javascript - backbone routes – detecting browser back button press

Question

I am trying to find a way to detect when the user has pressed the back / forward button in their browser.

I am using backbone to handle routes, along with backbone to render my views.

The issue is I can not hook into this page change event from anywhere.

I tried putting a log in my initialize function for my views .. but it is not tripped when i use the back button.

I am really not sure how else to detect this page change.

You can bind a callback to Backbone route event:

    Backbone.history.on('route', function () {
        // Do your stuff here
    });

You can use Backbone.history.getFragment() to know were you are standing.
