隐藏 select2 多搜索框

Question

如果 HTML 下拉列表中的值与某个值匹配，我试图使 select2 搜索框可见。以下是我的代码片段。不知何故，始终显示 Select2 下拉列表。感谢任何帮助...

我根据 select2 github 回购的建议添加了 CSS https://github.com/select2/select2/issues/861

<html>
<style type="text/css">
.other {
    display: none !important;
}
</style>

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/select2/4.0.3/js/select2.min.js"></script>
<link href="https://cdnjs.cloudflare.com/ajax/libs/select2/4.0.3/css/select2.min.css" rel="stylesheet"/>

          <select class="one" name="one" id="one">
            <option value="1">1</option>
            <option value="2">3</option>
            <option value="3">3</option>
            <option value="4">4</option>
            <option value="5">5</option>
            <option value="6">6</option>
            <option value="7">7</option>
            
         </select>
         <br>
  
<br>


    <select class="other" name="other" multiple="multiple">
  <option value="AL">Sample1</option>
  <option value="WY">Sample2</option>
    </select>
<script>
   // In your Javascript (external .js resource or <script> tag)
  

  $("#one").change(function() {

  $('#value').change(function()
  {
    if($('#value').val() == '1')
    {
        $('.other').hide();
    } else 
    {
        $('.other').show();
    }
}
)});
  $(document).ready(function() {
      $(".other").select2({
          tags: true
      });
  });
  
    
    </script>
  </html>

Answer 1

$("#one").change(function() {

    console.log('me called');

    if($('#one').val() == '1')
    {
        $('.select2').hide();
        console.log($('#other'))
        console.log('me called1');
    } else 
    {
        $('.select2').show();
        console.log('me called2');
    }
});

这对你有用吗？当您 select 3 然后 select 1 时，select2 元素消失。

Answer 2

你能做这样的事情吗？不确定您的用户案例。但我会建议销毁 select 然后隐藏。稍后再次创建实例并显示。

$("#one").change(function() {

    if($(this).val() == '3')
    {
        $('.other').select2('destroy');
      $('.other').hide();
    } else {
        $(".other").select2({
          tags: true
      });
        $('.other').show();
    }
});
  $(document).ready(function() {
      $(".other").select2({
          tags: true
      });
  });

            <option value="4">4</option>
