2021-04-30 vue中定时器setInterval使用

  destroyed() {
    clearInterval(this.positionTimer)// 清除定时器
    this.positionTimer = null
    // 离开路由之后断开websocket连接
    this.webSocketOnClose()
    this.websocketclose()
  },
  methods: {
    // 添加定时器
    addSetInterval() {
      const that = this  // 声明一个变量指向vue实例this,保证作用域一致
      this.positionTimer = setInterval(() => {
        if (that.resultArr.length < that.times) {
          clearInterval(that.positionTimer)
          that.positionTimer = null
          console.log(that.times)
        } else {
          // 分批部署基站
          if (that.times < that.resultArr.length) {
            that.deployBaseStation()
            console.log('渲染数组的第' + that.times + '项')
          }
          that.times++
        }
        console.log(1111111111111)
      }, 500)
    },
