The setInterval timer is used in the vue method, which is still executed after leaving the page. I would like to ask how to solve the problem.

this is the timer used in the methods method

 async verScheme(index,row){
        var uuid =  this.getUuid();
        try {
          let ret = await this.$Api.OperationAccess.SystemAccess.Verification({
            id: row.id,
            uuid : uuid,
          })
           this.dialogFormVisible1 = true;
            this.interval =setInterval(()=> {
              this.log(uuid);
            },1000);
        }catch ( ret ){
          this.$message.error( ret.msg ? ret.msg : " : " + ret )
        }
      }

this is using beforeDestory ()

created(){
      this.Init();
      this.timer = this.interval;
    },

    beforeDestroy() {
      if (this.timer) { // 
        clearInterval(this.timer); //
      }
    },

Javascript vue.js setinterval

did your this.interval return the correct timer

you can try requireanimationframe

the reference to your timer is not saved correctly

an opinion on your way of writing

since your timer has been stored with a interval , why save it to timer in the created cycle
you execute the init function during the created cycle. Can you make sure that this function is finished before you execute the following interval assignment to timer ? If there is no guarantee, then you should know what this timer holds

your way of writing is rather troublesome. It is recommended that you do not have to save it in an instance, save memory, and you do not even have to write code in the beforDestory cycle

//
let timer = setInterval(() => {
    //
} 1000)
//thisvue
this.$once('hook:beforeDestory', function() {
    clearInterval(timer)
})
