前言
倒计时的运用场景：获取手机验证码倒计时、获取邮箱验证码倒计时等场景，废话不多说，开始吧。
之前给大家介绍过Vue3 实现验证码倒计时功能(刷新保持状态)，需要的朋友点击查看。
实现效果
实现代码 html（重要部分）
<template>
<el-button v-if="!sms.disabled" color="#f38301" type="default" @click="send"><span style="color:#eed2b0;">发送验证码</span></el-button>
<el-button v-else type="default" color="#f38301" disabled><span style="color:#eed2b0;">{{ sms.count }} 秒后重新发送</span></el-button>
</template>js（重要部分）
<script lang="ts" setup>
// 验证码计时器
const sms = reactive({
disabled: false,
total: 60,
count: 0
})
// 计时器处理器
const timerHandler = () => {
sms.count = sms.total
sms.disabled = true
let timer = setInterval(() => {
if (sms.count > 1 && sms.count <= sms.total) {
sms.count--
} else {
sms.disabled = false
clearInterval(timer)
}
}, 1000)
}
// 推送
const send = () => {
if (formLabelAlign.username === '') {
ElMessage.error("电子邮件为空")
} else {
// 计时器处理器
timerHandler()
// 加载ui
const loadingInstance1 = ElLoading.service({fullscreen: true})
// api 请求
return emailRegisterApi(formLabelAlign.username).then(res => {
// 关闭加载
loadingInstance1.close()
}).catch(() => {
// 关闭加载
loadingInstance1.close()
})
}
</script>

</style>PS：Vue3 - 验证码按钮倒计时实现
使用 primevue 作为 UI 框架，没有按钮加载（失效）倒计时的配置项。需要自己实现。
setup() {
const btn_vrft = reactive({
label: '获取验证码',
loading: false
});
function countDownTimer(count) {
return new Promise(resolve => {
console.log("Start")
if(count>0){
setTimeout(() => {
count--
countDownTimer(count)
}, 1000)
btn_vrft.label = count.toString()
}
else {
btn_vrft.loading=false
btn_vrft.label='获取验证码'
}
resolve(count)
console.log(count)
console.log("End")
})
};
async function handleVerification(){
btn_vrft.loading=true
await countDownTimer(60)
};
return {
btn_vrft,
handleVerification
}
}按钮组件：
<Button @click="handleVerification" :label="btn_vrft.label" :loading="btn_vrft.loading" />到此这篇关于Vue3 实现验证码倒计时的文章就介绍到这了,更多相关Vue3 验证码倒计时内容请搜索编程网以前的文章或继续浏览下面的相关文章希望大家以后多多支持编程网！
