组件内导航之beforeRouteUpdate的使用

export default{
   data(){
         return {}
  },
   beforeRouteUpdate(to,from,next){
        console.log(to,from,next)
        if(to.fullPath!=from.fullPath){
            next()
            this.changeUser()
        }
    },
    methods:{
         changeUser(){
            getUserBaseInfo({userId:this.$route.params.id}).then(res=>{
            if(res.success){
                this.stuInfo = res.data;
            }else{
                this.$message.error(res.message)
            }
            
        })
        }  
    }  
}
