Vue实例:演示input 和 textarea 元素中使用 v-model 实现双向数据绑定

最终效果:

主要代码:

<template>
  <div>
    <p>input 元素:</p>
    <input v-model="message" placeholder="编辑我……">
    <p>消息是: {{ message }}</p>
      
    <p>textarea 元素:</p>
    <p>{{ message2 }}</p>
    <textarea v-model="message2" placeholder="多行文本输入……"></textarea>
  </div>
</template>

<script>
  export default {
    name: 'HelloWorld',
    data () {
      return {
        message: 'nwtxxb',
        message2: '你我他学习吧\r\nvue教程'
      }
    }
  }
</script>

<style scoped>
  h1, h2 {
    font-weight: normal;
  }
  ul {
    list-style-type: none;
    padding: 0;
  }
  li {
    display: inline-block;
    margin: 0 10px;
  }
  a {
    color: #42b983;
  }
</style>

App.Vue:

<template>
  <div id="app">
    <img src="./assets/logo.png">
    <HelloWorld2/>
  </div>
</template>

<script>
  import HelloWorld from './components/HelloWorld'
  import HelloWorld2 from './components/HelloWorld2'
  export default {
    name: 'App',
    components: {
      HelloWorld2
    }
  }
</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>

main.js:

import Vue from 'vue'
import App from './App'

Vue.config.productionTip = false

new Vue({
  el: '#app',
  components: { App },
  template: '<App/>'
})
