Question

我有一组小表，每个小表都有一个唯一的ID，一个类将它们加载为display none。

然后我需要一个选择器，访问者可以选择一个国家/地区，并且包含匹配送货方式的相关表格将删除隐藏的类。

我已经把基础知识搞得一团糟了，但是这个jQuery已经让我陷入了困境。

        $(function(){
          // bind change event to select
          $('#country_selector').on('change', function () {
              var shippingMethod = $(this).val(); // get selected value
              if (shippingMethod) { // 
                  
              }
              return false;
          });
        });

table.load-hidden{

display:none;
}

<select id="country_selector">
  <option value="" selected="selected">Select your Country</option>
  <option value="australia-post-ground-parcel">Australia</option>
  <option value="usps-first-class-mail-international">Canada</option>
  <option value="australia-post-pack-and-track-international-parcel">New Zealand</option>

Answer 1

由于选项值与ID

匹配，因此应该是直截了当的

$(function() {
    $('#country_selector').on('change', function() {
        $('.load-hidden').hide();
        $('#' + this.value).show();
    });
});
