使用Curry jQuery插件进行货币转换。我使用jscookie将所选货币存储在cookie中。一切都很完美，但是当重新加载页面时，HTML元素不会随所选的选项值而改变。它只会在我手动点击它时发生变化。

以下是curry.js的修改版

答案 0 :(得分：0)
在你的
中jQuery(document).ready(function() {
如果未定义cookie，则设置变量
if (typeof CookieSet === "undefined") {
你需要添加：
Cookies.set('site_currency', savedCurrency, { expires: 7, path: '/' });
Cookies.set('site_rate', savedRate, { expires: 7, path: '/' });
