Vue2.0用 watch 观察 prop 变化(不触发)

export default { props:{ name:{ type:String } }, data () { return {  author: "Jinkey" } }, mounted:function(){ this.author = 'lili' }, watch:{ name:function(){ console.log(this.name); }, author:function(){ console.log('lili'); } }}

<firstcomponent :name="name"></firstcomponent>import firstcomponent from './component/firstcomponent.vue'export default { data () { return {  msg: 'Hello Vue!',  name:'lili' } }, components: { firstcomponent}}
