FAQ - Accordion Expand / Collapse Function - PullRequest
0 голосов
/ 03 мая 2019

Работа над существующей страницей аккордеона "FAQ / Развернуть / Свернуть" и поиск правильной работы функции "Развернуть / Свернуть".

Мне удалось заставить страницу начинаться с того, что все рухнуло, но когда я щелкаю по любому столбцу, чтобы развернуть его, а затем щелкаю по другому, исходный не разрушается.

Важно отметить, что я бы хотел сохранить функцию поиска без изменений.

$('.collapse').collapse(); // Collapse all

// This section makes the search work.
(function() {
  var searchTerm, panelContainerId;
  $('#accordion_search_bar').on('change keyup', function() {
    searchTerm = $(this).val();
    $('#accordion > .panel').each(function() {
      panelContainerId = '#' + $(this).attr('id');

      // Makes search to be case insesitive 
      $.extend($.expr[':'], {
        'contains': function(elem, i, match, array) {
          return (elem.textContent || elem.innerText || '').toLowerCase()
            .indexOf((match[3] || "").toLowerCase()) >= 0;
        }
      });

      // END Makes search to be case insesitive

      // Show and Hide Triggers
      $(panelContainerId + ':not(:contains(' + searchTerm + '))').hide(); //Hide the rows that done contain the search query.
      $(panelContainerId + ':contains(' + searchTerm + ')').show(); //Show the rows that do!

    });
  });
}());

												<p>The lion (Panthera leo) is one of the big cats in the genus Panthera and a member of the family Felidae. The commonly used term African lion collectively denotes the several subspecies in Africa. With some males exceeding 250 kg (550 lb) in weight, it is the second-largest living cat after the tiger. Wild lions currently exist in sub-Saharan Africa and in India (where an endangered remnant population resides in Gir Forest National Park). In ancient historic times, their range was in most of Africa, including North Africa, and across Eurasia from Greece and southeastern Europe to India. In the late Pleistocene, about 10,000 years ago, the lion was the most widespread large land mammal after humans: Panthera leo spelaea lived in northern and western Europe and Panthera leo atrox lived in the Americas from the Yukon to Peru.</p>

												<p>The meerkat or suricate (Suricata suricatta) is a small carnivoran belonging to the mongoose family (Herpestidae). It is the only member of the genus Suricata. Meerkats live in all parts of the Kalahari Desert in Botswana, in much of the Namib Desert in Namibia and southwestern Angola, and in South Africa. A group of meerkats is called a "mob", "gang" or "clan". A meerkat clan often contains about 20 meerkats, but some super-families have 50 or more members. In captivity, meerkats have an average life span of 12–14 years, and about half this in the wild.</p>

Все элементы вначале свернуты, и в основном, когда пользователь нажимает на первую лапу, чтобы развернуться, а затем нажимает на другую лапу, первая лапа должна «свернуться». Когда пользователь нажимает на другую лапу, чтобы развернуться, предыдущая развернутая лапа должна свернуться, так что за один раз может быть развернут только один элемент.

Если вы хотите, чтобы панели вначале были свернуты, не используйте in класс .

Вызов $('.collapse').collapse(); не разрушает ваши панели, он повторно активирует .collapse элементы с параметрами по умолчанию , переопределяя .in (поэтому панели закрыты) и data-parent (так что вы теряете поведение одной панели за раз).

Вам также не нужно определять псевдоселектор :contains три раза при каждом нажатии клавиши. Один раз достаточно. И вам не нужно явно зацикливаться на всех #accordion .panel s, просто используйте достаточно широкий селектор.

// Not necessary.
// $('.collapse').collapse();

// This section makes the search work.
(function() {
  // Makes search to be case insesitive 
  $.extend($.expr[':'], {
    'contains': function(elem, i, match, array) {
      return (elem.textContent || elem.innerText || '').toLowerCase()
        .indexOf((match[3] || "").toLowerCase()) >= 0;
    }
  });

  // END Makes search to be case insesitive

  $('#accordion_search_bar').on('change keyup', function() {
    var searchTerm = $(this).val();
    $('#accordion > .panel').hide(); // Hide all rows.
    $('#accordion > .panel:contains(' + searchTerm + ')').show(); // Show the rows that match the search query.
  });
