srcmini本文概述
Backbone.js事件stopListening方法：
句法：
object.stopListening(other, event, callback)参数说明
其他：用于定义另一个对象的名称。
事件：用于绑定对象。
回调：它是对代码的引用，并以对象作为上下文进行调用。
让我们举个例子。
请参阅以下示例：

//Create an object 'myVal' and 'myVal1' and extend them using Backbone.Events method
var myVal = _.extend({name:'Hello..'}, Backbone.Events);
var myVal1 = _.extend({name:'Welcome to srcmini'}, Backbone.Events);
//created the 'listenMe' callback function and invoked when one object listens to particular event on another object
var listenMe = function(){
document.write("The value is: ");
document.write(this.name);
};
//The object 'myVal1' listens once for the 'listenMe' event triggered on object 'myVal'
myVal1.listenTo(myVal, 'listenMe', listenMe);
//The 'myVal' has no 'listenMe' event and display the value of 'myVal1'
myVal.trigger('listenMe');
//The 'myVal1' stops listening to specific event on 'myVal' and displays nothing
myVal1.stopListening(myVal, 'listenMe');
myVal.trigger('listenMe');
