Backbone.js - History is creating two entries

Backbone.js - History is creating two entries

I'm not sure how to express this in code, as I can't seem to locate the
problem, but my issue is that Backbone.history seems to be recording two
items when a user clicks on a list item in my app.
This is not consistent.
My app has a 4 item navigation at the bottom that links to 4 main sections
(the first one being home - routed to '/'). If I load up the app, go to
one of the other navigation pages, then click the 'Home' button again and
then click one of the navigation options I get a list of items to choose
from. If I then choose one two entries are added - Firstly, for some
reason, a reference to the home route with /# at the end and then the
route for the item I clicked.
The end result is that 'back' then inexplicably takes me to the home page.
If it helps, my router looks like this...
var siansplanRouter = Backbone.Router.extend({
initialize: function () {
var that = this;
this.routesHit = 0;
//keep count of number of routes handled by your application
Backbone.history.on('route', function() { that.routesHit++; },
this);
window.SiansPlanApp.render();
window.SiansPlanApp.router = this;
},
routes: {
'': 'showHome',
'home': 'showHome',
'hub': 'showHome',
'samples': 'showJqmSamples',
'mealplanner': 'showCurrentMealPlanner',
'mealplanner/:planId': 'showMealPlanner',
'recipes': 'showRecipeSearch',
'recipes/:recipeId': 'showRecipe',
'settings': 'showSettings',
'versioninfo': 'showVersionInfo',
'*other': 'showHome'
},
routesHit: 0,
back: function() {
if(this.routesHit > 1) {
window.history.back();
} else {
//otherwise go to the home page. Use replaceState if
available so
//the navigation doesn't create an extra history entry
this.navigate('/', { trigger: true, replace: true });
}
},
showHome: function () {
SiansPlanApp.renderHome();
},
showJqmSamples: function () {
SiansPlanApp.renderView(new SiansPlanApp.views.Hub.Samples());
},
showMealPlanner: function (planId) {
SiansPlanApp.renderView(new
SiansPlanApp.views.Planner.MealPlanner({ id: planId }));
},
showCurrentMealPlanner: function () {
SiansPlanApp.renderView(new
SiansPlanApp.views.Planner.MealPlanner({ current: true }));
},
showRecipeSearch: function () {
SiansPlanApp.renderView(new SiansPlanApp.views.Recipes.Search());
},
showRecipe: function (recipeId) {
SiansPlanApp.renderView(new
SiansPlanApp.views.Recipes.Recipe({ id: recipeId }));
},
showSettings: function () {
SiansPlanApp.renderView(new
SiansPlanApp.views.System.Settings());
},
showVersionInfo: function () {
SiansPlanApp.renderView(new
SiansPlanApp.views.About.VersionInfo.ListView());
}
});
I've got some basic elements in a kick off file too here...
define(['router', 'regions/r-app', 'jquery', 'domReady'],
function (SiansPlanRouter, AppRegion) {
var run = function () {
// Global click event handler to pass through links to navigate
$(document).on("click", "a:not([data-bypass])", function (e) {
var href = { prop: $(this).prop("href"), attr:
$(this).attr("href") };
var root = location.protocol + "//" + location.host +
SiansPlanApp.root;
if (href.prop && href.prop.slice(0, root.length) === root) {
e.preventDefault();
Backbone.history.navigate(href.attr, true);
}
});
$.ajaxPrefilter(function (options, originalOptions, jqXhr) {
//options.url = '/api' + options.url;
});
// Create the global namespace region object.
window.SiansPlanApp = new AppRegion();
// Adds the authorization header to all of the API requests.
$(document).ajaxSend(function (e, xhr, options) {
xhr.setRequestHeader("Authorization", 'SiansPlan ' +
SiansPlanApp.cookies.getSessionData());
});
// Load up session data if any is present yet - this can't
happen until the XHR headers are set up.
SiansPlanApp.session.loadSession();
// Instantiate the router.
window.SiansPlanApp.router = new SiansPlanRouter();
// Boot up the app:
Backbone.history.start();
};
return {
run: run
};
});
