app.vue
  <div id="app">
    <keep-alive exclude="Detail">
      <router-view/>
    </keep-alive>
  </div>

Detail.vue中的子組件Comm.vue
  activated () {
    window.addEventListener('scroll', this.handleScroll)
  },
  deactivated () {
    window.removeEventListener('scroll', this.handleScroll)
  }

vue中在keep-alive中exclude設(shè)置了某個(gè)組件，這個(gè)組件中的子組件不執(zhí)行activated函數(shù)？
這段代碼該如何修改？
