以下是我的表单 HTML 代码。此表单包含一些国家/地区字段，这些字段是多个下拉选择输入。

else

</body>
</html>
我试图首先在“应用国家”(最后一个)上使用它，这样如果它有效，我也会将其复制到其他领域。另外，有什么方法可以为三个不同的选择输入重复使用相同的下拉列表吗？
最佳答案
我认为应该可以完成这项工作:
<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/>
JS:
$(document).ready(function() {
$('select').on('change', function() {
$('input').val($(this).val());
});
});
关于javascript - 我想将我从多保管箱中选择的值显示到禁用的文本字段中，但我无法做到这一点。请告诉我我缺少什么，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/48802840/
