Javascript 如何在jQgrid中仅选择筛选的行？

我有一个网格（由jqGrid 4.15.2制成）。代码如下所示：

$.jgrid = $.jgrid || {};
$.jgrid.no_legacy_api = true;
$.jgrid.useJSON = true;

$(function () {
    "use strict";

    var $grid = $("#list"),
        maximizeGrid = function () {
            var newWidth = $grid.closest(".ui-jqgrid").parent().width();
            $grid.jqGrid("setGridWidth", newWidth, true);
        };

    // Resize grid if window is being resized
    $(window).on("resize", maximizeGrid);

    $grid.jqGrid({
        colNames: ["", "Form #", "Form", "Plan", "Class", "Drug"],
        colModel: [
            {name: "act", template: "actions"},
            {
                name: "FormId",
                align: 'center',
                fixed: true,
                frozen: true,
                resizable: false,
                width: 100,
                editable: "hidden"
            },
            {name: "FormName", search: true, stype: "text"},
            {name: "PlanName", search: true, stype: "text"},
            {
                name: "DrugGroupName",
                edittype: "select",
                editable: true,
                search: true,
                editoptions: {
                    dataUrl: "/ajax/drug_groups/get_all",
                    buildSelect: function (data) {
                        var select = "<select>", i;
                        for (i = 0; i < data.length; i++) {
                            select += "<option value='" + String(data[i].Id) + "'>" + $.jgrid.htmlEncode(data[i].DrugGroupName) + "</option>"
                        }

                        return select + "</select>";
                    },
                    selectFilled: function (options) {
                        setTimeout(function () {
                            $(options.elem).select2({
