vue车牌号键盘输入组件

我爱模板网在之前发过过关于车牌号键盘的js插件，但这个是基于jQuery和layer-mobile的，如果用在vue项目中，感觉不太划算，毕竟要引入这么多，还要使用jQuery库。还好，在《简书》找到了一篇基于vue车牌号键盘的文章，感谢晴天丶麻油叶的无私奉献。经过简单改造（如输入第一个中文后，自动切换到英文键盘，将删除键加上等），顺利用上了这个功能：


组件代码（直接新建vue文件，放到项目的components目录）：

<template lang="">
  <div>
    <div class='panel-wrap'  v-if="isShow" data-value="exit"  @click='colse_da'>
      <div class="vehicle-panel" :style="{background:backgroundColor}">
        <div class='topItem'>
          <span class='check'  @click='check'>中/英</span>
          <span class='contentShow'>{{oinp}}</span>
          <span class='exit' @click='vehicleTap("exit")'>取消</span>
        </div>
        <!--省份简写键盘-->
        <div v-if="keyBoardType === 1">
          <div class="vehicle-panel-row">
            <div    class='vehicle-panel-row-button' :style="{border:buttonBorder}" v-for="(item,idx) in keyVehicle1" @click='vehicleTap(item)' :key="idx+item">{{item}}</div>
