用法：

var grid = $("#jqGrid");
var cellvalue =grid .jqGrid("getEditingCellValue", grid [0], rowId, iRow, iCol);

自定义方法：

$.jgrid.extend({
            getEditingCellValue: function (grid, rowId, iRow, iCol) {
                var $t = grid, fr,
                    errors = $.jgrid.getRegional(grid, 'errors'),
                    edit = $.jgrid.getRegional(grid, 'edit');
                if (fr !== null) {
                    var cc = $("td:eq(" + iCol + ")", $t.rows[iRow]), v, v2,
                        cm = $t.p.colModel[iCol], nm = cm.name, nmjq = $.jgrid.jqID(nm),
                        p = $(cc).offset();
                    switch (cm.edittype) {
                        case "select":
                            if (!cm.editoptions.multiple) {
                                v = $("#" + rowId + "_" + nmjq + " option:selected", $t.rows[iRow]).val();
                                v2 = $("#" + rowId + "_" + nmjq + " option:selected", $t.rows[iRow]).text();
                            } else {
                                var sel = $("#" + rowId + "_" + nmjq, $t.rows[iRow]), selectedText = [];
                                v = $(sel).val();
                                if (v) { v.join(","); } else { v = ""; }
                                $("option:selected", sel).each(
                                    function (i, selected) {
                                        selectedText[i] = $(selected).text();
                                    }
                                );
                                v2 = selectedText.join(",");
                            }
                            if (cm.formatter) { v2 = v; }
