监听router控制滚动条

1、main.js

router.afterEach((to, from, next) => {
    window.scrollTo(0, 0);
});

2、watch

 watch: {
            route (newval, oldval) {
                if (newval.path === '/betting' || newval.path === '/trend' || newval.path === '/lotResult') {
                    document.body.scrollTop = '200';
                }
                this.setAllShow(false);
            }
        },
