隐藏/显示基于多个下拉选择的行（过滤）

Question

所以我的问题是这样的。我有一张桌子，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，我希望能够随后使用第二个下拉列表进一步过滤该项目，并以其他下拉菜单为准。这是我正在使用的代码，目前独立工作。

<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'); 
    }); 
});
