Routing and responsive layout with Oracle JET


After creating my first pages with Oracle JET, some database data visualization and an Input Form, I want to create a JET application with navigation and a responsive layout.

Here are some pictures how the application looks like after building it:

Main Content Area
Start screen of the application

This is the startscreen of the application:

When “Table” is selected, there is a submenu where a user can make another selection:


When a choice is made in the subselect, you see the results:


If “Chart” is selected you see a chart:


Here are now some screenshots of the application when the browser is shrinked. You see also the “hamburger” icon for a replacement of the menubar.

This is the main page:

Main page

After selecting “Table” and choose the “Department” option, you can see the results are located under the subselect menu: 


When the “Chart” is selected in the menu you see the chart. Oracle JET automatically resize the bar’s of the chart:

Resized charts

The “Chart” menu option without the menu shown:

New charts

Now let’s dive deeper in the code.

<!DOCTYPE html>
<title>Emp Dept Application</title>
<meta charset="UTF-8"/>
<meta name="viewport" content="width=device-width, initial-scale=1"/>
<link rel="icon" href="css/images/favicon.ico" type="image/x-icon"/>
<!-- This is the main css file for the default Alta theme -->
<link rel="stylesheet" href="css/libs/oj/v1.1.2/alta/oj-alta-min.css" type="text/css"/>
<!-- These style classes are for demonstration purposes only. -->
<link rel="stylesheet" href="css/demo-alta-patterns-min.css"/>
<!-- This is where you would add any app specific styling -->
<link rel="stylesheet" href="css/override.css" type="text/css"/>
<!-- RequireJS configuration file -->
<body class="demo-appheader-offcanvas-pushwrapper">

<header id="headerWrapper" role="banner" data-bind="ojModule: { name: 'header'}"></header>


This is the code of index.html. In this code you can see there’s a header and a body (content) element. You can also add a footer element here.
In the header binding you find also a viewName with the name ‘offcanvasheader’. This points to the offcanvasheader.tmpl.html. More explanation about oj-module you can find here.

oj.ModuleBinding.defaults.modelPath = 'modules/';
oj.ModuleBinding.defaults.viewPath = 'text!../templates/';
oj.ModuleBinding.defaults.viewSuffix = '.tmpl.html';
oj.Router.defaults['urlAdapter'] = new oj.Router.urlParamAdapter();
var router = oj.Router.rootInstance;
router.configure( {
'main' : {
label : 'Main', isDefault : true
'table' : {
label : 'Table'
'chart' : {
label : 'Chart'
var viewModel = {
router : router, optionChangeHandler : function (event, data) {
if (data.value == undefined) {
data.value = 'main';
if ('AppHeaderNav' === event.target.id && event.originalEvent) {
$(document).ready(function() {
oj.Router.sync().then(function() {
ko.applyBindings(viewModel, document.getElementById('routing-container'));

This is the code of main.js. In the index.html file there is a reference to this file.

script data-main="js/main"

In this code the router instance is being created. The “AppHeaderNav” in the code points to the element in the code below.


syncs the page with the choice of the user.


</div> <!-- oj-row -->
</div> <!-- oj-col -->
</div> <!-- oj-row -->
</div> <!-- demo-appheader -->
<!-- template for rendering app nav data -->

This is the code of header.tmpl.html
In the ojNavigationList you can find the following code:

selection: $root.router.stateId()

This points to the router in the main.js.

For the “Table” page I used the example which you can find in the cookbook here.
I changed only one thing in table.tmpl.html. That is this:

selection: $root.router.stateId()

For the “Chart” page I also used an example from the cookbook. link.
This is the code (partly) in chart.js:

var viewModel = {
router: undefined,
initialize : function(data) {
if (this.router) {
router = oj.Router.rootInstance;

selectHandler: function(event, ui) {
if ('chart-container' === event.target.id && event.originalEvent) {

return viewModel;

So this is the code for creating a application with a responsive layout and with multiple pages. With the modulair plan you can expand your JET-application very simple. Create an extra page, add the data (for example a REST-service), add the page to the menu and reload.
Also JET supports a responsive layout, it works very easy for different screen sizes. I wonder how Oracle places Oracle JET versus Oracle MAF for mobile devices.
