The x variable in your code will be a Field object. A field object does not have an id property hence the error. I suspect that id, title and info are actually the names of the fields you want to use. Hence your code should look like this:

代码中的x变量将是Field对象。字段对象没有id属性,因此出错。我怀疑id,title和info实际上是你想要使用的字段的名称。因此,您的代码应如下所示:

grs.Open "SELECT id, title, info FROM gells", db  
do until grs.EOF  
    response.write "<table style='margin-bottom:8px;'><tr><td style='vertical-align:top; padding-top:4px;'><img src='gells/uploads/gelthumbs/" _
        & Server.URLEncode(grs("id")) _
        & "_gelthumb.jpg' style='border:1px solid #FFFFFF;' /></td><td style='vertical-align:top; padding-left:4px; text-align:justify;'><strong>" _
        & Server.HTMLEncode(grs("title")) _
        & "</strong><br />" & Server.HTMLEncode(grs("info")) _
        & "</td></tr><tr><td colspan='2' style='text-align:right; padding-top:4px;'><a href='gells.php?gelsid=" _
        & Server.URLEncode(grs("id")) _
        & "' ><img src='gells/viewgell.png' style='border:none;' /></a></td></tr></table>"
    grs.MoveNext  
loop  
grs.close

Note the SQL only includes the fields you need, also never send unencoded data directly from the DB.

请注意,SQL仅包含您需要的字段,也不会直接从数据库发送未编码的数据。
