Как заставить HTML-таблицу расширяться при клике?

Я рендеринг HTML-таблицы с помощью JavaScript. Я сделал таблицу успешно, но теперь у меня есть одно требование, чтобы показать некоторые новые данные в строке, как по щелчку развернуть строку

Функциональность таблицы:

Я заполняю свой стол. У некоторых брендов в каждом бренде есть несколько предметов, которые я хочу показать, когда на бренд нажимают.
Я почти создал таблицу, но не смог создать расширяемую строку
Мой столбец также заполняет неправильные данные

В своем коде я прокомментировал все строки, что я делаю в какой строке

Проблемы, с которыми я сталкиваюсь

Я уже прокомментировал строку, где я вычисляю netamount для заполнения внутри tbody как мудрый бренд GRN entery но это вызывает проблему

Я создал два фрагмента кода, один из которых представляет собой полностью статический HTML-код, похожий на то, что я хочу, и второй, чтобы показать, что я сделал.

Помощь, которую я нашел в Google

Ответ 2

Я предлагаю вам использовать DataTables.

DataTables предлагает богатый API для рендеринга данных строк, отображения/скрытия столбцов, поиска/фильтрации, подкачки страниц и т.д. Его можно стилизовать с помощью пользовательского интерфейса jQuery или Bootstrap или собственного брендинга. В отличие от написания вашей собственной логики отображения таблиц, библиотеки DataTables бесплатны и чрезвычайно гибки.

Смотрите: https://datatables.net/examples/api/row_details.html.

Ответ 3

Передайте "строку, по которой щелкнули" или "строку, которую мы хотим добавить после строки" в функцию расширения

td.addEventListener('click', function(){
    expand(row);
});

Затем просто разверните новые строки, используя:

function insertAfter(elm, newElm) {
    elm.parentNode.insertBefore(newElm, elm.nextSibling);
}

Пример кода ниже:

function format(number, decimals = 2, locale = 'en-in') {
  const fixed = parseInt(number).toFixed(decimals);
  const [int, dec] = fixed.split('.')
  const intFormatted = (+int).toLocaleString(locale)
  return intFormatted + (dec ? '.' + dec : '');
}

Чтобы достичь ожидаемого результата, используйте нижеприведенную опцию создания новой таблицы внутри кликаемого тд

Нажмите значок плюса, чтобы получить название бренда
Отфильтруйте элементы по данным, используя название бренда
Создание таблицы с элементами для этого бренда
Скрытие строки элементов при выборе другой строки с помощью class-itemsRow
При нажатии на уже выбран, удалить отображение стиля: нет, вместо повторного создания таблицы

Ответ 5

Как реализовать переключение слайдов таблицы...

Вероятно, проще всего поместить обработчик кликов на всю таблицу,.stopPropagation() и проверить, что было нажато.

Если щелкнуть тд в ряду с colspan, закройте в нем букву p. Если это не тд в ряду с colspan, затем закройте, затем переключите следующую строку p.

По сути, это обернуть весь ваш письменный контент в элемент внутри tds, так как вы никогда не захотите сдвинуть вверх td или tr или форма таблицы изменится!

Что-то вроде:

$(function() {

      // Initially hide toggleable content
    $("td[colspan=3]").find("p").hide();

      // Click handler on entire table
    $("table").click(function(event) {

          // No bubbling up
        event.stopPropagation();

        var $target = $(event.target);

          // Open and close the appropriate thing
        if ( $target.closest("td").attr("colspan") > 1 ) {
            $target.slideUp();
        } else {
            $target.closest("tr").next().find("p").slideToggle();
        }                    
    });
});

Попробуйте это с этим примером jsFiddle.

... и попробуйте этот jsFiddle, показывающий реализацию переключателя + - -.

HTML просто должен иметь чередующиеся строки из нескольких тд, а затем строку с тд colspan больше 1. Очевидно, что вы можете легко настроить специфику.

HTML будет выглядеть примерно так:

<table>
    <tr><td><p>Name</p></td><td><p>Age</p></td><td><p>Info</p></td></tr>
    <tr><td colspan="3"><p>Blah blah blah blah blah blah blah.</p>
    </td></tr>

    <tr><td><p>Name</p></td><td><p>Age</p></td><td><p>Info</p></td></tr>
    <tr><td colspan="3"><p>Blah blah blah blah blah blah blah.</p>
    </td></tr>

    <tr><td><p>Name</p></td><td><p>Age</p></td><td><p>Info</p></td></tr>
    <tr><td colspan="3"><p>Blah blah blah blah blah blah blah.</p>
    </td></tr>    
</table>

Ответ 6

Почти чистый пример решения JavaScript, разбивающий части для заголовков на функции, функции для строк подробностей, где он просматривает заголовок, чтобы подвести суммы - я добавил элемент, чтобы продемонстрировать это.

Если вы запустите это, вы можете развернуть верхние заметки, чтобы увидеть подробные заметки о том, что я сделал. (нажмите большую синюю кнопку)
