Answer 1

in Ihrem Controller angezeigt werden:

public function removeCart() 
{ 
.. 
$data = array(
'count'=>$this->cart->contents(),//modify this to return count. 
'cart'=> $this->view_shoppingcart()//modify this to return the html output. 
); 

echo json_encode($data); 
} 

in Ihren Ajax-Code:

function remove_cart(itemid) 
{ 
     $.ajax({ 
      type: 'POST', 
      url: '<?php echo site_url("ajax_controller1/remove_cart/'+itemid+'")?>', 
      data: { id:itemid }, 
      success:function(response){ 
      response= JSON.parse(response); 
      $("#shoppingcart_container").html(response.cart); 
      $("#count_container").html(response.count); 

    } 
    }); 

}
