Don’t leave this page cause I said so dialog

I have a process where I create an object on one screen, and then in the next screen add some information to that object.

Problem is, if you navigate away from that second page I have an object that has no important info attached to it.

My process is a wizard approach to setting up a new account, which only really has a name, and then the account has users and billing info attached to it in separate models/tables. So give it a name and save it, redirect to the next screen and add users and billing.

So I want the “Hey you! Don’t navigate away” dialog to appear on all but a few links and form submits on the add users and billing page. Its actually super easy.

Take a look at this very nicely formated gist I would put this stuff in code tags and display it here but it looks like crap and I can’t embed gists unless I pay wordpress. And wordpress stripped all my erb and html tags so just go look at the gist.
