Parsley验证复选框，该复选框没有必需的属性，但无法验证具有的选择

Question

在下面的代码中，我有一个带有2个选择字段的表单，当复选框被选中或未被选中时，会根据状态显示。。

在jQuery中，我根据选择字段设置required的属性；"活动"；。我的复选框没有必需的属性集，实际上我已经主动尝试将其作为Parsley版本的文档集排除在脚本中>2.1，并在两种切换模式中设置$("#SystemMessageChk").attr('required', false)，但无论我做什么，当我选中复选框并提交表单时，它仍然会验证复选框，而不是活动选择。

有人有修复的想法吗？

$(document).ready(function() {
$(function() {
$("#SystemMessageChk").click(function() {
if ($(this).is(":checked")) {
$("#MessageSystemDIV").show();
$("#MessageSpecificUserDIV").hide();
$("#MessageSystemType").attr('required', true);
$("#MessageReceipients1").attr('required', false)
$("#SystemMessageChk").attr('required', false)
} else {
$("#MessageSystemDIV").hide();
$("#MessageSpecificUserDIV").show();
$("#MessageSystemType").attr('required', false)
$("#MessageReceipients1").attr('required', true);
$("#SystemMessageChk").attr('required', false)
}
});
});
$('#MessageSystemType').selectpicker();
$('.js-example-basic-multiple').select2({
placeholder: 'Vælg modtager(e)...'
});
});

解决方案是删除$("#SystemMessageChk").attr('required', false)并将$("#MessageReceipients-errors").html("");添加到第一个切换中，换句话说，这是一个清除错误文本的问题。

工作代码为：

$( document ).ready(function() {
$(function () {
$("#SystemMessageChk").click(function () {
if ($(this).is(":checked")) {
$("#MessageSystemDIV").show();
$("#MessageSpecificUserDIV").hide();
$("#MessageSystemType").attr('required',true);
$("#MessageReceipients1").attr('required',false);
$("#MessageReceipients-errors").html("");                    
} else {
$("#MessageSystemDIV").hide();
$("#MessageSpecificUserDIV").show();
$("#MessageSystemType").attr('required',false);
$("#MessageReceipients1").attr('required',true);              
}
});
});
$('#MessageSystemType').selectpicker();
$('.js-example-basic-multiple').select2({
placeholder: 'Vælg modtager(e)...'
});
});
