根据多个下拉选项隐藏/显示行(过滤)

问题描述

所以我的问题是这个.我有一张桌子，我正在根据一个下拉菜单选择隐藏/显示行.希望有两个菜单一起工作，而不是独立工作.如果我在第一个下拉菜单中选择了一个项目，那么我希望能够在第二个下拉菜单中进一步过滤该项目，以此类推.这是我目前正在独立使用的代码.

So my question is this. I have a table and I am hiding/showing rows based on a dropdown menu selection. What would like to have is the 2 menus working together rather than independently. If I select an item in the first dropdown, I would like to be able then to filter that item further with the second dropdown and so on with any additional dropdown. Here's the code I'm using that works independently currently.

    <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>

推荐答案

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');
    });
});
