jQuery-从选择菜单设置和检索cookie

我有一个选择菜单，可以让您选择您喜欢的交货国家。当您选择一个选项时，它会在下面显示相关的国家/地区

我正在尝试使用设置cookie，以便用户始终记住最后的选择。以下是迄今为止我所拥有的，但它不起作用：

我想将select选项的值存储为cookie，然后使用相同的值显示相应的国家/地区信息。这是当前存储的cookie，看起来不正确：

{%220%22:{%22jquery11205649891521717818%22:9}%2C%22length%22:1%2C%22context%22:{%22location%22:{%22href%22:%22https://zed-labz.myshopify.com/pages/delivery%22%2C%22ancestorOrigins%22:{}%2C%22来源%22:%22https://zed-labz.myshopify.com%22%2C%22protocol%22:%22https:%22%2C%22host%22:%22zed-labz.myshopfify.com%22%2C%22主机名%22:%22zed labz.myshopfify.com%22%2C%22端口%22:%22%22%2C%22路径名%22:%22/pages/delivery%22%2C%22搜索%22:%22%22%2C%22哈希%22:%22%22}%2C%22mc嵌入订阅表单%22:{%220%22:{}%2C%221%22:{}}%2C%22选择器%22:%22#deliverycountry1%22}

一些问题：

• 保存jQuery集合，因为$countrycode不是该值：

  var $countrycode = $('#delivery' + $(this).val());
  

• 从cookie中获取值来设置选择的时刻从未出现过

下面是更正的代码：

$(function () {
    $('#country').change(function() {
        $('.box').hide();
        if( Cookies ) {
            Cookies.set('deliveryOption', $(this).val());
        }
        $('#delivery' + $(this).val()).show().siblings().hide();
    });
    // On page load, read out the cookie, and select the corresponding country
    // If no cookie, take country1 as default
    var country = Cookies && Cookies.get('deliveryOption') || 'country1';
    $('#country').val(country).trigger('change');
})

从中看到它

$(function () {
    $('#country').change(function() {
        $('.box').hide();
        if( Cookies ) {
            Cookies.set('deliveryOption', $(this).val());
        }
        $('#delivery' + $(this).val()).show().siblings().hide();
    });
    // On page load, read out the cookie, and select the corresponding country
    // If no cookie, take country1 as default
    var country = Cookies && Cookies.get('deliveryOption') || 'country1';
    $('#country').val(country).trigger('change');
})
