在vue項目中如何使用錨點呢？
在vue-router中定義 scrollBehavior
scrollBehavior (to, from, savedPosition) {
if (savedPosition) {
// savedPosition is only available for popstate navigations.
return savedPosition
} else {
const position = {}
// new navigation.
// scroll to anchor by returning the selector
if (to.hash) {
position.selector = to.hash
}
// 如果meta中有scrollTop
if (to.matched.some(m => m.meta.scrollToTop)) {
// cords will be used if no selector is provided,
// or if the selector didn't match any element.
position.x = 0
position.y = 0
}
// if the returned position is falsy or an empty object,
// will retain current scroll position.
return position
}
}
