动态选择列表问题。 [英] Dynamic Pick list question.
问题描述
您好，
我想知道是否有人可以指出我正确的方向
弄清楚如何创建动态表单。我一直在开发perl和oracle中的
程序，并且最近已经切换到php。
我需要创建一个包含五个独立选择列表中的四个的表单每个选项列表中的每个项目取决于用户以前的输入。
如果用户选择福特，那么Taurus，Ranger，焦点，.etc显示
在下一个选择列表中然后用户选择Ranger和2轮驱动，4
轮驱动等显示在下一个选择列表框中等等。
如果每次用户输入后屏幕都被刷新，我知道怎么做。什么
我想弄清楚如何让屏幕自动更新
每个选择列表而不刷新整个屏幕。
任何帮助或指示会很棒！
谢谢
马克

马克，
你可以''在PHP中执行此操作。 PHP只是客户端;要做到这一点没有
刷新会要求所有信息都发送到客户端，然后
由客户端语言（如javascript）处理。

对，
我知道你必须使用服务器端的javascript，但是如何？...

不，javascript客户端。所以你需要使用像PHP
这样的服务器端处理，以及javascript用于客户端。

Hello,
I am wondering if someone could point me in the right direction to
figure out how to create a dynamic form. I have been developing
programs in perl and oracle and have recently switched to php.
I need to create a form that has four of five seperate pick list on it.
Each item in each of the pick list depend on the users previous entry.
For instence if the user picks Ford then Taurus, Ranger, Focus,.etc show
up in the next pick list then the user picks Ranger and 2 wheel drive, 4
wheel drive, etc show in the next pick list box on so on.
I know how to this if the screen is refresed after each user entry. What
I would like to fugure out how to make the screen automatically update
each pick list and not refreshing the whole screen.
Any help or instruction would be great!
Thanks
Mark

Mark,
You can''t do this in PHP. PHP is client-side only; to do it without
refreshing would require all the info be sent to the client, then
processed by a client-side language such as javascript.

No, javascript it client side. So you need to use something like PHP
for the server side processing, and javascript for the client side.
