我正在使用下面的 jQuery 来验证多个组，但是在将我的代码更新为此链接中的方法之后：Jquery .validate require_from_group，我遇到了一个问题，除了第二组之外的所有内容都经过验证，这之前工作正常。
$("#contact-form").validate({
groups: {
links: "link_fb link_yt link_db",
checkboxes: "tracking mixing mastering reamping editing other"
},
rules: {
'link_fb': {
require_from_group: [1, ".link_group"]
},
'link_yt': {
require_from_group: [1, ".link_group"]
},
'link_db': {
require_from_group: [1, ".link_group"]
},
'tracking': {
require_from_group: [1, ".checkbox_group"]
},
'mixing': {
require_from_group: [1, ".checkbox_group"]
},
'mastering': {
require_from_group: [1, ".checkbox_group"]
},
'reamping': {
require_from_group: [1, ".checkbox_group"]
},
'editing': {
require_from_group: [1, ".checkbox_group"]
},
'other': {
require_from_group: [1, ".checkbox_group"]
}
},
errorPlacement: function (error, element) {
console.log(element[0])
if(element[0].value === "tracking")
{
error.insertBefore(element);
}
else {
error.insertAfter(element);
}
}
});
这是表单的标记：

有人有什么想法吗？

编辑：
这是最新的 require_from_group 方法（不在 github 主分支中），您会看到我的问题：
jQuery.validator.addMethod("require_from_group", function(value, element, options) {
var numberRequired = options[0];
var selector = options[1];
var fields = $(selector, element.form);
var filled_fields = fields.filter(function() {
// it's more clear to compare with empty string
return $(this).val() != "";
});
var empty_fields = fields.not(filled_fields);
// we will mark only first empty field as invalid
if (filled_fields.length < numberRequired && empty_fields[0] == element) {
return false;
}
return true;
// {0} below is the 0th item in the options field
}, jQuery.format("Please fill out at least {0} of these fields."));
