vue router 相同组件跳转

// methods
            scrollTop() {
            // 回到顶部
                var scrollTop = window.pageYOffset || document.documentElement.scrollTop || document.body.scrollTop;
                var setI = setInterval(() => {
                    scrollTop = scrollTop - scrollTop / 10;
                    window.scrollTo(0, scrollTop);
                    // console.log(scrollTop);
                    if (scrollTop <= 1) {
                        clearInterval(setI)
                    }
                }, 10);
            },
            pushInfo(tbId) {

                this.$router.push({

        watch: {
