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。

                <!-- Mark Applied Country  -->


        <b style="text-height:50%">Mark Applied Country:</b><br>

        <select name="markappliedcountry" id="multi-country" class="dropdown-country" style="width:20%" multiple >

            <option value="Afghanistan">Afghanistan</option>
            <option value="Albania">Albania</option>

        <br><br><br>
        <input type="text" id="selected_values" name="multiple_selected_values" disabled/><br/><br/>

        <input type="submit" value="Submit">
      </form>
    </div>

    <script>
    function disableNo() {
        document.getElementById("marknocountry").required = false;
        document.getElementById("marknodate").required = false;      
    }

    function disableYes() {
        document.getElementById("markyescountry").required = false;
        document.getElementById("markyesdate").required = false;
        document.getElementById("markyesproof").required = false;      
    }


    var selText;
    $('select').on('change', function() {
        selText ="";
      $("#multi-country").each(function () {
         var $this = $(this);   
         if(selText !=""){
          selText = selText.concat(","); 
          selText = selText.concat($this.text());
         }
         else
            selText=$this.text();
      });
      //alert(selText);
      document.getElementById("selected_values").value=selText;
    });

    </script>


    </body>
    </html>

I want these selected values to be displayed in the field below.

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());
  });
});
