我试图在最后一个应用程序上首先使用它，这样如果它起作用，我也会将它复制到其他领域。还有，有没有什么方法可以将相同的下拉列表重新用于三种不同的选择输入？我认为应该这样做：
<select name="markappliedcountry" id="multi-country" class="dropdown-country" style="width:20%" multiple >
<option value="Afghanistan">Afghanistan</option>
<option value="Albania">Albania</option>
<option value="Algeria">Algeria</option>
<option value="Zambia">Zambia</option>
<option value="Zimbabwe">Zimbabwe</option>
</select>
<input type="text" id="selected_values" name="multiple_selected_values" disabled/>
因此，在问了这个问题并尝试了许多备选方案29天后，我终于找到了答案： 这是我的Html文件：

由于缺少字符限制，我缩短了选择选项。但是，三个选择菜单中有一个拥有所有选项。所以，如果你想的话，你可以复制它们。嗯，有点。。。您已经附上了JSFIDLE示例，您可以在其中看到结果。。。我使用标记名作为选择器，但如果您想在我的项目中使用jQuery Egde，可以将其更改为ID或类。我认为它不起作用，因为我不知道如何使用jQueryEdge，因为上面的java脚本不起作用
