How to pass data from one page to another?

Question

I'm using Framework7 on my website. I'm working on a register form with 5 register stages (pages). When I navigate from one page to another I do the following, for example:

app.views.main.router.navigate('/registerB/', { context: { email: fEmail} });

In the next page (in this case, registerB), how can I access the data (email) ?

Thanks in advance.
