微信小程序分、秒倒计时，补零

Posted 2023-03-18

参考技术A <view>min:sec</view>

//计时器,cycleTime为豪秒数

  timerSec(cycleTime)

    var that = this

    let intervalsec = null //倒计时函数

    intervalsec = setInterval(function()

      cycleTime--;

      that.setData(

        min: parseInt(cycleTime / 60) < 10 ? '0' + parseInt(cycleTime / 60) : parseInt(cycleTime / 60),

        sec: (cycleTime % 60) < 10 ? '0' + (cycleTime % 60) : (cycleTime % 60),

      )

      if (cycleTime == 0)

        clearInterval(intervalsec)

     

    , 1000)

微信小程序获取验证码倒计时

  getVerificationCode: function() {
    var that = this;
    var currentTime = that.data.currentTime;
    that.setData({
      codename: currentTime + ‘秒‘,
      disabled:true
    })
    var interval = setInterval(function() {
      that.setData({
        codename: (currentTime - 1) + ‘秒‘
      })
      currentTime--;
      if (currentTime <= 0) {
        clearInterval(interval)
        that.setData({
          codename: ‘重新获取‘,
          currentTime: 60,
          disabled: false
        })
      }
    }, 1000)
