Vuejs 2.0 子组件访问/调用父组件的方法(示例代码

<template> 
  <div class="isShowing" ref="isShowing"> 
    <div class="menu-wrapper" ref="scroll_warpper" v-show="!hid_show_switch"> 
      <ul ref="scroll_warpper_ul"> 
        <li class="menu-item" @click="goToFatherDetail(233)"> 
        </li> 
      </ul> 
    </div> 
    <v-loading class="isloading" v-show="hid_show_switch"></v-loading> 
  </div> 
</template> 
<script type="text/ecmascript-6"> 
  export default { 
    methods: { 
      goToFatherDetail (itemId) { 
        // this.$parent.$router.push('goToDetail'); 
        console.log('子组件方法走了' + itemId); 
        this.$emit('refreshlines', itemId); / <span style="font-family: Arial, Helvetica, sans-serif;">itemId就是子要传的数据 - 这里很重要,refreshlines就是父组件$on监测的自定义函数不是父组件的自定义函数。/</span> 
      } 
    } 
  }; 
</script> 

<template> 
  <div class="main-wrapper"> 
      <div class="tab-wrapper"> 
        <div class="tab-item"> 
          <router-link to="/isShowing" class="table-item-text">正在热映</router-link>
