Question

我是asp的新手。这是我的代码：

response.write("<script>")
dim counter: counter = 0
do until rs.EOF
  for each x in rs.Fields
    counter = counter + 1
    response.write "var CC" & counter & "=" & x.value & ";"
  next
  rs.MoveNext
loop
response.write("</script>")

这当前从我的DB返回两列：

<script>var CC1=ALFKI;var CC2=13579;var CC3=ALFKI;var CC4=246;</script>

我只希望返回第二列，即数字（13579＆amp; 246）。

我应该改变什么？

Answer 1

根据您的柜台提供IF声明。

for each x in rs.Fields
    counter = counter + 1
    if(counter = 1) then
      response.write "var CC" & counter & "=" & x.value & ";"
    end if
next

Answer 2

Not sure I should be answering this，但要循环，只有write out on the even iteration使用Mod()来测试余数。

response.write("<script>")
dim counter: counter = 0
do until rs.EOF
  for each x in rs.Fields
    counter = counter + 1
    'Use Mod() to check counter is even
    If counter Mod 2 = 0 Then response.write "var CC" & counter & "=" & x.value & ";"
  next
  rs.MoveNext
loop
response.write("</script>")

Answer 3

试试这个

response.write("<script>")
dim counter: counter = 0
do until rs.EOF
  for each x in rs.Fields
    counter = counter + 1
    if IsNumeric(x.value) then
        response.write "var CC" & counter & "=" & x.value & ";"
    end if
  next
  rs.MoveNext
loop
response.write("</script>")

诀窍是检查"If IsNumeric"然后做你想做的事。
