view.phtml page in template
 

productAddToCartForm.submit = function(button, url) {
            if (this.validator.validate()) {
                var form = this.form;
                var oldUrl = form.action;

                if (url) {
                   form.action = url;
                }
                var e = null;

                }

                if (button && button != 'undefined') {
                    button.disabled = true;
                }
            }

                }
                var data = jQuery('#product_addtocart_form').serialize();
                data += '&isAjax=1';
                try {
                    jQuery('.product-shop').prepend('<div class="ajax_loader">&nbsp;</div>');
                    jQuery.ajax({
                          url: url,
                          dataType: 'json',
                          type : 'post',
                          data: data,
                          success: function(data){

                          }
                    });
                    setTimeout(function(){
                        getcartdata(this.form);
                    },1000);
                } catch (e) {
                }
                this.form.action = oldUrl;
                if (e) {
                    throw e;
                }
            }
        }.bind(productAddToCartForm);

How to get only cart sidebar Layout block in magento

In your controller you could try something like this:

$block = $this->getLayout()->createBlock('checkout/cart_sidebar');

$block->setTemplate('checkout/cart/sidebar.phtml');

Depending on your configuration (Config -> Checkout -> Shopping Cart Sidebar),

you can render the template with  

$block->toHtml(); 

If you use a custom template, you could ignore the config value so it renders anytime.
