It seems that writing @mousewheel has no effect, I hope God can give me some advice

Kuoyi, how did you write it specifically

Okay, I made a mistake myself, because it was added to a component tag, it should be written @mousewheel.native~~

You can write a command to monitor it yourself

Vue.directive('scroll', {
  // 当绑定元素插入到 DOM 中
  inserted: function (el,binding) {
    var cb = binding.value
    el.addEventListener('mousewheel',function(e){
      var direction = e.deltaY>0?'down':'up'
      cb(direction)
    })
  }
})

new Vue({
  el:'#app',
  methods:{
    scrollFn:function(direction){
      console.log(direction)
    }
  }
})
