body:

<script type='text/javascript'>
var CSRF_TOKEN = $('meta[name="csrf-token"]').attr('content');                           

$(document).on("click", ".update42" , function() {
var edit_id = 42;
var name = 1 + 1;
    $.ajax({
    url: '/dashboard/post/42',
    type: 'patch',
    data: {_token: CSRF_TOKEN,id: edit_id,download_count: name},
    success: function(response){
        alert(response);
    }
                                                });                                          
}); 
</script>

Answer 1

Just full address then solve

url: 'https:/yoursite.com/dashboard/post/42',

Answer 2

Add this to your script

    var WebURL = {!! json_encode(url('/')) !!}

then use it in your AJAX url

url: WebURL + '/dashboard/post/42',
