vue组件中倒计时，刷新页面不会从头开始

// 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);
  },
