如何使用jQuery使select2的必填字段为false？我想使用jQuery使每个select2都要求= false并将其禁用。
我尝试了这个......但是$('#accodeformheader').find('input, select').attr('required', false);不起作用。 有没有办法使select2的“required”= false？

如果您不需要，可以简单地删除“required”属性
$('select').removeAttr('required');如果您想重新设置，请按照以下步骤进行：
$('select').prop('required', 'required');如果您想根据id或类删除特定的select2下拉菜单，请按照以下步骤进行：
$('#your_id_name').removeAttr('required');使用类名：
$('.your_class_name').removeAttr('required');同样，您可以根据id和类进行设置，如下所示：
$('#your_id_name').prop('required', 'required');使用类名：
$('.your_class_name').prop('required', 'required');我希望我理解您的问题并给出了正确的答案。
