vue计算属性+vue中class与style绑定(推荐)

<div id="example">
    <input type="text" v-model="didi">
    <input type="text" v-model="family">
    <br>
    didi={{didi}},family={{family}},didiFamily={{didiFamily}}
  </div>
  var vm = new Vue({
    el:'#example',
    data:{
      didi:'didi',
      family:'family'
    },
    puted:{
      <!-- 一个计算属性的getter -->
      didiFamily:function(){
        <!-- this指向vm实例 -->
        return this.didi+this.family
      }
    }
  })
