将价格为0的产品添加到购物车到bigcommerce

Question

将某产品的价格设为0.00，并尝试下该产品的订单。它使我们能够进入购物车并继续结帐。

$("#product_price_zerovalidation").on('DOMSubtreeModified', function () {

var price = $('#product_price_zerovalidation').text().replace("$", "");
   if(price == '0.00'){
       $("#form-action-addToCart").css({"background-color": "grey", "pointer-events": "none","border": "gray"});
   }else{
       $("#form-action-addToCart").css({"background-color": "#45b3e9","pointer-events": "auto"});

   }
});
