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

} else {

}
if (cm.formatter) { v2 = v; }
break;
