Question

asp select case 问题

<%
dim hytjcount
Function GetStar(hytjCount)
select case hytjCount
case 1
GetStar = "<img src=images/1x.png>"
case (hytjCount>1 and hytjCount<=5)
GetStar = "<img src=images/2x.png>"
case (hytjCount>5 and hytjCount<10)
GetStar = "<img src=images/3x.png>"
case (hytjCount>=10 and hytjCount<=20 )
GetStar = "<img src=images/4x.png>"
case (hytjCount>=21 and hytjCount<=500)
GetStar = "<img src=images/5x.png>"
case else
GetStar = "<img src=images/bullet.gif>"
end select

end function
%>

case 的范围老是显示不准确,该怎么啊? vb 中好像,能用 5 to 10 来表示范围, 在asp 中. 提示有语法错误. .

Answer 1

帮你改了一下代码，你再试试
dim hytjcount
Function GetStar(hytjCount)
select case true
case （hytjCount=1）
GetStar = "<img src=images/1x.png>"
case (hytjCount>1 and hytjCount<=5)
GetStar = "<img src=images/2x.png>"
case (hytjCount>5 and hytjCount<10)
GetStar = "<img src=images/3x.png>"
case (hytjCount>=10 and hytjCount<=20 )
GetStar = "<img src=images/4x.png>"
case (hytjCount>=21 and hytjCount<=500)
GetStar = "<img src=images/5x.png>"
case else
GetStar = "<img src=images/bullet.gif>"
end select
end function

Answer 2

ASP 的CASE 语句中只支持常量列表,如CASE 3,4,5,6,
如果你的程序比较数值范围较宽,建议使用:
IF 比较一 THEN
...
ELSEIF 比较二 THEN
....
ELSEIF 比较三 THEN
....
ELSE
...
END IF
的方式
