFTER 我的照片书 |

效果:此上传除了弹出文件选择对话框外,不再弹出其它,而且会将图片地址自动填入输入框,并且自动还原上传表单.非常漂亮,是本人调试正确的.
添加的页面:用iframe调入文件选择的输入框
<form name=myform method=post action='admin_admanage.asp'>
<tr id=flagsetting6<%If isEdit Then If Rs("flag")=5 Then Response.Write " style=""display:none"""%>>
<td class=TableRow1 align=right><strong>上传文件:</strong></td>
<td class=TableRow1> <iframe name="image" frameborder=0 width=100% height=25 scrolling=no src="../UpLoadFiles/upfilehtm.asp?formname=myform&editname=ImageUrl"></iframe>
</td>
</tr>
</form>

以下文件统一放在UploadFiles文件夹下,文件清单:upfile.asp+upfilehtm.asp+upload.inc+pic文件夹
