javascript - 根据多个下拉选择隐藏/显示行(过滤)

Question

所以我的问题是这样的。我有一个表，我根据下拉菜单选择隐藏/显示行。想要的是 2 个菜单一起工作而不是独立工作。如果我在第一个下拉列表中选择一个项目，我希望能够使用第二个下拉列表进一步过滤该项目，依此类推任何其他下拉列表。这是我正在使用的代码，目前可以独立运行。

    <script>
$(document).ready(function(){
 $('select#age').bind('change',function(){
  if($(this).val()=='Show All'){
   $('td.age').parent().show();
  }else{
   $('td.age').parent().hide();
   $('td.age:contains("'+$(this).val()+'")').parent().show();
  }
  $('#counts').html( $('table.data_table tr:visible').length-1 + ' Registered Kids' )    
 })
  $('select#sport').bind('change',function(){
  if($(this).val()=='Show All'){
   $('td.sport').parent().show();
  }else{
   $('td.sport').parent().hide();
   $('td.sport:contains("'+$(this).val()+'")').parent().show();
  }
  $('#counts').html( $('table.data_table tr:visible').length-1 + ' Registered Kids' )    
 })
})
</script>

String.prototype.replaceAll = function(search, replacement) {
    var target = this;
    return target.replace(new RegExp(search, 'g'), replacement);
};

$(document).ready(function() {
    var ddlFilterTableRow = $('select.ddlFilterTableRow'),
        headerCount = $('#headerCount');
          headerCount.html($('#tableRegisterKids').find('.Row').length + ' Registered Kids');

    ddlFilterTableRow.on('change', function() {
        ddlFilterTableRow.attr('disabled', 'disabled');

        var records = $('#tableRegisterKids').find('.Row');
        records.hide();

        var critriaAttributes = [];
        ddlFilterTableRow.each(function() {
            var $this = $(this),
                $selectedLength = $this.find(':selected').length,
                $critriaAttribute = '';

            if ($selectedLength > 0 && $this.val() != '0') {
                if ($selectedLength == 1) {
                    $critriaAttribute += '[data-' + $this.data('attribute') + '*="' + $this.val() + '"]';
                } else {
                    var $startDataAttribute = '[data-' + $this.data('attribute') + '*="',
                        $endDataAttribute = '"]',
                        $selectedValues = $this.val().toString();

                    $critriaAttribute += $startDataAttribute + $selectedValues.replaceAll(',', ($endDataAttribute + ',' + $startDataAttribute)) + $endDataAttribute;
                }
                critriaAttributes.push($critriaAttribute);
            }
        });

        var $showRecords = records;
        if (critriaAttributes.length > 0) {
            $.each(critriaAttributes, function(i, filterValue) {
                $showRecords = $showRecords.filter(filterValue);
            });
        }
        $showRecords.show();

        headerCount.html($showRecords.length + ' Registered Kids');

        ddlFilterTableRow.removeAttr('disabled');
    });
});
