处理多个复选框 [英] Processing Multiple Check Boxes
问题描述
我正在考虑如何在
网页上处理多个复选框。
让我们说我有三个复选框：
cbox1
cbox2
cbox3
我能想到的唯一方法代码可能性如下：
如果cbox1.checked = true则
..........
结束如果
如果cbox2.checked = true那么
.......
结束如果
如果cbox3.checked = true那么
.......
结束如果
如果cbox1.checked = true且cbox2.checked = true则
.......
结束如果
如果cbox1.checked = true且cbox3.checked = true则
.......
结束如果
而且If / End IF会永远持续下去！
正如你所看到的，如果我有大约8个复选框，这样做可能会导致
到大量的编码。我确定有更好，更简单的方式，
对吗？我想过使用一个精选案例，但这不会好多了我不会想到。
该应用程序是一个运行的查询对于访问
数据库中的单个表。每个复选框代表他们可以选择的每个字段，以便在表格或其他样式报告中显示
。
TIA，
吉姆
I''m having dificulty figuring out how to process multiple check boxes on a
web form.
Let''s say I have three check boxes:
cbox1
cbox2
cbox3
The only way I can think of to code the possibilities is something like:
If cbox1.checked = true then
..........
End if
If cbox2.checked = true then
.......
End If
If cbox3.checked = true then
.......
End if
If cbox1.checked = true and cbox2.checked = true then
.......
end if
If cbox1.checked = true and cbox3.checked = true then
.......
end if
And the If/End IFs go on forever!
As you can see, if I have around 8 check boxes, doing it this way could lead
to tremendous amounts of coding. I''m sure there''s a better, easier way,
right? I thought of using a select case but that wouldn''t be much better I
don''t think.
The application is a query that runs against a single table in an access
database. Each check box represents each field they could chose from to show
up in a table or other style report.
TIA,
Jim
推荐答案
为什么不这样做：
dim c as integer = 0
如果cbox3.Checked = True则c = 1
如果cbox2.Checked = True则c + = 2
如果cbox1.Checked =真然后c + = 4
选择案例c
案例0''没有支票
案例1''cbox 3
案例2''cbox 2
案例3''cbox 2& 3
案例4''cbox 1
案例5''cbox 1& 3
案例6''cbox 1& 2
案例7''cbox 1,2，& 3
结束选择
是的，这是古老的...但我来自Applesoft Basic背景:)

Why not do something like:
dim c as integer = 0
if cbox3.Checked = True then c = 1
if cbox2.Checked = True then c += 2
if cbox1.Checked = True then c+=4
Select Case c
Case 0 ''No checks
Case 1 ''cbox 3
Case 2 ''cbox 2
Case 3 ''cbox 2 & 3
Case 4 ''cbox 1
Case 5 ''cbox 1 & 3
Case 6 ''cbox 1 & 2
Case 7 ''cbox 1,2, & 3
End Select
Yeah, it''s archaic...but I come from an Applesoft Basic background :)

那么为什么你需要诸如
如果cbox1.checked = true而cbox2.checked = true那么......
你不能只是建立你的查询检查每个复选框

Then why do you need conditions such as
If cbox1.checked = true and cbox2.checked = true then...
Can''t you just build up your query by checking each checkbox
in turn?

那为什么你需要条件，如
如果cbox1.checked = true而cbox2.checked = true那么......
你不能通过勾选每个复选框来建立你的查询
反过来？

我还是很喜欢编程，所以仍然想要编写代码
技术建立。我从来没有使用过复选框。
当你说你不能通过勾选每个复选框来建立你的查询
in转过来？，我不确定你的意思。你能举个例子吗？
谢谢Jan，
Jim
I''m still pretty new to programming so still trying to get some coding
techniques established. I''ve never worked with check boxes.
When you say "Can''t you just build up your query by checking each checkbox
in turn?", I''m not sure what you mean. Can you give me an example?
Thanks Jan,
Jim
