Добавление настраиваемого раскрывающегося списка в jQuery Datatable нарушило действие сортировки

0 голосов
/ 09 мая 2020

Я пытаюсь добавить настраиваемый выпадающий поиск в jQuery datatable. И эта скрипка - это то, чего я добился до сих пор. Я могу фильтровать столбец при изменении раскрывающегося списка.

Теперь я почти достиг 90% своей цели. Но эта ошибка не дает мне достичь 100%. Эта реализация заставила кнопки сортировки переместиться ниже в поле поиска. И всякий раз, когда я нажимаю на поле поиска, оно сначала сортирует соответствующий столбец.

enter image description here

Это мой код: 

/* Custom filtering function which will search data in column four between two values */
$.fn.dataTable.ext.search.push(
    function( settings, data, dataIndex ) {
        var max = parseInt($('#cars').children("option:selected").val(), 10 );
        var age = parseFloat( data[3] ) || 0; // use data for the age column

        if (isNaN( max ) || age <= max )
        {
            return true;
        }
        return false;
    }
);

$(document).ready(function() {
        $('#example thead th').each( function () {
        var title = $(this).text();
        $(this).html( '<input type="text" placeholder="Search '+title+'" />' );
    } );

    var table = $('#example').DataTable();

    table.columns().every( function () {
        var that = this;

        $( 'input', this.header() ).on( 'keyup change', function () {
            if ( that.search() !== this.value ) {
                that
                    .search( this.value )
                    .draw();
            }
        } );
    } );

    table.column(3).every( function () {

        var column = this;
        var select = $('<select id="cars"><option value=""></option><option value="20">20</option><option value="30">30</option><option value="40">40</option><option value="50">50</option></select>')
          .appendTo($(column.header()).empty())

    });

    // Event listener to the two range filtering inputs to redraw on input
    $('#cars').change( function() {
        table.draw();
    } );
} );

Пожалуйста, сообщите мне, как мне удалить параметр сортировки из строки окна поиска и переместить параметр сортировки обратно в строку заголовка таблицы. Спасибо.

Вот версия вашего кода с некоторыми изменениями.

Конечным результатом является таблица, которая выглядит следующим образом:

Указывает на заметку:

1) Я использую fixedHeader.dataTables.min.css выше - это осталось от еще одна демонстрация - я не думаю, что она действительно актуальна для вас - вы, вероятно, можете удалить ее.

2) Существует жесткое кодирование для «больше / меньше 50» logi c. Я уверен, что есть способы улучшить это, но для этой демонстрации я надеюсь, что все в порядке.

3) Я удалил большую часть тестовых данных HTML, чтобы список кода был коротким.

Вы можете просто остановить скрипт для сортировки по stopPropagation.

Просто поместите этот код в свой скрипт: 

  $('input').click(function(e) {


      e.stopPropagation();

  });
