I'm in charge of the development of a web application.
I did a lot of research and I finally decided to develop this webapp with Backbone and jQuery Mobile. As you certainly know, there are some routing conflicts between jQuery Mobile and BackBone. I decided to use Backbone routing so I disabled jQM routing thanks to this tutorial : http://coenraets.org/blog/2012/03/using-backbone-js-with-jquery-mobile/.
I started to build a sample application (without jQM) with only 3 views and a router. It works perfectly. You can run this application here. I voluntary put jQuery Mobile HTML tags for the next part.
Now, I would like to do the same thing with jQuery Mobile : keep the same header for all templates. The previous tutorial really helped me but I'm still confused about the DOM system of jQM.
What I've tried is here :
index.html (pastebin.com/PcHDaZ2P)
<head>
<title></title>
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="stylesheet" href="css/jquery.mobile-1.0.1.min.css"/>
<!-- The Templates -->
<script type="text/template" id="home">
<p>This is Home page.</p>
<ul data-role="listview" data-inset="true">
<li><a href="#page1">Page 1</a></li>
<li><a href="#page2">Page 2</a></li>
</ul>
</script>
<script type="text/template" id="page1">
<p>This is Page 1.</p>
<ul data-role="listview" data-inset="true">
<li><a href="#">Home</a></li>
<li><a href="#page2">Page 2</a></li>
</ul>
</script>
<script type="text/template" id="page2">
<p>This is Page 2.</p>
<ul data-role="listview" data-inset="true">
<li><a href="#">Home</a></li>
<li><a href="#page1">Page 1</a></li>
</ul>
</script>
<!-- The Scripts -->
<script src="lib/jquery-1.7.1.min.js"></script>
<script src="js/jqm-config.js"></script>
<script src="lib/jquery.mobile-1.0.1.min.js"></script>
<script src="lib/underscore-min.js"></script>
<script src="lib/backbone-min.js"></script>
<script src="js/main.js"></script>
</head>
<body>
<!-- The fixed header -->
<div data-role="header">
<a href="#" data-icon="home">Home</a>
<h1>Header</h1>
</div>
<!-- THE CONTENT FOR THE TEMPLATES -->
<div data-role="content" id="app-content">
</div>
</body>
main.js (pastebin.com/2GXurpby)
window.HomeView = Backbone.View.extend({
template:_.template($('#home').html()),
render:function (eventName) {
$(this.el).html(this.template());
return this;
}
});
window.Page1View = Backbone.View.extend({
template:_.template($('#page1').html()),
render:function (eventName) {
$(this.el).html(this.template());
return this;
}
});
window.Page2View = Backbone.View.extend({
template:_.template($('#page2').html()),
render:function (eventName) {
$(this.el).html(this.template());
return this;
}
});
var AppRouter = Backbone.Router.extend({
routes:{
"":"home",
"page1":"page1",
"page2":"page2"
},
initialize:function () {
// Handle back button throughout the application
$('.back').live('click', function(event) {
window.history.back();
return false;
});
this.firstPage = true;
},
home:function () {
console.log('#home');
this.changePage(new HomeView());
},
page1:function () {
console.log('#page1');
this.changePage(new Page1View());
},
page2:function () {
console.log('#page2');
this.changePage(new Page2View());
},
changePage:function (page) {
console.log($(page.el));
$(page.el).attr('data-role', 'page');
page.render();
$('#app-content').append($(page.el));
var transition = $.mobile.defaultPageTransition;
// We don't want to slide the first page
if (this.firstPage) {
transition = 'none';
this.firstPage = false;
}
$.mobile.changePage($(page.el), {changeHash:false, transition: transition});
}
});
$(document).ready(function () {
console.log('document ready');
app = new AppRouter();
Backbone.history.start();
});
But it doesn't work.
So, can you help me to realize this system : have the same header for all templates and just a variable content in the app-content div with jQuery Mobile ?
Okay, I've finally found the solution by using trigger event.
I just want same header and footer on each page (or template) by using Backbone and jQuery Mobile. This is in fact pretty simple but I was on the wrong way when I researched.
The following is 2 simples applications ; the only difference is here :
The normal app (working jsFiddle : http://jsfiddle.net/QLu4P/)
app.Views.Main = Backbone.View.extend({
initialize : function(params)
{
// ...
},
render : function()
{
// ...
$(this.el).html(renderedContent);
// ...
}
});
The app using jQuery Mobile (working jsFiddle : http://jsfiddle.net/q5TX7/)
app.Views.Main = Backbone.View.extend({
initialize : function(params)
{
// ...
},
render : function()
{
// ...
$(this.el).html(renderedContent).trigger('create');
// ...
}
});
I've just added .trigger('create') on $(this.el).html(renderedContent) !
I've purposely put jQuery Mobile tags on the 2 apps in order to highlight that this is almost the same code.
Hope it gonna be useful.
