Here’s one photo from each month in 2024

2004 was the first year of the future

I enjoyed reading through these essays about the web of twenty years ago: music, photos, email, games, television, iPods, phones…

Much as I love the art direction, you’d never know that we actually had some very nice-looking websites back in 2004!

The datalist element is good. It was a bit bumpy there for a while, but browser implementations have improved over time. Now it’s by far the simplest and most robust way to create an autocompleting combobox widget.

Hook up an input element with a datalist element using the list and id attributes and you’re done. You can even use a bit of Ajax to dynamically update the option elements inside the datalist in response to the user’s input. The browser takes care of all the interaction. If you try to roll your own combobox implementation, it’s almost certainly going to involve a lot of JavaScript and still probably won’t account for all use cases.

Safari on iOS—and therefore all browsers on iOS—didn’t support datalist for quite a while. But once it finally shipped, it worked really nicely. The options showed up just like automplete suggestions above the keyboard.

But that broke a while back.

The suggestions still appeared, but if you tapped on one of them, nothing happened. The input element didn’t get updated. You had to tap on a little downward arrow inside the input in order to see the list of options.

That was really frustrating for anybody on iOS using The Session. By far the most common task on the site is searching for a tune, something that’s greatly (progressively) enhanced with a dynamically-updating datalist.

I just updated to iOS 18 specifically to see if this bug has been fixed, and it has:

Fixed updating the input value when selecting an option from a datalist element.

Hallelujah!

But now there’s some additional behaviour that’s a little weird.

As well as showing the options in the autocomplete list above the keyboard, Safari on iOS—and therefore all browsers on iOS—also pops up the options as a list (as if you had tapped on that downward arrow). If the list is more than a few options long, it completely obscures the input element you’re typing into!

I’m not sure if this is a bug or if it’s the intended behaviour. It feels like a bug, but I don’t know if I should file something.

For now, I’ve updated the datalist elements on The Session to only ever hold three option elements in order to minimise the problem. Seeing as the autosuggest list above the keyboard only ever shows a maximum of three suggestions anyway, this feels like a reasonable compromise.
