js实现自动锁屏功能

// app.vue

data () {

    timer: null,
    isLock: 'false'
  }
},

  this.timer = setTimeout(this.lockPro, this.timeOut)
  // 首次设置操作时间
  localStorage.setItem('moveTime', Date.now())
  // 首次判断状态
  this.modalStatus()
  // 轮询监听状态
  setInterval(this.modalStatus, 1000)
  // 监听鼠标事件
  this.events()
},
methods:{
   events() {
      window.onmousemove = () => {
        // console.log('鼠标移动了')
        if (!this.isLock) {

          this.clearLocaPro('continue')
        }
