I’m currently having trouble with the phone component I’m writing. To be extra vague about it, on my onChange, I’m using a function to move to the next text box. However, when I use my data handler function to raise the value to the parent, it doesn’t work. In addition, by adding my data handler to the individual text boxes, it breaks my next Box function.
//dataHandler => raises state data to parent
//nextBox => moves focus to next text box
//onChange should be here
{
dataHandler(dataProp, e);
nextBox(1);
} />
In the code above, either nextBox works alone, or if I add my handler, then neither work.
I’m also wondering about practices. On other forms, I put this type of handler on single boxes, and it works fine. Since my phone input component has multiple boxes, I’m thinking that onChange won’t work exactly the same regardless.
Any advice, tips, or need to know info?
Ps: I’m on mobile, so I greatly simplified the code I’m using, and the formatting is wonky. Assume that there’s an onChange before the brackets with an (e) =>. My app or lemmy is deleting it on submission.
Thanks! Some quick thoughts.
Recommend staying away from LLMs (Bing, ChatGPT et al.) for now.
Take a look at Sharing data between components from the official React quick start guide.
Try thinking about what is required without thinking about React. I think we need 4 input elements. The value of those elements needs to be concatenated and displayed to the user. Is that right?
From there, we can work out a way to implement what we need using React. Thinking this way helps us start with an even simpler implementation e.g. using just 1 input element instead of 4.
There’s a few things we don’t need right now: unused props like
errorMessage,useRef(), and changing focus.I think what you’re talking about are Signals from Preact? This feature isn’t required right now and it introduces complexity; I personally find it hard to juggle extra concepts in my head especially when starting out with some new tooling.
If you’re still interested we could try writing a couple of basic components that get us part of the way there.
I’ll stay away from the LLMs for now – they’re largely unhelpful anyway.
Right. The other components with a single text box seem to work fine, it’s the multiple boxes in the phone component, and it’s local state, that are confusing me to no end.
Oh, no, when I was talking to Bing it said that the local state interferes with the parent state, so I instead need to bring the parent state into the child. It sort of makes sense? At least the part that local and parent state can interfere with each other makes sense.
Please, I’m all ears. I have a feeling that your approach will help me a lot.
Ok! Just so I’m clear on what we need to do, what do you think the final HTML would look like? Happy to keep comms over Lemmy but email might be easier than fighting with Lemmy’s markdown renderer. My deets are at http://www.olowe.co/about.html in “Contact”
For sure, I’ll send you an email.
edit: sent. Thank you again for the help.
