今天小編就為大家分享一篇解決vue js IOS H5focus無(wú)法自動(dòng)彈出鍵盤(pán)的問(wèn)題，具有很好的參考價(jià)值，希望對(duì)大家有所幫助。一起跟隨小編過(guò)來(lái)看看吧

IOS不自動(dòng)彈出鍵盤(pán)，必須手動(dòng)觸發(fā)一下focus才行，不能自動(dòng)調(diào)用，所以需要誘導(dǎo)用戶點(diǎn)擊某個(gè)按鈕觸發(fā)focus，最終修改的方法，默認(rèn)隱藏密碼輸入框，隱藏不能用v-if或者是v-show,用position:absolute, top:-1000,然后點(diǎn)擊輸入密碼將top改為視窗內(nèi)，并且調(diào)用focus的方法

代碼如下，有問(wèn)題歡迎評(píng)論

<template>
 <div class="pwdpush-box">
  <h4 class="enter-password" @click="enterPwd">輸入密碼</h4>
  <div class="phonenum-show" :class="pushShow?'':'write-phonenum-1000'">
   <div class="write-phonenum">
    <p @click.prevent="pushShow = false">使用余額支付 8864</p>
    <p>支付密碼：</p>
    <ul class="write-input clearfix">
     <input type="tel" ref="input" maxlength="6" class="realInput" v-model="realInput" autofocus @keyup="getNum()" v-focus @keydown="delNum()">
