So Im having problems with a form in which takes in text inputs to be set on an object. This object will then be updated in a hashmap of <key, object>.
So far, I can type in the input areas, but if I add another item in the hashmap which generates another div with the input elements it will contain the same value of the previous inputs.
So I need a way to reset those labels within the form and a way to update the hashmap.
I got an updateMap function, but I don't know where to place it for it to await the changes.
Edit: I need to reset the state of link, but when I do a function for it. It says something about preventing infinite loops.
export default function Admin() {
const [link, setLink] = useState({ name: "", link: "" });
const [links, setLinks] = useState(new Map());
const clickAddLink = () => addToMap(links.size + 1, link);
const deleteOnMap = (key) => {
setLinks((prev) => {
const newState = new Map(prev);
newState.delete(key);
return newState;
});
};
const getName = (key) =>
{
let linkFromKey = links.get(key)
return linkFromKey.name
}
const getLink = (key) =>
{
let linkFromKey = links.get(key)
return linkFromKey.link
}
const addToMap = (key, value) => {
setLinks((prev) => new Map([...prev, [key, value]]));
};
const updateMap = (key, value) => {
setLinks((prev) => new Map([...prev, [key, value]]));
};
const clear = () => {
setLinks((prev) => new Map(prev.clear()));
};
.... skipping code ....
<div>
{console.log(link.name)}
{console.log(link.link)}
{[...links.keys()].map((key) => (
<div key={key}>
{links.size > 0 && (
<div>
<form>
<span>Name</span>
<input
type="text"
placeholder={getName(key)}
required
value={link.name}
onChange={(e) =>
setLink({ name: e.target.value })
}
/>
<span>Link</span>
<input
type="text"
placeholder={getLink(key)}
required
value={link.link}
onChange={(e) =>
setLink({ link: e.target.value })
}
/>
</form>
</div>
)}
</div>
))}
</div>
{console.log(link.name)}
{console.log(link.link)}
</div>
```
