Vue实现ATM机模拟功能
使用Vue.js实现ATM机模拟功能需要结合组件化开发、状态管理以及用户交互逻辑。以下是关键实现步骤:
核心组件结构
创建以下Vue组件构建ATM界面:
CardReader.vue:模拟银行卡插入/退出PinPad.vue:数字键盘输入密码AccountDisplay.vue:显示账户余额和交易记录OperationMenu.vue:提供取款/转账/查询等操作选项CashDispenser.vue:模拟现金吐出动画
<!-- ATM.vue 主组件示例 -->
<template>
<div class="atm-machine">
<CardReader @card-inserted="handleCardInsert"/>
<PinPad v-if="pinRequired" @pin-entered="verifyPin"/>
<OperationMenu v-if="authenticated" :balance="accountBalance"/>
<CashDispenser v-if="dispensingCash" :amount="withdrawalAmount"/>
</div>
</template>
状态管理设计
使用Vuex或组合式API管理ATM状态:
// store/atm.js
const state = {
isAuthenticated: false,
currentCard: null,
accountBalance: 10000,
transactionHistory: [],
inputPin: ''
}
const mutations = {
SET_AUTHENTICATED(state, status) {
state.isAuthenticated = status
},
WITHDRAW(state, amount) {
state.accountBalance -= amount
}
}
关键交互逻辑实现
密码验证流程:
methods: {
verifyPin(enteredPin) {
if(enteredPin === this.storedPin) {
this.$store.commit('SET_AUTHENTICATED', true)
} else {
this.attempts++
if(this.attempts >= 3) {
this.ejectCard()
}
}
}
}
取款操作处理:
handleWithdrawal(amount) {
if(amount > this.accountBalance) {
this.errorMessage = '余额不足'
} else {
this.$store.commit('WITHDRAW', amount)
this.dispensingCash = true
setTimeout(() => {
this.printReceipt()
}, 2000)
}
}
动画效果实现
使用Vue过渡动画增强用户体验:
<transition name="cash-dispense">
<div v-if="dispensing" class="cash-stack">
<!-- 现金图标 -->
</div>
</transition>
<style>
.cash-dispense-enter-active {
animation: dispense 0.5s;
}
@keyframes dispense {
0% { transform: translateY(-100px); opacity: 0; }
100% { transform: translateY(0); opacity: 1; }
}
</style>
安全增强措施
- 实施PIN输入遮挡显示
- 交易完成后自动清除敏感数据
- 添加操作超时自动退卡机制
- 使用Vue的
beforeRouteLeave守卫防止意外导航
data() {
return {
timeoutTimer: null,
inactiveTimeout: 30000
}
},
mounted() {
this.resetTimeout()
},
methods: {
resetTimeout() {
clearTimeout(this.timeoutTimer)
this.timeoutTimer = setTimeout(() => {
this.ejectCard()
}, this.inactiveTimeout)
}
}

通过以上架构可实现包含基本存款、取款、转账、查询功能的ATM模拟系统,可根据需求扩展支票存款、外币兑换等高级功能。
