Issue #362 (scrollRestoration, Frameworks, React Tools, Build)
A feature of the history API that has been around for a while that you may not have heard of is the history.scrollRestoration property. This property does exactly what the name implies: Allows you to restore the scroll position of a previously visited page in the browser's history, as opposed to jumping back to a previous scroll position.
This might be useful in dynamic apps where the content is constantly changing and a scroll jump might not be desired.
You can get or set the current scrollRestoration value:
console.log(history.scrollRestoration); // auto (default)
history.scrollRestoration = 'manual';
From what I can tell, this works fine in Chromium browsers but doesn't seem to work in Firefox, even though Firefox apparently supports the feature.
To test this out, I put together two simple demo pages:
In both cases, you'll want to perform the same actions, as described on the page, so you can see the difference:
- Scroll down to item 86, click the link
- On the subsequent page, use your browser's back button to go back to the previous page
On the default demo, you should see the page go back to its previously scrolled location (where you can see item 86). But in the second demo, where I'm setting the history.scrollRestoration property to 'manual', you'll notice that the scroll position is restored back to the top of the page once you return using the back button. As mentioned, Firefox doesn't seem to honor the manual value when returning via the back button.
Maybe there's something about this property that I don't understand, but I filed a bug report for Firefox to see if this is something that should be corrected. This looks like a useful little feature but it's not very enticing when the behaviour is different in major browsers.
