我正在尝试以多步骤形式使用验证,当我使用验证时,它在最后一步中可以很好地与输入字段配合使用,但是问题是,在第一步和第二步中,我正在使用单选选项,并且正在尝试在此处使用验证,这样一来,如果不选择任何选项,则无法进行下一步。

一种简单的方法来检查是否选中了特定组中的任何单选按钮,您可以在验证功能内执行以下操作:
$("#msform").submit(function() {
//Your other validations here...
if (document.querySelectorAll('input[name="artist"]:checked').length > 0) {
alert('Artist group has a selection.');
} else {
alert('Artist group does not have a selection.');
}
if (document.querySelectorAll('input[name="event"]:checked').length > 0) {
alert('Event group has a selection.');
} else {
alert('Event group does not have a selection.');
}
}
