本文實例為大家分享了vue實現(xiàn)鍵盤輸入支付密碼功能的具體代碼，供大家參考，具體內(nèi)容如下

支付密碼功能界面如下圖：

主要代碼如下：

<template>
 <div class="pay-tool">
  <div class="pay-tool-title border-bottom">
   <span class="icon icon-back" @click="backHandle"></span><strong>請輸入交易密碼</strong>
  </div>
  <div class="pay-tool-content">
   <div class="pay-tool-inputs">
    <div class="item" v-for="i in items"><span class="icon_dot" v-if="password[i]"></span></div>
   </div>
   <div class="pay-tool-link"><router-link class="link" to="/getP">忘記密碼？</router-link></div>
  </div>
  <div class="pay-tool-keyboard">
   <ul>
    <li @click="keyUpHandle($event)" v-for="val in keys">
     {{ val }}
    </li>
    <li class="del" @click="delHandle"><span class="icon-del"><</span></li>
   </ul>
  </div>
 </div>
</template>

<script>
 const keys = () => [1, 2, 3, 4, 5, 6, 7, 8, 9, '', 0]
 // let sendFlag = true // 防止重復(fù)發(fā)送密碼
 export default {
  data () {
   return {
    items: [0, 1, 2, 3, 4, 5],
    keys: keys(),
    password: []
   }
  },
  methods: {
   backHandle () {
    this.clearPasswordHandle() // 返回時清除password
    this.$emit('backFnc') // 返回上級
   },
   keyUpHandle (e) {
    let text = e.currentTarget.innerText
    let len = this.password.length
    if (!text || len >= 6) return
    this.password.push(text)
    this.ajaxData()
   },
   delHandle () {
    if (this.password.length <= 0) return false
    this.password.shift()
   },
   ajaxData () {
    if (this.password.length >= 6) {
     console.log(parseInt(this.password.join(' ').replace(/\s/g, '')))
    }
    return false
   },
   clearPasswordHandle: function () {
    this.password = []
   }
  }
 }
