//定义Store

var ItemSelectorStore = new Ext.data.ArrayStore({
    fields: [
        { name: ‘BaseInfoId‘ },
        { name: ‘Title‘ }
    ]
});

 var rows = grid.getSelectionModel().getSelections();
                if (rows.length < 1)
                { Ext.MessageBox.alert(‘提示‘, ‘请选择要删除的记录！‘); return; }
                else
                {
                    EditItemSelectorFormWin_Dele.show();
                    Ext.getCmp("EditItemSelectorFormWin_Dele").setTitle("批量删除");
                    ItemSelectorStore.removeAll();

                    for (var i = 0; i < rows.length; i++) {
                        ItemSelectorStore.insert(i, new ItemSelectorStore.recordType({ BaseInfoId: rows[i].get("BaseInfoId"), Title: rows[i].get("Title") }));//插入到最后一行
                    }

                    document.getElementById(‘howMany_Dele‘).innerText = "您将要删除以下" + rows.length + "篇文章";
                }

    for (var i = 0; i < ItemSelectorStore.getCount() ; i++) {
                    var record = ItemSelectorStore.getAt(i);
                    StrBaseInfoId += record.get("BaseInfoId") + ‘,‘;
