javascript - 停止在表单中发布隐藏的选择字段

Question

我有几个下拉菜单，用户可以选择第一个选项，然后根据所选的选项，将出现一个新的下拉菜单。

这两个值需要发布，但现在所有选择下拉列表都已发布，甚至是隐藏的。我怎样才能防止这种情况发生？

我的jquery:

// linking values to dropdowns
var placesLists = {
'uiteten': '#uiteten',
'snackensnoepen': '#snackensnoepen',
'drankje': '#drankje',
'evenement': '#evenement',
'stappen': '#stappen',
'cultuur': '#cultuur',
'sightseeing': '#sightseeing',
'kids': '#kids',
'informatie': '#informatie',
};

$('select[name=watwiljedoen]').change(function(){
  //hide all extra lists
  $('.hide').hide();

  //get current value
  var value = $(this).val();

  //if there is a list for this value, show it
  if (value in placesLists){
    $(placesLists[value]).show();
    $(placesLists[value]).removeClass('dropdownwwjdnonactive');
    $(placesLists[value]).addClass('dropdownwwjd');
  }
});

.hide{
  display:none;
}

  <input type="submit" class="wwjdbutton" name="button" value="Bekijk resultaten">
  <!-- <button type="button"  name="button">Bekijk resultaten</button> -->
</form>

我只想发布可见的标签，而不是全部。

改变

//隐藏所有额外列表
$('.hide').hide();

到

$('.hide').hide().attr('禁用','禁用);
