So a little bit earlier when we implemented scrolling to the post that we want to,
00:04
we went ahead and uncommented on updated. Just remind ourselves of the problem that we saw when this was in action. So if I come over here and I reply to this discussion, I'm just going to do this a few times and write some more replies in here.
00:20
You can see that this scrolling functionality is working nicely. Now, as long as we've got the post ID in here, what's going to happen is whenever we perform any other action that updates this page component, it's going to go ahead and scroll down to what we have in the query string.
00:36
For example, if I edit this post here and I hit edit, you can see we get scroll down right to the bottom. That's not the behavior we want. We want it to keep focus on the thing that we're on.
00:46
So what we're going to do is swap this out for a watcher instead and explicitly watch the post ID. So let's go up to the top here where we're importing stuff from view and let's import watch instead. We're going to go ahead and get rid of on updated and just make sure it works for this first of all. And we're going to watch the props or from the props, the post ID.
01:07
Now, the callback for this is just going to go ahead and scroll down to that post. And the post that we use is props to post ID, or we can just go ahead and accept this into the closure here, which will have the new value for the post ID.
01:21
So now that we have commented out on updated again and we've reintroduced some other solution, what this is now going to do is scroll down to the top of the page. You can see that works because we've still got our unmounted hook. But if I now go ahead and edit something, notice that the post ID doesn't change.
01:38
So this is staying in the same place. And this is still going to work for everything else. So, for example, if we reply to this discussion, we know that we're going to get redirected and put down to the bottom here.

Overview
Ready to build a forum with Inertia and Laravel?
Why a forum? A forum touches a whole load of concepts that you'll use throughout your development career – particularly on the client-side, where we'll be doing most of the heavy lifting.
So, let's build a clean, modern forum with features like markdown support, code highlighting, advanced filtering, user mentions, full-text search, the ability to mark best answers, and more.
