How to redirect to the previously question page in online examination system project?

推荐答案

这个问题有些含糊.但是...

如果您自己创建某件东西，则取决于您如何使用给定的答案来检索上一页.这并不难，因为您知道给定(或尚未给定)的答案以及显示的每个页面(或问题).因此，在显示问题之前，请检查是否已给出答案并进行显示.如果找不到答案，您只需将其留空.这样，您就可以在问题中来回导航，而不必担心这一点，因为它已经在通用解决方案中进行了处理.

祝您好运！

This question is somewhat vague. But...

If you are creating something yourself it is up to you to retrieve the previous page with the given answer. This wouldn''t be that hard because you know the given (or not yet given) answers and for each page (or question) you show. So before you show a question you check if there is already an answer given and show that. When no answer is found you simply leave it empty. That way you can navigate back and forward through the questions without having to worry about this because it is already handled in a generic solution.

Good luck!

保留所有问题的计数器，您可以使用单个页面，并在此页面上显示不同的(适当的)问题.

keep a counter of the number of questions, and you can use a single page, and display different(appropriate) Questions based on that.
