基于两个/三个下拉值的jQuery隐藏文本字段

Question

目前，我一直停留在JQuery脚本上，我想根据两个/三个下拉值匹配使文本字段可见。以下是我的JQuery代码，当“状态”值“已解决”，“原因”值“ [任何]”，泄漏原因“ [任何]”以及原因值是“其他”描述文本字段时，我需要出现。如果以上任何更改值与当前条件都不匹配，则说明文本字段应消失。

$(function () {
  var changeVisibility = function () {
    var statusId = $('#issue_status_id').val();
    if (statusId >= '3') {


      var val2 =$("#issue_custom_field_values_18").val();
      if (val2 == '28' || val2 == '29' || val2 == '30' || val2 == '31' || val2 == '32' || 
      val2 == '33' || val2 == '34' || val2 == '35' || val2 == '36' || val2 == '89') {


       var val3 = $ ("#issue_custom_field_values_19").val();
       if (val3 == '37' || val3 == '38' || val3 == '39' || val3 == '40' || val3 == '41' ||
       val3 == '42' || val3 == '43' || val3 == '96') {

       var val = $('#issue_custom_field_values_26').val();

      if (val == '87') {
        $('#issue_custom_field_values_39').parent().show();
        $('.cf_39').show();
      } else if (val == '94') {
        $('#issue_custom_field_values_39').parent().hide();
        $('.cf_39').hide();
      } else if (val == '81') {
        $('#issue_custom_field_values_39').parent().hide();
        $('.cf_39').hide();
      } else if (val == '82') {
        $('#issue_custom_field_values_39').parent().hide();
        $('.cf_39').hide();
      } else if (val == '83') {
        $('#issue_custom_field_values_39').parent().hide();
        $('.cf_39').hide();
      } else if (val == '84') {
        $('#issue_custom_field_values_39').parent().hide();
        $('.cf_39').hide();
      } else if (val == '85') {
        $('#issue_custom_field_values_39').parent().hide();
        $('.cf_39').hide();
      }
        else if (val == '86') {
          $('#issue_custom_field_values_39').parent().hide();
          $('.cf_39').hide();
          } else if (val == '87') {
            $('#issue_custom_field_values_39').parent().hide();
            $('.cf_39').hide();
      } else {}
    }
  }
  }
  };

  changeVisibility();

  $('#all_attributes').on('change', '#issue_custom_field_values_26 ', function (e) {
    changeVisibility();
  });

  var _replaceIssueFormWith = replaceIssueFormWith;
  replaceIssueFormWith = function (html) {

    _replaceIssueFormWith(html);

    changeVisibility();
  };

});

当选择下拉值时，文本字段也应消失。
