Backbone.js and jQueryMobile routing without hack or other router

Question

I am using backbone.js (0.5.3) with JQueryMobile (1.0 beta 2). I know there are routing conflicts when using those libraries together, and I would like to know if there is a

Answer 1

With jquery 1.2.0, disable ajax and linkBinding

$(document).bind("mobileinit", function(){
    $.mobile.ajaxEnabled = false;
    $.mobile.hashListeningEnabled = false;
    $.mobile.linkBindingEnabled = false;
    $.mobile.pushStateEnabled = false;
  });

after, which with normal Backbone routes, you can link a #id with

<a href="#id" onclick="window.app_router.navigate('new', true)">Report</a>

Answer 2

This may be a bit of a longshot as I have no way to test it, but try extending Backbone's history, and have it listen for a creation event before actually firing off the code. So..

MyHistory = Backbone.History.extend({
    loadUrl : function(fragmentOverride) {
      var fragment = this.fragment = this.getFragment(fragmentOverride);
      var matched = _.any(this.handlers, function(handler) {
        if (handler.route.test(fragment)) {
          //This is the only change from core code.. 
          //We're just wrapping it into a callback.
          $('.ui-page-active').one('pagecreate', function () {
              handler.callback(fragment);
          });
          return true;
        }
      });
      return matched;
    }
});
MyHistory.start();

That might do it, or at least get you on the right path I hope.

Ok the solution is to disable jQuery Mobile ajax loading feature and call the $.mobile.changePage method manually.

HTML page :

    <script type="text/javascript" charset="utf-8" src="js/mobile/jquery.js"></script>
    <script type="text/javascript">
      $(document).bind("mobileinit", function(){
        $.mobile.ajaxEnabled = false;
        $.mobile.hashListeningEnabled = false;
      });
    </script>
    <script type="text/javascript" charset="utf-8" src="js/mobile/jquery-mobile.js"></script>

Then whenever a new route is triggered, I first build my new "jQuery page canvas" in the Backbone View constructor, append it to the HTML document body and set my el view element to this new div :

Backbone.View

    $("body").prepend("""
      <div id="my-id" data-role="page" class="cloudy-background-mobile">
        <div class="cloudy-header" data-role="header" data-position="fixed"></div>
        <div class="cloudy-content" data-role="content"></div>
      </div>
    """)
    this.el = $("#logs-view")

And in the render method :

// Build the content using undescore.js templating system
this.el.find('.cloudy-content').html(this.template({logs : this.collection}));
this.find('.cloudy-header').html(this.template_header({logbook: this.logbook}));

// Change the page using jquery mobile and reapply jquery styles
$.mobile.changePage(this.el, "slide", false, false);
this.trigger( "pagecreate" );

Works like a charm and without any unnecessary hacks :)

Here is my full Backbone View if it can help anyone :

class LogsView extends Backbone.View
  constructor: (options) ->
    super
    $("body").prepend("""
      <div id="logs-view" data-role="page" class="cloudy-background-mobile">
        <div class="cloudy-header" data-role="header" data-position="fixed"></div>
        <div class="cloudy-content" data-role="content"></div>
      </div>
    """)
    @el = $("#logs-view")
    @logbook = options.logbook
    @collection.bind 'reset', @render

    @template = _.template('''
      <ul data-role="listview" data-theme="c" data-inset="true">
        <% logs.each(function(log){ %>
          <li>
            <a href="#logs-<%= log.cid %>"><%= log.getLabel() %></a>
          </li>
        <% }); %>
      </ul>
    ''')

    @template_header = _.template('''
      <h1>Carnets <%= logbook.get('name') %></h1>
      <a href="#logbook-<%= logbook.cid %>-logs-new" data-icon="plus" class="ui-btn-right">&nbsp;</a>
    ''')

  render: =>
    # Build the content using undescore.js templating system
    @el.find('.cloudy-content').html(@template({logs : @collection}))
    @el.find('.cloudy-header').html(@template_header({logbook: @logbook}))

    # Change the page using jquery mobile and reapply jquery styles
    $.mobile.changePage(@el, "slide", false, false)
    @el.trigger( "pagecreate" )
