在路由的js中加入
scrollBehavior (to, from, savedPosition) { if (savedPosition) { return savedPosition } else { return { x: 0, y: 0 } } },
列如：
export default new Router({ // mode: 'history', mode: 'history', scrollBehavior (to, from, savedPosition) { if (savedPosition) { return savedPosition } else { return { x: 0, y: 0 } } },
