Vue父子模版传值及组件传值的三种方法

<div id="example">
  <my-component></my-component>
</div>
<script src="../node_modules/vue/dist/vue.js"></script>
<script>
  //向子组件传递数据
  //省略extend方法，vue内部调用
  Vue.component('my-component', {
    //模板里不支持驼峰的属性写法，需要转换为‘-'连接的属性写法
    data:function(){
      return{
        parentMsg: '雨歇微凉'
      }
    },
    template: '<div>'
        +'<input v-model="parentMsg">'
        +'<br>'
        +'<child-component :my-message="parentMsg"></child-component>'
        +'</div>',
    components: {
      'child-component': {
        props: ['myMessage'],
        template: '<div>{{myMessage}}</div>'
      }
    }
  });
  // 创建根实例1
  new Vue({
    el: '#example'
  });
</script>

<div id="example">
  <my-component></my-component>
</div>
<script src="../node_modules/vue/dist/vue.js"></script>
<script>
  //向子组件传递数据
  //省略extend方法，vue内部调用
  Vue.component('my-component', {
    data:function(){
      return {
        name:'xiaoming',
        age:20
      }
    },
    //模板里不支持驼峰的属性写法，需要转换为‘-'连接的属性写法
    template: '<div >{{name}}Parent</div><child1-component v-bind:msg-name="name"></child1-component>',
    components: {
      'child1-component': {
        // 声明 props
        props: ['msgName'],
        template: '<div>A child-111111 component!{{msgName}}</div>'
      }
    }
  });
  // 创建根实例1
  new Vue({
