如下，怎么改才行呀。
/*把GridPanel_win选中的数据插入到GRID中，并用另一个Form1中的数据来更新它*/
var addRecord_update = function (form, grid) {
if (!form.getForm().isValid()) {
Ext.net.Notification.show({
iconCls: "icon-exclamation",
html: "波浪线地方不能为空",
title: "错误"
}); return false;
}
/* grid.insertRecord(0, form.getForm().getFieldValues(false, "dataIndex"));*/
var store1 = GridPanel1.getStore();
var store2 = GridPanel_win.getStore();
var sm = GridPanel_win.getSelectionModel();
var records = sm.getSelections();
store1.insert(0, records);
GridPanel1.getSelectionModel().selectRow(0);
form.getForm().updateRecord(form.record);
