vue里面如何使用cnzz统计每个页面

在main.js中加入

router.beforeEach((to, from, next) => {
  if (document.getElementById('script1')) {
    document.body.removeChild(document.getElementById('script1'))
  }
  if (document.getElementById('script2')) {
    document.body.removeChild(document.getElementById('script2'))
  }

  const script1 = document.createElement('script')
  script1.id = `script1`
  script1.src = `http://s19.cnzz.com/stat.php?id=xxx&web_id=xxx`
  script1.language = 'JavaScript'
  document.body.appendChild(script1)
  const script2 = document.createElement('script')
  script2.id = `script2`
  script2.src = `http://c.cnzz.com/core.php?web_id=xxx&t=z`
  script2.language = 'text/javascript'
  script2.charset = 'utf-8'
  document.body.appendChild(script2)
  next()
})
