Question

ASP循环数组元素出错

keywArr=split(keyw,",")
for i=0 to ubound(keywArr)
tit=keywArr(i)
'xx=conn.execute("select id,tit from tags where tit='"&tit&"'")(0)
readList=readList&"<a href=search-"&xx&".html>"&tit&"</a> | "
next
这段代码不知道哪里错了，请达人帮我。其中注释掉的部分删除后正常，但我需要那个id故不能删除。另外，如果修改成
xx=conn.execute("select id,tit from tags")(0)
xx=conn.execute("select id,tit from tags where id=1")(0)
xx=conn.execute("select id,tit from tags where tit='PS'")(0)等都是正常的。且这个变量tit也是真实有效的（有输出文字部分）。加cStr也无效………………

下面这个是不是也是相同原因造成？http://zhidao.baidu.com/question/301414114.html
上面打错了，for i=0 to ubound(keywArr)-1

Answer 1

这是我的测试代码
你看看
<!--#include file="conn.asp" -->
<%
on error resume next
keyw = "腾讯,新浪,百度,人人"
keywArr=split(keyw,",")
for i=0 to ubound(keywArr)
tit=keywArr(i)
xx=conn.execute("select NewsUrl,Title from News where Title='"&tit&"'")(0)
if err=0 then
readList=readList&"<a href="&xx&">"&tit&"</a> | "
end if

next
response.Write(readlist)
conn.close
set conn = nothing
%>
你错在当tit在数据库中不存在时读不出数据的，就会出错，所以要加上on error resume next并且捕获错误，然后再输出 ,不出错的情况下error=0

Answer 2

改为：
xx=conn.execute("select id,tit from tags where tit="&tit&")(0)
另外，用split函数时，数组要定义成动态数组

Answer 3

keywArr=split(keyw,",")
for i=0 to ubound(keywArr)
tit=keywArr(i)
xx=conn.execute("select top 1 id,tit from tags where tit='"&tit&"'")(0)
readList=readList&"<a href=search-"&xx&".html>"&tit&"</a> | "
next
