как изменить атрибут проверки ввода

пока я нажимаю username1 в dropdown, переключатель sepc view на правой карточке будет отключен. Но код не работает. html-код:

<div class="container">
  <div class="row row-cols-2">
    <div class="col">
      <div class="card">
        <div class="card-body">
          <div class="dropdown">

            <button class="btn btn-secondary dropdown-toggle" type="button" id="dropdownMenuButton" data-toggle="dropdown"  aria-haspopup="true" aria-expanded="false">
              Dropdown button
            </button>
            
            <div class="dropdown-menu" aria-labelledby="dropdownMenuButton">
              <a class="dropdown-item" href="#" id="username1">Username1</a>
              <a class="dropdown-item" href="#" id="username2">Username2</a>

      </div>
    </div>

  </div>
</div>

js-код:

$(document).ready(function(){
  $("#username1").click(function(){
  var elmnt = document.getElementById("specview");
  var attr = elmnt.getAttributeNode("checked");
  elmnt.removeAttributeNode(attr);
     
  });
});

Переключатель Bootstrap, который я использую:https://www.bootstraptoggle.com/ Ссылка на мой проект:https://codepen.io/nutkin/pen/KKgJNMd

Checked — это свойство, установите для него значение false elmnt.checked = false;   -  person epascarello    schedule 19.01.2021

Вы смешали javascript с jquery. На самом деле вам нужно использовать класс переключения, чтобы включить выключение примера проекта здесь https://codepen.io/exclutips/pen/qBavRWM

$(document).ready(function(){
  $("#username1").click(function(){
    $('#specview').parent('.toggle').toggleClass('on off');
    $('#specview').removeAttr('checked');
  });
});


$(document).ready(function(){
  $("#username1").click(function(){
    $('#specview').parent('.toggle').toggleClass('on off');
    $('#specview').removeAttr('checked');
  });
});

Согласно документации:

$('#toggle-demo').bootstrapToggle('on') // Sets the toggle to 'On' state

Следовательно, вам нужно изменить обработчик события click на:

$("#username1").on('click', function(e) {
    $('#specview').bootstrapToggle('on');
});

Фрагмент:

$("#username1").on('click', function(e) {
    $('#specview').bootstrapToggle('on');
});

Пожалуйста, выполните следующий пример кода:

Проверить

document.getElementById("checkbox").checked = true;

Снять галочку

document.getElementById("checkbox").checked = false;
