Question

Page history - back button exists?

I need to have a link in some pages of a website, by clicking on it, it needs to go back to the previous page, just like the browser's back button. What is the right way to do that? I'm thinking that I should use some client side scripting like Javascript, right?

Answer 1

In JavaScript, it's:

history.go(-1);

or

history.back();

Answer 2

Just use

history.go(-1);

But you cannot go forward anymore after that (so the Forward button doesn't bring you back to where you were -- i.e., this is not 100% the same as clicking the Back button).
