1, 利用作用域的继承方式

由于作用域的继承是基于js的原型继承方式，所以这里分为两种情况，当作用域上面的值为基本类型的时候，修改父作用域上面的值会 影响到子作用域，反之，修改子作用域只会影响子作用域的值，不会影响父作用域上面的值；如果需要父作用域与子作用域共享一个值 的话，就需要用到后面一种，即作用域上的值为对象，任何一方的修改都能影响另一方，这是因为在js中对象都是引用类型。

基本类型

2, 基于事件的方式

在一般情况下基于继承的方式已经足够满足大部分情况了，但是这种方式没有实现兄弟控制器之间的通信方式，所以引出了事件的方式 。基于事件的方式中我们可以里面作用的$on,$emit,$boardcast这几个方式来实现，其中$on表示事件监听，$emit表示向父级以上的 作用域触发事件， $boardcast表示向子级以下的作用域广播事件。参照以下代码：

向上传播事件

从这个用法我们可以引申出一种用于兄弟控制间进行通信的方法，首先我们一个兄弟控制中向父作用域触发一个事件，然后在父作用域 中监听事件，再广播给子作用域，这样通过事件携带的参数，实现了数据经过父作用域，在兄弟作用域之间传播。这里要注意的是，通过父元素作为中介进行传递的话，兄弟元素用的事件名不能一样，否则会进入死循环。请看代码：

兄弟作用域之间传播
