对于给定的事件调用回调函数。
object.trigger(event,[args])
<!DOCTYPE html>
<head>
<title>Event Trigger 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">
//Created an object 'myVal' and extended it using Backbone.Events method
var myVal = _.extend({title:'YiiBai!!!', site:'www.yiibai.com'}, Backbone.Events);
//The on() method will bind the callback function to an object
myVal.on('myFunc', function () {
document.write("The triggered value for site is: ");
document.write(this.site); //value of site will get displayed by referring the current object
});
// The trigger() method triggers the 'myFunc' event on 'myVal'
myVal.trigger('myFunc');
</script>
</body>
</html>
