我已经提交了 patch 这不会受到当前版本所带来的问题的影响(即“Required”选项在其他字段上停止正常工作,关于当前版本的问题的讨论正在进行 github .

例 http://jsfiddle.net/f887W/10/

jQuery.validator.addMethod("require_from_group", function (value, element, options) {
var validator = this;
var minRequired = options[0];
var selector = options[1];
var validOrNot = jQuery(selector, element.form).filter(function () {
    return validator.elementValue(this);
}).length >= minRequired;

// remove all events in namespace require_from_group
jQuery(selector, element.form).off('.require_from_group');

//add the required events to trigger revalidation if setting is enabled in the validator
if (this.settings.onkeyup) {
    jQuery(selector, element.form).on({
        'keyup.require_from_group': function (e) {
            jQuery(selector, element.form).valid();
        }
    });
}

if (this.settings.onfocusin) {
    jQuery(selector, element.form).on({
        'focusin.require_from_group': function (e) {
            jQuery(selector, element.form).valid();
        }
    });
}

if (this.settings.click) {
    jQuery(selector, element.form).on({
        'click.require_from_group': function (e) {
            jQuery(selector, element.form).valid();
        }
    });
}

if (this.settings.onfocusout) {
    jQuery(selector, element.form).on({
        'focusout.require_from_group': function (e) {
            jQuery(selector, element.form).valid();
        }
    });
}

return validOrNot;
}, jQuery.format("Please fill at least {0} of these fields."));
