| Abstract: | To deal with the accident which induces the answer being not reserved properly during online examinations,a method of examination scene protection/recovery based on Ajax(Asynchronous JavaScript and XML)was proposed.This method makes it possible for a browser real-time interacting with a server,so that the answer could be reserved automatically and then recovered from an accident. |
