Allow numbers after data-
in custom attributes fixes #2329
#5216
Conversation
Well, while we're at it: it's not just numbers. If this gets fixed, then it should not just add another special case but allow all valid attributes.

@nLight Can you update as per @Prinzhorn @spicyj This PR has been open for nearly two weeks. Any objections to us merging? |
It's not even done yet. |
I'll update |
@nLight Ping. Would love to get this in. |
@nLight updated the pull request. |
Sorry it took so long, guys. I have no idea how to test this range \u10000-\uEFFFF but everything else seems to be working. |
@nLight updated the pull request. |
Looks good to me. I'll leave it open for a day so everyone has a chance to see this before merging. |
The code points U+10000 and beyond are represented in UCS-2 as two Unicode characters: See https://mathiasbynens.be/notes/javascript-encoding for more details. I think you should be able to test that emoji in attributes like "data-😊" works. I don't think your current code works with this. If you can't get this to work properly, I would be okay dropping the |
Hey @spicyj, I've read this article. Turns out the code works: |
Well now I'm really confused. I did not expect
to match anything… |
Yes, mine does that too. That's why I'm confused. But @zpao is confused about why you're not hitting this check: react/src/renderers/dom/shared/DOMPropertyOperations.js Lines 23 to 45 in d6a547f
|
Because this function doesn't test props name only tag name to contain '-'
|

Ugg, this is why I wish we didn't have to do our own validation. Ok, sounds to me like the next step is to write two unit tests (one for a div, one for a custom-component) which performs initial render and an update render, verify no warnings are emitted. That will likely include expanding the whitelist that @spicyj and @zpao mentioned. |
Working on the attribute name check function, tests will follow. |
After patching the function I discovered that Chrome, Safari and Firefox don't like
Simple code to reproduce:

Good with me. |

Is this different from ATTRIBUTE_NAME_CHAR
? Should that variable be shared?

It's the same. Any suggestions where to put this variable? Both of them require DOMProperty
var DOMProperty = require('DOMProperty');

Idk, I'd probably put it into HTMLDOMPropertyConfig (since it feels sort of config like). DOMPropertyOperations can then require HTMLDOMPropertyConfig.ATTRIBUTE_NAME_CHAR.

DOMProperty is fine. DOMPropertyOperations shouldn't depend on HTMLDOMPropertyConfig directly.

Allow numbers after `data-` in custom attributes fixes #2329
Hi guys,
I decided to start with a good first bug: #2329
With that fix it's now possible to have a number after a data- i.e.
data-1000-number
in a custom attribute. That should be it, am I missing something?Thanks,
Dmitriy
