death of the hashbang

gistfile1.coffee

# First, we should prevent the Hashbang from ever occuring by 
# overriding Backbone’s ‘loadUrl’ method (Hat tip to Michael Franzkowiak):

Backbone.History.prototype.loadUrl = (fragmentOverride) ->
  fragment = this.fragment = this.getFragment(fragmentOverride, 
                                              this._wantsPushState &&
                                              !this._wantsHashChange)
  matched = _.any this.handlers, (handler) ->
    if handler.route.test(fragment)
      handler.callback(fragment)
      return true
  matched


# Then we need to find a way to make 
# certain links pushstate capable.

  $(document).delegate "a.pushState", "click", (evt) ->
    # Get the anchor href and protocol
    href = $(this).attr("href")
    protocol = this.protocol + "//"

    # Ensure the protocol is not part of URL, meaning its relative.
    # Stop the event bubbling to ensure the link will not cause a page refresh.
    if href.substring(0, protocol.length) != protocol

      # Leading /'s break Backbone router nav
      if href.charAt(0) == '/'
        href = href.substr(1, href.length)
      if Backbone.history._hasPushState
        evt.preventDefault()
        app.router.navigate href, trigger: true
      else
        #Do Nothing
