更改值上的切换按钮

Question

我正在尝试通过更改切换按钮获取值Y和N，但是无论使用下面的代码，我一直都在获取“ Y”。请帮助

        var lang_dis_button = document.querySelector('.lang-disable');
        var lang_disable = new Switchery(lang_dis_button, { color: '#ED5565' });

        var changeStatus = document.querySelector('.lang-disable')
          , changeField = document.querySelector('#disabled_status');

        changeStatus.onchange = function() {
          if (changeStatus.checked) {
            changeField.innerHTML = 'Disabled';
          } else {
            changeField.innerHTML = 'Active';
          }
        };

     <input type="checkbox" class="lang-disable" name="disabled" id="disabled" value="Y" 
         <?php IF ($disabled == 'Y') { ?> checked><label id="disabled_status">Disabled</label><?php } 
           else { ?><label id="disabled_status">Active<?php } ?></label>
