Given is a form that is followed by a confirmation page where you have to confirm you entered data of previous form. Now if the user refreshes this recapitulation page, the data form the previous form reposts. Is there a way to prevent that in JavaScript?

我知道它不是理想的解决方案，它应该在服务器端发生.但是在这种情况下，我别无选择.

I know its not a ideal solution, it should happen on the server side. But i have no choice in this case.

推荐答案

您不能阻止用户使用javascript重新发布.此操作应在服务器端使用发布后重定向模式完成.

You can't prevent the user from reposting using javascript. This should be done server side using the redirect after post pattern.

一种可能但不可靠的解决方案是使用window.location.href模拟来自javascript的重定向.

A possible but not robust solution is to simulate the redirect from javascript using window.location.href.
