ASP中的条件语句和循环语句

Posted 2023-03-27

谁介绍一下ASP中的条件语句和循环语句，小弟初学asp找不到系统的知识最好给点例子

参考技术A 1) if...then if 条件为真 then 语句块 end if+++++++++++++++++++++++++++++++++ 2) if...then...else +++++++++++++++++++++++++++++++++ 3) select case select case a(变量) case a=1 语句块1 case a=2 语句块2 ... .... end select +++++++++++++++++++++++++++++++++ VBscript 循环语句1)do...loop do while 条件 语句块 loop--------------------------------- do 语句块 loop while 条件--------------------------------- do until 条件 语句块 loop---------------------------------do 语句块loop until 条件+++++++++++++++++++++++++++++++ 2)while...wend +++++++++++++++++++++++++++++++ 3)for...next +++++++++++++++++++++++++++++++ 4)for each...next +++++++++++++++++++++++++++++++ 5)exit exit doexit forexit functionexit sub +++++++++++++++++++++++++++sub 和 function 是过程 参考技术B ASP中的IF和循环语句和VB大致相同的。IF例子：<%
b=5
if b>=5 then
response.Write"我会了"
else
response.Write"我不会"
end if
%>if else end if固定用法循环例子：<div align="center">
<%
for i=0 to 9
a=a&"口"
response.Write(a)
response.Write("<br>")
next
%>for next固定用法要全面了解建议看看视频教程！ 参考技术C 1.条件语句：处理条件分支逻辑结构的算法语句叫条件语句.条件语句分为if语句和case语句.if语句的一般格式是：if 表达式 语句序列1；else 语句序列2end 2.if语句最简单的格式 if表达式 语句序列1； end
