    <style>

        .show{

            width:100px;

<body>

<div id="app">

        <button @click="fhide">show/hide</button>

        {{hidef}}

       <son :test="hidef"></son>

    </div>

</template>

<template id="son">

    Vue.component('father',{

由父到子

子组件通过props抛出一个自定义组件标签属性。

父组件通过子组件的组件标签属性将需要的 数据传递过去。

子组件通过抛出的标签属性来调用这个值。
