Answer 1

如果要保存更改，则可以要求商店使用.sync（）与服务器同步或放弃它们，然后使用.reload（）重新加载

Answer 2

您可以调用commitChanges来保存您的修改，而调用rejectChanges来重置它们。

Answer 3

To 'reject' all your changes in record you can use(ExtJS 3.x):

record.reject();

Here your all changes will be rejected which you made from creation of record or last commit of record.
