PrevenDefault(); alternative when using data-route?

[ch...@hiplogiq.com]

Hello All,

When a user makes a change to a page and then tries to navigate away from the page I need to cancel the redirect and display some warnings. Since using data-route already prevents the DOM default, is there a way that I can do the same thing when using data-route to an anchor tag?

Any help is much appreciated,

Chase

Basically, I need to cancel the redirect.

I don't know of a built-in way. No joke, one time I had to do this, so I overrode (sp?) `Batman.redirect`  inside a Batman.View, something like this:

class MyApp.WhateverView extends Batman.View
  viewWillAppear: ->
    @oldBatmanRedirect = Batman.redirect
    Batman.redirect = =>
      if confirm("Are you sure?")
        @oldBatmanRedirect.apply(null, arguments)

  viewWillDisappear: ->
    Batman.redirect = @oldBatmanRedirect
 

(data-route delegates to Batman.redirect: https://github.com/batmanjs/batman/blob/master/modules/view_layer/bindings/route_binding.coffee#L32)

hope that helps,

robert
