vue车牌搜索组件使用方法详解
一个简单的车牌输入组件（vue），供大家参考，具体内容如下
代码：
vue代码：
<template>
<div class="pulls">
<!-- 精确车牌搜索 -->
<div class="enterPlate">
<div class="enterBox" :style="{width:noRightPart==='on'?'100%':''}">

<div :class="['alb',EnterPlateNumber.input.whitchKey===1?'isEntering':'']" @click.stop="enterAlbn">{{EnterPlateNumber.input.secondWord}}</div>
<div :class="['plate',EnterPlateNumber.input.whitchKey===2?'isEntering':'']" :style="{width:noRightPart==='on'?'350rpx':''}" @click.stop="enterLastn">{{EnterPlateNumber.input.lastWords}}</div>
</div>
<div class="doneBox">

因为这里用了独家的框架，所以根据需要把相应的生命周期函数放到正常的vue项目的位置，把event就写成正常的函数，methods就是i正常的methods里面的方法，model就是data里return的数据
