关于elementui form表单过长，看不到未填项

关于form表单过长，点击确定找到未填项并定位到此处

上代码，自辩，我是好使滴

    heightToTop(ele){
      let root = document.body;
      let height=0;
      do{
        height+=ele.offsetTop;
        ele = ele.offsetParent;
      }while(ele!==root)
      return height;
    },
    eleScrollError(){
      this.$nextTick(()=>{
        let isError=document.getElementsByClassName('is-error');
        console.log(isError);
        // document.querySelector(".main2").scrollTo({behavior:"smooth",top:this.heightToTop(isError[0]) - 60},500);
        let container = isError[0].querySelector("input")||isError[0].querySelector("textarea");
        container.focus();
      })
    },

　　//以下没试，自辩
    scrollError(DOM){
      this.$nextTick(()=>{
        let container = document.querySelector(".main2");
    　　 container.scrollTo({behavior:"smooth",top:this.$refs[DOM].offsetTop},500);
      })
    },
