Shopify-在选择产品选项时在url中更改变体id

好吧，我是Shopify的新手，所以这可能很容易解决，我只是不“明白”

我认为我使用的是一个旧主题，因为新主题似乎已经有了一个js文件，可以在为产品选择选项时更新URL中的变体ID。我一直想弄明白，但我完全迷路了。我的主题似乎根本没有这样的东西

我一直在用jQuery尝试不同的方法，从选项和

历史记录中获取变量ID值。pushState

可以更改URL中的ID，但这不是最好的解决方案，也不能始终如一地工作，也不是真正的“修复”

虽然我很想把这个主题改成一个新的，有效的主题，但遗憾的是这不是一个选择，我知道这个主题可能很糟糕

以下是网站：
