Detailed explanation of scrolling behavior of Vue-Router

This time I will bring you the scrolling behavior of Vue-Router Detailed explanation of use, what are the precautions when using Vue-Router scrolling behavior, the following is a practical case, Let’s take a look.

Scroll behavior

Using front-end routing, when switching to a new route, you want the page to scroll to the top, or to maintain the original scroll position, just like reloading the page. vue-router can do it, but better. It allows you to customize how the page scrolls when routing is switched.

Note:

This feature is only available in HTML5 history mode. When creating a Router instance, you can provide a scrollBehavior method:

var router = new VueRouter({
  routes: [...],
  scrollBehavior (to, from, savedPosition) {
    // return 期望滚动到哪个的位置
  }
})

The scrollBehavior method receives to and from routing objects. The third parameter savedPosition is available only if popstate

Navigation

(triggered by the browser's forward/back buttons). This method returns the object information of the scroll position, which looks like this:

{ x: number, y: number }

• { selector: string }
If a false boolean value is returned, or an empty object is returned, no scrolling will occur.

Example:

scrollBehavior (to, from, savedPosition) {
 return { x: 0, y: 0 }
}

For all route navigation, simply let the page scroll to the top.

Return to savedPosition, when pressing the back/forward button, it will behave like the browser's native behavior:

scrollBehavior (to, from, savedPosition) {
 if (savedPosition) {
  return savedPosition
 } else {
  return { x: 0, y: 0 }
 }
}

If you want to simulate the behavior of "scroll to anchor":

scrollBehavior (to, from, savedPosition) {
 if (to.hash) {
  return {
   selector: to.hash
  }
 }
}
