本文实例为大家分享了微信小程序验证码倒计时效果的具体代码，供大家参考，具体内容如下
如果写过js的倒计时，那么小程序中使用也是差不多的；
代码：
data: {
daojishi:60,
inter:''
},
daojishi: function () {
this.data.inter = setInterval((res) => {
this.fun();
}, 1000);
},
fun: function () {
let t = this.data.daojishi;
t--;
this.setData({
daojishi: t
})
if (t <= 0) {
// location.href = "https://www.baidu.com";
clearInterval(this.data.inter);
this.setData({
isyanzhengma: true
})
}
},手机登录、填手机号获取验证码，倒计时后重新获取效果
描述：
输入正确的手机号并且输入验证码后，手机登录按钮变为红色可点击状态；自动验证输入的手机号是否为合法手机号；点击获取动态码后开始60秒倒计时后才可以再次获取动态码；
效果图：
代码：
