Dynamic Ajax filter with Laravel implementation

i'm tryng to create a sidebar filters for an e-commerce. I have successfully implemented a infinte scroll pagination, but now i have a problem with filters.

    <ul class="check-box-list">
      <?php $m = 1; ?>
        @foreach($marchi as $marchio)
          <li>
           <input type="checkbox" id="m" class="marchio" name="" data-marchio="" value="" />
          <label for="m">
            <span class="button"></span>
               <span class="count">()</span>
            </label>   
     </li>
 <?php $m++; ?>
     @endforeach   
 </ul>

have this above checkboxes that is generated dynamically. If i click on one of this i can trigger the correct value using this js:

<script type="text/javascript">
$('.marchio').on('click', function() {
      var marchio = $('.marchio:checked').val();
      $.ajax(
        {
            url: '?marchio=' + marchio,
            type: "get",
            beforeSend: function()
            {
                $('.ajax-load').show();
            }
        })
        .done(function(data)
        {
            if(data.html == " "){
                $('.ajax-load').html("No more records found");
                return;
            }
            $('.ajax-load').hide();
            $("#post-data").append(data.html);
        })
        .fail(function(jqXHR, ajaxOptions, thrownError)
        {
              alert('server not responding...');
        });
});

But if i click a 2nd checkbox, the value appended to the ajax url remaining the same, if i uncheck the first remaining the second. I need to pass to the url multiple values of the same checkbox class by appending it to the url. And if some categorie's can have multiple filter's i need the ajax url can accept different ?querystryngs for example by appending ',' separated values once we click on checkboxes. Can someone help me?
