效果如图：

代码如下：

keyboard.vue

<template> 
 <p class="keyboard" v-show="showKeyboard" v-clickoutside="closeModal"> 
  <p v-for="keys in keyList"> 
   <template v-for="key in keys"> 
    <i v-if="key === 'top'" @click.stop="clickKey" class="iconfont icon-zhiding tab-top"></i> 
    <i v-else-if="key === '123'" @click.stop="clickKey" class="tab-num">123</i> 
    <i v-else-if="key === 'del'" @click.stop="clickKey" id="del" class="iconfont icon-delete key-delete"></i> 
    <i v-else-if="key === 'blank'" @click.stop="clickKey" class="iconfont icon-konggejian-jianpanyong tab-blank"></i> 
    <i v-else-if="key === 'symbol'" @click.stop="clickKey" class="tab-symbol">符</i> 
    <i v-else-if="key === 'point'" @click.stop="clickKey" class="tab-point">·</i> 
    <i v-else-if="key === 'enter'" @click.stop="clickKey" class="iconfont icon-huiche tab-enter"></i> 
    <i v-else @click.stop="clickKey" >{{key}}</i> 
   </template>
