If you have instantiated a Router in your application, the following line returns the current fragment:
Backbone.history.getFragment();
From the Backbone.js documentation:
”
[…]
History serves as a global router (per frame) to handle hashchange events or pushState, match the appropriate route, and trigger callbacks. You shouldn’t ever have to create one of these yourself — you should use the reference to Backbone.history that will be created for you automatically if you make use of Routers with routes.
[…]”
If you need the name of the function bound to that fragment, you can make something like this inside the scope of your Router:
alert( this.routes[Backbone.history.getFragment()] );
Or like this from outside your router:
alert( myRouter.routes[Backbone.history.getFragment()] );
