判断一个网址，多少时间没被操作

actionListener() {
  var count = 0
  var outTime = 2 // 分钟
  function go() {
    count++
    if (count == outTime * 60) {
      alert('您长时间未操作页面')
      // 此处处理后续操作
    }
  }
  // 页面倒计时
  window.setInterval(go, 1000)
  // 监听鼠标
  var x
  var y
  document.onmousemove = function(event) {
    /* Act on the event */
    var x1 = event.clientX
    var y1 = event.clientY
    if (x != x1 || y != y1) {
      count = 0
    }
    x = x1
    y = y1
  }
  document.onkeydown = function(event) {
    count = 0
  }
},
