javascript - 仅当 div 未隐藏时才需要在表单中输入以发送电子邮件

问题描述

我目前有一个具有许多不同输入的表单。有两组单选按钮，当它们被选中时，会显示两个不同的 div 以及所需的输入。问题是，在提供所有必需的输入之前，我无法发送电子邮件，即使是未显示的输入也是如此。我已经修复了第一次出现的名称=（tick），但不知道如何在通过选择单选按钮（选项）显示 div 时仅显示（要求）所需的消息。

解决方案

也许您可以创建一个“非活动”选项，该选项在选择选择B时在选择A上填充。例如：

<input style="display: none;" type="checkbox" name="tick" value="inactive">

然后（伪代码）：

when ( input A :selected ) { activate( input B "inactive" ) }

反之亦然。这应该允许您过滤掉不活动的表单字段，并允许用户在需要所有可见和不可见字段的情况下提交表单——而他们无法选择空选项。
