已解决状态保存回调：function（settings，data）{ var columns = element.columns（）.visible（）;

var colVisState = $.map(columns, function (col, i) {
                    return col ? true : false;
                });

                data.colVisState = colVisState;
                var portfolioId = "@ViewBag.CurrentPortfolio.Id";

                var columnStatus = data.colVisState;
                $.ajax({
                    type: 'POST',
                    url: '@Url.Action("DataTableVisibilityCustomization", "Portfolio")',
                    data: { ColumnStatus: JSON.stringify(columnStatus), portfolioId: portfolioId },
                    success: function (result) { console.log(result.data); }
                });
            },

这是我的stateSaveCallback函数

stateSaveCallback: function(settings, data) {
  var columns = [];
  $('#' + tableId + ' th').each(function() {
    var index = $(this).index();
    columns.push(settings.aoColumns[index].bVisible ? true : false);
  });
  console.log(columns);
  var portfolioId = "@ViewBag.CurrentPortfolio.Id";

  var columnStatus = columns;
  $.ajax({
    type: 'POST',
    url: '@Url.Action("DataTableVisibilityCustomization", "Portfolio")',
    data: {
      ColumnStatus: JSON.stringify(columnStatus),
      portfolioId: portfolioId
    },
    success: function(result) {
      console.log(result.data);
    }
  });
},
