vue 监听某div滚动条的滚动事件

监听此div , 定义ref  
ref="rightContent" @mousewheel="scrool">

mounted: function(){
  //在mounted钩子函数绑定滚动条事件
  this.$refs.rightContent.addEventListener('scroll', this.scrool);
  
},

methods: {
  scrool(){
    console.log('===scrool===') 
    let scrolled = this.$refs.rightContent.scrollTop;
    console.log(scrolled ) 
  } 
},

 

注：只写@mousewheel="scrool"  鼠标滚动事件，不能监听到：用鼠标拖动滚动条
