没有 JQUERY!我有两个单选按钮，出于某种原因我可以同时选择它们，但我只想选择一个。例如，如果您选择有一个婴儿，您可以选择两个单选按钮。有没有简单的方法来解决这个问题？有人可以通过修复我的代码中的错误来帮助我实现这一目标吗？

最佳答案

您没有名字，所以您可以同时选择它们。给他们一个相同的名字!浏览器只会让用户选择一个。

<input type="radio" name="radiobtn" id="rd1" value="" onclick="showChoice(this)"/>
<input type="radio" name="radiobtn" id="rd2" value="" onclick="showChoice(this)"/>
