<!DOCTYPE html>
<head>
<title>View Example</title>
<script src="https://code.jquery.com/jquery-2.1.3.min.js" type="text/javascript"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/underscore.js/1.8.2/underscore-min.js" type="text/javascript"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/backbone.js/1.1.2/backbone-min.js" type="text/javascript"></script>
</head>
<body>
<script type="text/javascript">
//'ViewDemo' is a name of the view class
var ViewDemo = Backbone.View.extend({
//This function is called when the view is instantiated
initialize:function(){
document.write('Welcome to yiibai.com!!!');
}
});
//'myview' is an instance of the view 'ViewDemo'
var myview = new ViewDemo();
</script>
</body>
</html>
