验证隐藏的多复选框/输入字段

【中文标题】验证隐藏的多复选框/输入字段【英文标题】：Validation of Hidden Multi-Checkbox/Input fields 【发布时间】：2017-11-23 11:54:18 【问题描述】：为了处理带有多个可选复选框的字段验证，我使用了 webshims polyfill。
表单具有隐藏/取消隐藏表单部分的复选框。
最初的任务是仅在隐藏部分变得可见时验证/要求隐藏部分。
我最初的想法是使用 webshims polyfill 的功能，仅在选中与使该字段可见相关联的复选框时才需要隐藏字段。
问题 #1： 一些隐藏部分包括这些需要验证的多复选框类型字段。如何让这些字段利用 webshims 的 data-grouprequired="" 功能，以便验证这些多复选框字段？
问题 #2： 有一个隐藏部分 (Registries/id=div3) 包含 5 个输入文本字段 - 最终用户只需填写这些字段中的至少一个。我该如何做到这一点，当这个隐藏部分变得可见时，至少需要 5 个字段中的一个来验证表单？
或者，如果有更好的解决方案，我很想学习。我对此很陌生。
这是表单中的相关代码：
<script>
webshim.setOptions('forms',
lazyCustomMessages: true,
addValidators: true
);
webshim.polyfill('forms forms-ext');
</script>
<script>
function addTableRow()
var $tableRow = $('tr.model-row:first-child');
var $clonedRow = $tableRow.clone().show();
$('#stmember').append($clonedRow);
function myDeleteFunction()
var $memberTRs = $('tr', '#stmember');
// If rowcount === 1, hide first row, don't remove it!!
var rowCount = $memberTRs.length;
if (rowCount === 1)
$('tr.model-row:first-child').hide();
return;
$memberTRs.last().remove();
jQuery(function()
$('#delete').click(function()
myDeleteFunction();
);
$('#add').click(function()
addTableRow();
);
);
</script>
<script type="text/javascript">
function showMe (it, box)
var vis = (box.checked) ? "block" : "none";
document.getElementById(it).style.display = vis;
</script>

【问题讨论】：
【参考方案1】：最终我自己想通了。禁用所有隐藏字段。让它们在变得可见时启用。对于多个文本字段，能够使用来自 webshims polyfill 的 data-grouprequired，但必须创建自定义错误消息。
