问题描述
我有收音机和选择/输入的组合：
http：// sneleopard .dk / radio.html
当用户
对字段1执行某些操作时，是否有自动设置广播1的javascript，以及自动设置无线电2，当
用户对字段2执行某些操作时？

是的，但它有一个问题：你有车吗？这可以从阿姆斯特丹开往巴黎吗？
它在javascript中是非常基本的，但是你找不到''javascript''
将在你当前的设置中同时工作。
我知道我现在还不是很有帮助。 :-)
你需要做什么/学习：
- 命名元素
- onChange eventhandler来检测某个字段的变化。
- 如何更换一个radiobuttongroup
类似于：
document.forms [''yourformname'']。radiogroupname [0] .checked =祝你好运;
祝你好运。
问候，

Yes, but it a question like: "Do you have a car that can drive from
Amsterdam to Paris?"
It is very basic in javascript, but you will not find ''a javascript'' that
will work at once in your current setup.
I know I am not very helpfull untill now. :-)
What you need to do/study:
- naming formelements
- onChange eventhandler to detect a change in some field.
- how to adres a radiobuttongroup
something like:
document.forms[''yourformname''].radiogroupname[0].checked = true;
Good luck.

是否有自动设置收音机1的javascript，当用户
时使用字段1的东西，并自动设置收音机2，当
用户对字段2执行某些操作时？

您需要清楚地解释您的要求。一个单选按钮应该总是选择
，默认选择哪一个？
所选按钮是否代表最后一个被更改的字段？
或者，如果字段1更改，则按钮1会被选中;如果字段2更改，则按钮2会更改吗？在这种情况下，是否应同时选择两者？如果是这样，那么他们可能应该是复选框而不是单选按钮。
进一步的帮助取决于获取更多信息。

You need to clearly explain your requirements. One radio button should
always be selected, which one should be selected by default?
Should the selected button represent the last field that was changed?
Or does button 1 get selected if field 1 changes and button 2 if field 2
changes? Should both be selected at the same time in this case? If so,
then they probably should be checkboxes not radio buttons.
Further help is dependant on getting more information.

我听起来不是那么愚蠢！
默认应该是收音机2.
不，这不是我想要的复选框。 radiocheck将随着字段的变化而改变。所以Rob建议：如果字段1改变则按钮1获得
如果字段2改变则选择按钮2
I''m not so stupid as I sound!
The default should be radio 2.
No it''s not checkboxes I want. The radiocheck shall change following
the changes in the fields. So it is what Rob suggests: button 1 get
selected if field 1 changes and button 2 if field 2 changes.
