Datatable button expand/collapse row JQuery

I am using jQuery Datatable and I want to add a button for expand/collapse all row of my table. But I have an issue for the expand when I have row already expanded, and I click on the Button expandALL the row that I expand first is collapsed now and the other expand .. Or if I do the inverse he will be expanded and the other collapse .. How can I do for expand all row even I have already one expand (same case with the collapse)

    function init() {
      Docu.table = $('.js-table-doc').DataTable(dataTableSettngs());
      $('#btn-show-all-doc').on('click', expandCollapseAll);
    }

function dataTableSettings() {
            return {
                responsive: {
                    details: {
                      type: 'column'
                    }
                },
                serverSide: true,
                searching: false,
                columnDefs: [
                             {targets: [0, 8], orderable: false}}
                  ], 
                 columns: [{data: 'id'},
                          {data: 'name'}]
          }

function expandCollapseAll() {
        Document.table.rows(':not(.parent)').nodes().to$().find('td:first-child').trigger('click').length ||
        Document.table.rows('.parent').nodes().to$().find('td:first-child').trigger('click')

        }

Solution

  • Your code has only open action. To close

    table.rows('.parent').nodes().to$().find('td:first-child').trigger('click')

    https://www.gyrocode.com/articles/jquery-datatables-how-to-expand-collapse-all-child-rows/#responsive

    var table = $('#example').DataTable({
  responsive: {
    details: {
      type: 'column'
    }
  },
  columnDefs: [{
    className: 'control',
    orderable: false,
    targets: 0
  }],
  order: [1, 'asc']
});

$('#btn-show-all-doc').on('click', expandCollapseAll);

function expandCollapseAll() {
  table.rows('.parent').nodes().to$().find('td:first-child').trigger('click').length || 
  table.rows(':not(.parent)').nodes().to$().find('td:first-child').trigger('click')
}
