本文实例为大家分享了微信小程序实现接收验证码的具体代码，供大家参考，具体内容如下
效果如下图：
wxml部分如下：
<!--验证码-->
<view class="mod t-name" style='position:relative'>
<text class="key">验证码:</text>
<input type="digit" bindinput="bindKeyInput" data-inputname="phoneCode" value='{{phoneCode}}' class="input" maxlength="100" placeholder="请输入手机验证码" />
<text class='logbook'></text>
<text class='getkey' bindtap="clickGainCode">{{tipsCode}}</text>
</view>css部分代码如下：
.mod{
display: flex;
flex-direction: row;
justify-content: space-between;
align-items: center;
height: 100rpx;
padding: 0 20rpx;
border-bottom:1rpx solid #ccc;
box-sizing: border-box;
}
.mod .key{
font-size: 28rpx;
font-weight: bold;
text-align: right;
width: 160rpx;
}
.t-name{
background-color: rgb(254,254,254);
box-sizing: border-box;
}
.t-name .input{
width: 540rpx;
font-size: 28rpx;
margin-left: 30rpx;
}
.logbook {
font-size: 24rpx;
width: 150rpx;
text-align: right;
font-weight: bold;
}
.getkey {
width: 200rpx;
position: absolute;
right: 0rpx;
text-align: center;
color: rgb(31, 45, 210);
font-size: 24rpx;
border-left: 1px solid #f0f0f0;
}js的data里定义如下内容：
data: {
tipsCode: "获取验证码",
timeNum: 60,
clikType: false,
phone: null,
phoneCode: null,
}获取验证码方法如下：
bindKeyInput: function(e) {
this.data[e.currentTarget.dataset.inputname] = e.detail.value;
this.setData(this.data);
},
//获取验证码时的显示时间
getTime() {
var that = this;
var timer = setInterval(function() {
that.data.timeNum--;
if (that.data.timeNum <= 0) {
that.setData({
tipsCode: "重新获取验证码",
timeNum: timeOut,
clikType: false
});
clearInterval(timer);
} else {
that.setData({
tipsCode: "重新发送" that.data.timeNum "秒",
})
}
}, 1000)
},
//输入手机号获取验证码
gainCode() {
var that = this;
if (this.data.phone == '' || this.data.phone == null) {
wx.showToast({
title: '手机号不能为空',
icon: 'none',
})
} else {
that.setData({
clikType: true
})
if (this.data.timeNum < timeOut) {
} else {
wx.request({
url: wxapp_api_url '/common/getCode',
header: {
'content-type': 'application/x-www-form-urlencoded'
},
method: "get",
data: {
phone: this.data.phone
},
success: function(res) {
that.getTime();
}
})
}
}
},
// 点击获取手机验证码
clickGainCode(e) {
if (!this.data.clikType) {
this.gainCode();
}
},以上就是本文的全部内容，希望对大家的学习有所帮助，也希望大家多多支持Devmax。
