这么一来在取得 DataGrid 的 Checkbox 有勾选的数据值就可以沿用方式一的程序，
view sourceprint?
1.$('#ButonGetCheck').click(function(){
2.var checkedItems = $('#dg').datagrid('getChecked');
3.var names = [];
4.$.each(checkedItems, function(index, item){
5.names.push(item.productname);
6.});
7.console.log(names.join(","));
8.});
执行结果：
