How to check data inserted or deleted in pivot after toggle method

• Return json response after toggle method on pivot table

  $user = User::find($userId);
  $roleId = $request->id;
  $response = $user->roles()->toggle($roleId);
  return response()->json(['success'=>$response]);
  

  The toggle method returns an object if the new record is created in the pivot table, else it returns 1 as a response after the toggle method deletes the existing record. Basically, the toggle method deletes the record if the record already exists in it, else insert the new record.

• JQuery check the object is empty or not in HTML page on ajax call

  //Anchor tag to get the role id on click it
  <a href="javascript:void(0)" class="add-role" data-id="1">  Role  </a>
  
  //Call ajax on click anchor tag
  $('.add-role').click(function(){    
      var id = $(this).data('id');
      $.ajax({
          type:'POST',
          url:'/ajax-role',
          data:{id:id},
          success:function(data){
              if($.isEmptyObject(data.success.attached)){
                  console.log('Record is deleted from pivot table');
              }else{
                  console.log('Record is created in pivot table');
              }
          }
      });
  });
  

  You can easily check that the object is empty or not in HTML using the jquery method $.isEmptyObject(). It will return true if the data is an empty object.
