在数据表中进行筛选时更新总和

Question

我需要你的帮助，我正在使用数据表，我已经设法对我的两列（ACOUNT 和 TOTAL）求和，但是当我按用户进行筛选时，我希望更新和仅显示该用户的汇总数据。对于这个项目，我使用数据表中的库 Sum() 和 Bootstrap 样式。

$(document).ready(function(){
          var table = $('#table_id').DataTable({
            processing: true,
            ordering: true,
            "pageLength": 50,
            "lengthMenu": [[5,10,50,-1], [5,10,50,"All"]],
            "order": [[ 1, "asc" ]],
            "autoWidth": false,
            "language":{
              "url": "//cdn.datatables.net/plug-ins/1.10.21/i18n/Spanish.json"
            }
          });

          //SUMA
          //ACOUNT
          var arrSalePriceOne = table.column(1).data().sum();
          $("#tblProfit").text((+arrSalePriceOne).toLocaleString('en-US'));
          //TOTAL
          var arrSalePriceTwo = table.column(2).data().sum();
          $("#sumados").text((+arrSalePriceTwo).toLocaleString('en-US'));

          // dropdown
          $('.filter-select').change(function(){
          table.column($(this).data('column'))
          .search($(this).val())
          .draw();
          });
        });

您可以使用 DataTables {search:'applied'} selector modifier 来确保您只对过滤后的列值求和。

这是一个修改后的下拉更改事件，显示了这一点：

// dropdown
$('.filter-select').change(function(){
  table.column($(this).data('column'))
  .search($(this).val())
  .draw();
            
  var account = table.columns( 1, {search:'applied'} ).data().sum();
  $("#tblProfit").text((+account).toLocaleString('en-US'));
            
  var total = table.columns( 2, {search:'applied'} ).data().sum();
  $("#sumados").text((+total).toLocaleString('en-US'));
            
});

更新：这是一个可运行的片段。它在 table 首次显示时显示总计（无过滤）：

        $(document).ready(function(){
          var table = $('#table_id').DataTable({
            processing: true,
            ordering: true,
            "pageLength": 50,
            "lengthMenu": [[5,10,50,-1], [5,10,50,"All"]],
            "order": [[ 1, "asc" ]],
            "autoWidth": false,
            "language":{
              "url": "https://cdn.datatables.net/plug-ins/1.10.21/i18n/Spanish.json"
            }
          });

          //SUMA
          //ACOUNT
          var arrSalePriceOne = table.column(1).data().sum();
          $("#tblProfit").text((+arrSalePriceOne).toLocaleString('en-US'));
          //TOTAL
          var arrSalePriceTwo = table.column(2).data().sum();
          $("#sumados").text((+arrSalePriceTwo).toLocaleString('en-US'));

          // dropdown
          $('.filter-select').change(function(){
            table.column($(this).data('column'))
            .search($(this).val())
            .draw();
            
            var account = table.columns( 1, {search:'applied'} ).data().sum();
            $("#tblProfit").text((+account).toLocaleString('en-US'));
            
            var total = table.columns( 2, {search:'applied'} ).data().sum();
            $("#sumados").text((+total).toLocaleString('en-US'));
            
          });
          
        });
