nvue input使用blur()方法会意外导致@focus触发

<template>  
    <view class="content">  
    <text>输入到最后一个后自动blur(快速输入会导致focus在blur后触发)</text>  
    <view v-for="key in 4" :key="key" style="background-color: #007AFF;margin-top: 20rpx;">  
      <input :ref="'input'+key" :value="s_code[key - 1]" @focus="inputFocus" @blur="inputBlur" @input="input(key)" type="number" />  
    </view>  
    </view>  
</template>
