摘要
现有网络考试系统在线考试时需要频繁与服务器交互引起独占式请求,页面重复加载,这些情况不仅让考生处于不连续的考试状态中,同时也消耗大量服务器资源.AJAX技术的在线考试系统设计模型,实现异步式随机抽题,自动保存数据,自动提示信息,提供更为人性化,更具交互性与响应性的在线考试体验.
Such problems as monopolizing request, page reloading resulting from the frequent interchange between the current online test system and the server, subject the tester to a non-consistent test experience and at the same time cause a great deal of server resource waste; while the new design mold of online test system based on the AJAX technology helps to get seperate test questions randomly, saves and protects data automatically, and prompts information automatically, bringing the users better online test experience with more user-friendly, interchanged and interacting operation.
