微信小程序实现验证码获取倒计时的效果

 {{time}} 

var interval = null //倒计时函数 Page({ data: { date:'请选择日期', fun_id:2, time: '获取验证码', //倒计时 currentTime:61 }, getCode: function (options){ var that = this; var currentTime = that.data.currentTime interval = setInterval(function () { currentTime--; that.setData({ time: currentTime+'秒' }) if (currentTime <= 0) { clearInterval(interval) that.setData({ time: '重新发送', currentTime:61, disabled: false }) } }, 100) }, getVerificationCode(){ this.getCode(); var that = this that.setData({ disabled:true }) }, })
