mpa-enhancer v2.3.1
MPA Enhancer
Minimalist JavaScript to make your MPA work that much better
On reloading of a page will scroll back to where the user left off and focus on the last element they were looking at.
At 1.2 kB of minified JavaScript.
Docs
Install by downloading and linking to the script. You can use NPM too and copy it from there.
How it works
It works first by looking for the id on the last focused element. If not
present it will look for the name attribute. If both of those are missing you
can use the mpa-miss (see below) to target a different element to determine
the scroll location. If all those fail then it will scroll to the current
scrolled position of the page — this is not ideal as you can be deleting and
adding elements and this will make the scroll position slightly different.
Attributes
These attributes can enable the enhancer to make special accommodation to your pages.
mpa-target: This will target a different element instead of the active
element. This is useful when the active element is hidden and so the top value
is 0.
<div id="my-id">
<input mpa-target="#my-id" type=hidden name=whatever>
</div>mpa-page-name: This overrides the default page name (the pathname in your
URL). Use it like so:
<body mpa-page-name="my-page-name">mpa-persist: This will persist the page location even when you change pages
and come back later. Use it like so:
<body mpa-persist>mpa-skip-focus: This will skip the focus of the element that you are on on
page refresh. Use it like so:
<input name=my-name mpa-skip-focus>mpa-skip-scroll: This will skip the scrolling of the page. This is useful
when you focus in a location and don't want the scroll to move it to the new
spot. Use it like so:
<input name=my-name mpa-skip-scroll>mpa-miss: This will give a back up location if the ID/name element is no
longer on the page after a refresh. You can supply it a back up location. Use it
like so:
<div id="my-backup-location" mpa-miss="#my-backup-location">
<input name=delete-me>
</div>Change Log
