Ajax post does not work on mobile

Ajax post does not work on mobile

Hello,

I am creating a filter for my website with ajax and it works correctly from the computer. But when I enter from any mobile (android, ios, etc) it does not show the results. 

The code I use is as follows:

jQuery version: v3.3.1

  1. <script>

  3. $(document).ready(function(){

  5.     filter_data();

  7.     function filter_data()
  8.     {
  9.         $('.filter_data').html('<div class="spinner-border" role="status"></div>');
  10.         var action = 'fetch_data';
  11.         var categoria = get_filter('categoria');
  12.         var etiqueta = get_filter('etiqueta');
  13.         
  14.         $.ajax({
  15.             type:"POST",
  16.             url:"category.php",
  17.             cache: false,
  18.             data:{action:action, categoria:categoria, etiqueta:etiqueta},
  19.             success:function(data){
  20.                 $('.filter_data').html(data);
  21.             }
  22.         });
  23.         
  24.     }

  26.     function get_filter(class_name)
  27.     {
  28.         var filter = [];
  29.         $('.'+class_name+':checked').each(function(){
  30.             filter.push($(this).val());
  31.         });
  32.         return filter;
  33.     }

  35.     $('.common_selector').click(function(){
  36.         filter_data();
  37.     });
  38.     

  40. });
  41. </script>

I find it very strange that it works on PC but not on mobile. What's going on?

I've been looking on the internet but I can't find a solution :/

Sorry for my bad English, I use translator.
