directive组件作用域 #14

false，继承父作用域（默认值），父能影响子，子也能影响父;
true，继承父作用域，并且创建自己的作用域（子作用域），父能影响子，子不能影响父;
{}，创建一个全新的隔离作用域，父子互不影响；

AngularJS Directive 隔离 Scope 数据交互

Wscats · 2016-08-17T07:43:52Z

html
**=**双向数据绑定，注意此时name属性值的变量要带{{}}
<wsscat2 name="{{name}}"></wsscat2>
js

scope: {
        name:"="
        },

html
**@**当方向影响，父能影响子，但子不能影响父
<wsscat2 name="name"></wsscat2>

scope: {
        name:"@"
},

一定要把绑定的值放在属性上面作为媒介
属性值不能设置为如data-name的data-前缀的值
如果是设置为abc-name等格式
组件里面scope属性传递的对象，里面的name属性值要遵守驼峰的写法

scope: {
        name:"@abcName"
},
