摘要
针对B/S架构在线考试系统中因各种突发事件导致答案未正常提交的情况,在分析已有的解决方案的基础上,提出一种基于Ajax(Asynchronous JavaScript and XML)的在线考场保护/恢复机制。该机制使浏览器端与服务器端进行实时交互,从而达到考场保护,进而将考场恢复至异常发生前状态的目的。
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.
