<script src="https://cdnjs.cloudflare.com/ajax/libs/backbone.js/1.1.2/backbone-min.js" type="text/javascript"></script>
</head>
<script type="text/javascript">
//'ViewDemo' is a name of the view class
ViewDemo = Backbone.View.extend({
//This function gets called when the view is instantiated
initialize: function(){
document.write("Hello !!!! This is el property...");
}
});
//'viewdemo' is a instance of the 'ViewDemo' class
var viewdemo = new ViewDemo({ el: $("/backbonejs/backbonejs_view.htmlmyapp") });
</script>
<body>
<div id="myapp"></div>
</body>
</html>
