vue2.0组件入门

如何定义一个组件

在根目录src/components/文件夹下新建组件的文件夹Footer.vue组件

在Footer.vue中

<template>
    <div class="footer">
        {{name}}
        <button class="btn" @click="che">click</button>
    </div>
</template>
<script>
    export default {
        name:'Footer',
        data() {
            return{
                name:123
            }
        },
        methods:{
            che:function(){
                alert(9999);
            }
        }

    }
</script>
<style type="text/stylus" lang="stylus">
    .footer 
        color red
</style>

在app.vue 中引用此组件

<template>
  <div id="app">
    {{age}}
    <router-view></router-view>
    <Footer></Footer>
  </div>
</template>

<script>
import Footer from './components/Footer/Footer.vue'
export default {
  name: 'app',
  data() {
    return {
      age:111
    }
  },
  components:{Footer}
}
</script>

<style>
#app {
  font-family: 'Avenir', Helvetica, Arial, sans-serif;
  -webkit-font-smoothing: antialiased;
  -moz-osx-font-smoothing: grayscale;
  text-align: center;
  color: #2c3e50;
  margin-top: 60px;
}
</style>
