从页面重定向之前询问确认

Question

I have application. Client side is - knockout.

so I have page with form, and i want to ask user confirametion before he will try go to another page (in case if he changed something (this pard is ready))

So routing on all website - its Sammy.js.

I tried : Sammy JS - before

function ViewModel()
{
  Sammy.before(/.*/, function () {

        if (window.confirm('Really go to another page?')){

        }
        else{
            //DO NOTHING AND STAY IN THE SAME PAGE
            //OR SOMETHING ELSE THAT YOU WANT

            return false;
        }

     });
}

its work , but its still working for all website - and its bad. I'm not found way to disable it, so maybe I can do it without sammy???

Thank you guys!

Update: This website is SPA

You can use before , but you must specify options to show the confirmation dialog only when necessary. See the docs . You're specifying to run it for all the routes, you must specify in which routes you want it executed. Before option only gives you information on the next route. If it depends on the current route, you can get it examining the current url:

function extractSammyUrlFrom (context)
{
  // get the hash fragment (curernt route)
  "#" + context.path.split("#")[1] ;
}

If it depends on any other thing in your page, just check it before showing the dialog.
