ecshop中ajax的调用原理介绍

Ajax.call( 'user.php?act=is_registered', 'username=' + username, registed_callback , 'GET', 'TEXT', true, true );
Ajax.call('user.php?act=return_to_cart', 'order_id=' + orderId, returnToCartResponse, 'POST', 'JSON');

goods.quick = quick;
goods.spec = spec_arr;
goods.goods_id = goodsId;
goods.number = number;
goods.parent = (typeof(parentId) == "undefined") ? 0 : parseInt(parentId);
Ajax.call('flow.php?step=add_to_cart', 'goods=' + goods.toJSONString(), addToCartResponse, 'POST', 'JSON');

include_once('includes/cls_json.php');
$_POST['goods'] = json_str_iconv($_POST['goods']);
