尝试

$('div.items:first').show();
$('div.items').children('input').on('change', function(){
    var parent = $(this).parent('div').data('name');
    var path = $(this).parent('div').data('show');
    var valid = true;
    $(this).parent('div.items').children('.required').each(function (index) {
        if ($(this).val() == '') {
            valid = false;
            return false;
        }
    });
    if(valid){
        console.log('ok')
    }
});
