我这样做的原因不是出于邪恶目的或其他目的.我正在开发一款考试软件.用户回答考试/调查/测验中的所有问题，提交表单，然后转到页面以查看反馈.目前，如果他们按下硬件后退按钮，则会收到警告框，指出数据已经提交，但是仍然可以点击OK并返回考试并重新提交，因此重新提交相同的结果或更改他们的答案并重新提交，

My reasons for this aren't for nefarious purposes or anything. I'm working on a piece of exam software. A user answers all the questions in an exam/survey/quiz, submits the form, and is then taken to a page to see the feedback.

我已经研究过HTML5历史记录功能，但是由于在较新版本的Android中缺乏支持，因此无法使用它.我需要可以在Android，iPhone以及WP7上正常运行的功能.

I've already looked into the HTML5 History capabilities, but because of it's lack of support in newer versions of Android, I can't use it. I need something that will work across Android, iPhone, and preferably WP7.
