Jquery stopPropagation не работает с флажком

0 голосов
/ 01 июня 2018

У меня есть флажок в заголовке DataTables, и всякий раз, когда я нажимаю на флажок, столбец также сортируется.Почему-то я не могу остановить распространение события.

Все решения, которые я искал, указывают на использование либо 

event.stopPropagation();

, либо 

return false;

Я не мог заставить это работать хотя.Я попробовал оба решения по отдельности и как комбинацию, но без игры в кости. 

$(document).ready(function() {
  $('#example').DataTable();

  $(document).on("click", ".cb-select-all", function(e) {
    e.stopPropagation();
    // return false;
  });
});
.float-right {
  float: right;
}

.cb-select-all {
  position: absolute;
  right: 15px;
  margin: 0 !important;
}

th {
  position: relative;
}

Я обнаружил, что когда я использую подход return false;, он даже не позволяет мне проверять вход.Что я делаю не так?

Редактировать

Я также пытался использовать другое событие, например change и mouseup, но ни одно из них не работало.

.on метод делегирует событие.

Для получения подробной информации вы можете обратиться к jQuery Event Delegation.

Вкратце, делегированное событие будет выполнено, только если событие уже передано в контейнер.(в вашем случае document).Таким образом, ваш stopPropagation работает, но он уже распространен в документе.

Это можно исправить двумя способами

Если ваш элемент доступен во время выполненияКод использует прямое .click событие вместо .on

Иначе, если ваш элемент является динамически генерируемым элементом, используйте mousedown событие вместо click.(mousedown событие вызывается до события щелчка)

попробуйте изменить 

$(document).on("click", ".cb-select-all", ...

на 

$(".cb-select-all").on("click", ...
...
