本文实例为大家分享了微信小程序实现验证码倒计时的具体代码，供大家参考，具体内容如下
wxml代码：
<view class='container'>
<form bindsubmit='denglu'>
<view class='list'>
<view class='left'>
<label>手机号:</label>
<input type='number' name="tel" bindinput='shj' maxlength='11' placeholder='请输入手机号'></input>
</view>
<view class='right'></view>
</view>
<view class='list border'>
<view class='left'>
<label>验证码:</label>
<input type='number' name="code" placeholder='请输入验证码'></input>
</view>
<view class='right'>
<button class='send' wx:if="{{isShow}}" catchtap='send'>发送验证码</button>
<button class='send' disabled='{{true}}' wx:else>{{countdown}}秒后重新发送</button>
</view>
</view>
<button form-type='submit' class='btn'>登录</button>
</form>
</view>
js代码：
const app = getApp()
Page({
/**
* 页面的初始数据
*/
data: {
countdown: 60,
isShow:true
},
//倒计时
count:function(that){
var interval = setInterval(function () {
var countdown = that.data.countdown;
if (countdown == 0) {
that.setData({
isShow: true,
countdown: 60
})
clearInterval(interval)
} else {
countdown--;
that.setData({
isShow: false,
countdown: countdown
})
}
}, 1000)
},
//设置手机号
shj: function (e) {
this.setData({
tel: e.detail.value
})
},
//获取验证码
send: function () {
var that=this;
wx.showToast({
title: '验证码发送成功',
icon: 'none',
duration: 1000,
success: function () {
that.count(that)
}
})
},
//登录
denglu:function(e){
console.log(e.detail.value)
},
/**
* 生命周期函数--监听页面加载
*/
onLoad: function (options) {
},
})
wxss代码：
.list{
background-color: white;
font-size: 32rpx;
padding: 20rpx 30rpx;
display: flex;
justify-content: space-between;
align-content: center;
