vue组件中倒计时，刷新页面不会从头开始

Posted 2020-11-27 zhaohui-116

开启倒计时，直接保存到vuex中，且存储到本地持久化

// state.js

const runTime = localStorage.getItem(‘time‘);

paymentRunTime:runTime

//  mutations.js

TimeReduction(state) {
    this.timerId = setInterval(() => {
      if (state.paymentRunTime === 0) {
         state.paymentRunTime = 60;
         return clearInterval(this.timerId)
      }
       state.paymentRunTime -= 1;
      localStorage.setItem(‘time‘,state.paymentRunTime)
    },1000);
  },

在需要用到的页面钩子函数调用方法， created（）{ this.$store.commit(TimeReduction) }
