使aspx页面能接受html，asp的页面传送的文件
aspx接受aspx页面的文件很简单，用htmlinputfile,就可以了，但是如果接受html页面post的文件 function sendfile() function onuploadcompleted( errornumber, fileurl, filename, custommsg ) </script> string[] allowedext = new string[] { }, denyedext = new string[] { };
就不怎么好办了，我仿照asp的方法做法如下，自己测试通过，拿出来给大家共享，可以限制
文件内容，类型，大小，自定义存储位置，在congfig.xml内
html页的内容：（来自fckeditor）

if ( suploaderurl.length == 0 )
suploaderurl = txtcustomurl.value ;
if ( suploaderurl.length == 0 )

return ;
}
eurl.innerhtml = suploaderurl ;
txturl.value = '' ;
frmupload.action = suploaderurl ;
frmupload.submit() ;
}

switch ( errornumber )

case 0 : // no errors
txturl.value = fileurl ;
