Hi,


I am working on an examination portal.

The Test page is having Next and Previous buttons. If previous button is clicked, we need to check whether the question is answered or not. If answered, Page expired message should display. Else go back to previous page.

Please help me on this.

推荐答案

使用会话.
如果用户回答该页面，
成功提交后，请对该页面进行会话，然后
在此会议中给予一些价值".
如果用户未回答该页面，则提供会话值= null
和页面加载事件
检查该会话值.如果为null，则必须对其进行解析；如果不为null，则检查您在问题的提交"按钮上提供的值.
如果Equall，则将其转发到您想要的页面.
