Question

ASP判断语句应该怎么写

比如当A=1时 显示图片1 A=0时 显示图片2

Answer 1

条件不多时用：
<%
if a=0 then
response.write "<img src=""1.jpg"" />"
elseif a=1 then
response.write "<img src=""2.jpg"" />"
end if
%>

条件比较多时也可以这样用：
<%
select case a
case 0
response.write "<img src=""1.jpg"" />"
case 1
response.write "<img src=""2.jpg"" />"
case 2
response.write "<img src=""3.jpg"" />"
case 3
response.write "<img src=""3.jpg"" />"
end select
%>
