(function() { var app = { // routes (ie. views and their functionality) defined here 'routes': { 'some-view': { 'rendered': function() { console.log('this view is "some-view"'); } }, 'another-view': { 'rendered': function() { console.log('this view is "another-view"'); app.routeElem.innerHTML = '<p>This javascript content overrides the static content for this view.</p>'; } } }, // The default view is recorded here. A more advanced implementation // might query the DOM to define it on the fly 'default': 'the-default-view', 'routeChange': function() { app.routeID = location.hash.slice(1); app.route = app.routes[app.routeID]; app.routeElem = document.getElementById(app.routeID); if (app.route) { app.route.rendered(); } }, // The function to start the app. 'init': function() { window.addEventListener('hashchange', function() { app.routeChange(); }); // If there's no hash in the URL, change the URL to // include the default view's hash if (!window.location.hash) { window.location.hash = app.default; } else { // Execute routeChange() for the first time app.routeChange(); } } }; window.app = app;
