I checked a lot of information from gg and finally found a method in a blog, because of the url path problem.
AddToCart method under common. js

Ajax. call ('flow. php? Step = add_to_cart ', 'goods =' + goods. toJSONString (), addToCartResponse, 'post', 'json ');

AddToCartResponse () method

 

Var cart_url = 'flow. php? Step = Cart ';
