我正在创建一个网页，用户可以在其中从数据库中删除信息，并且我从数据库中收到一条错误消息，说明这一点。

Microsoft JET 数据库引擎错误“80040e14”

查询表达式“ID=”中的语法错误（缺少运算符）。

/courses/benv/2410/2013s2/3420384/assign3/delete.asp，第 50 行

我相信这是因为有一个值应该由表单传递但丢失了。但是，我看不到我在哪里失踪。

这是网页代码。第 50 行处于第 2 阶段。

<% option explicit %>
<html>
<head>
</head>
<body>
  <!--#include file="dbconn.asp"-->
  <!--#include file="header.asp"-->
  <%
  dim stage, s, sql, info
  stage = request.form("stage")
  if stage = "" then stage=1

  '------------------------------------------------------------------
  if stage = 1 then
  '------------------------------------------------------------------

    '--- get all the posts
    '            0      1               2         3
    SQL="SELECT ID, projectName, description, Created"&_
    " FROM ProjectsTable"&_
    " ORDER BY ID"
    set info=conn.execute(SQL)

    '--- create a radio-button list of the current posts
    response.write "<br>" &_

    info.movenext
    loop until info.eof
    response.write "<input type=""submit"" value=""Delete Post!"">" &_
    "</form>"

  conn.execute(sql)

  response.write  "The specified suburb has been deleted."

我认为问题出在这一行：

response.write "<input type=""radio"" name=""posttobedeleted" &_
    " value="""&info(0)&""">"&info(1) &_
    " "&info(2)&" "& info(3) & "<br>"

尝试将其更改为：

response.write "<input type=""radio"" name=""posttobedeleted"" value=""" &_
info(0) & """>" &_
info(1) &_
" " & info(2) & " " & info(3) & "<br>"

说明：我认为通过分隔“”你已经破坏了单选按钮的正确初始化。我建议您在 Firefox 中安装 FireBug 或其他东西，并为您的单选按钮“检查元素”
