在do while循环的另一种常用后... Next循环的循环。在do while循环语句重复语句
块的次数不定。重复的陈述或者当条件为真或直到条件变为True。语法如下所示：
Do [While|Until] condition
statements
Loop
Do
statements
Loop [While|Until] condition
在这方面，这个循环内的代码将执行至少一次的情况。在有一个例子：
下面的例子定义了一个循环，开始与i = 0。循环将继续运行，因为我只要小于或等于
10。我将增加1每次循环运行。
Select ActionSelect AllTry It<%
Dim i 'use i as a counter
i = 0 'assign a value to i
Do While i<=10 'Output the values from 0 to 10
response.write(i & "<br >")
i = i + 1 'increment the value of i for next time loop executes
Loop
%>
现在，让我们考虑一个更有用的例子，创建下拉几天，几个月或几年清单。您可以使
用此登记表的代码，例如。
<%
'creates an array
Dim month_array(11)
month_array(0) = "January"
month_array(1) = "February"
month_array(2) = "March"
month_array(3) = "April"
month_array(4) = "May"
month_array(5) = "June"
month_array(6) = "July"
month_array(7) = "August"
month_array(8) = "September"
month_array(9) = "October"
month_array(10) = "November"
month_array(11) = "December"
Dim i 'use i as a counter
response.write("<select name=""day"">" & vbCrLf)
i = 1
Do While i <= 31
response.write("<option value=" & i & ">" & i & "</option>" & vbCrLf)
i = i + 1
Loop
response.write("</select>")
response.write("<select name=""month"">" & vbCrLf)
i = 0
Do While i <= 11
response.write("<option value=" & i & ">" & month_array(i) & "</option>"
& vbCrLf)
i = i + 1
Loop
response.write("</select>")
response.write("<select name=""year"">")
i = 1900
Do Until i = 2005
response.write("<option value=" & i & ">" & i & "</option>" & vbCrLf)
i = i + 1
Loop
response.write("</select>")
%>
