我在我的音乐团体的网站上为部分季票套餐销售创建了一个脚本。用户将选择 4 个音乐会节目，然后为每个所选音乐会节目选择日期。所有这些选择都需要发布到 Paypal 进行处理/购买。我的“添加到购物车”按钮确实会发送到 Paypal，但音乐会节目和日期没有被选中。票房人士需要这些信息。你可以在这里看到我的代码：http: //jsfiddle.net/saraswati/v6Pur/66/
这是HTML：

这是Javascript：

同样，当我单击“添加到购物车”按钮时，它转到 Paypal，描述为“部分订阅（4 场音乐会），常规价格”，它会显示商品价格等。但是，描述也应该显示选择，例如“都铎王朝，9 月 15 日；凯尔特人，1 月 27 日；等等。” 我质疑你们所有人在实现这一目标方面的智慧。谢谢！
