I'm triyng to remove an object property using spread syntax rendering a React component. I wonder if there is a way to achieve without adding to much extra code. I'm using {reset,...inputName}
I have a custom hook (useField) for every input in my form. useField also has a reset function for my reset button. But I want to remove the reset property only for the inputs element.
custom hook useField
export const useField = (type) => {
const [value, setValue] = useState('')
const onChange = (event) => {
setValue(event.target.value)
}
const reset = () => {
setValue('')
}
return {
type,
value,
onChange,
reset
}
}
react form
const MyForm = (props) => {
const content = useField('text')
const author = useField('text')
const info = useField('text')
const handleClick = () => {
content.reset()
author.reset()
info.reset()
}
return (
<div>
<h2>create a new anecdote</h2>
<form onSubmit={handleSubmit}>
<div>
content
<input {reset,...content} />
</div>
<div>
author
<input {reset,...author} />
</div>
<div>
url for more info
<input {reset,...info} />
</div>
<button>create</button>
<input type="reset" value='reset' onClick={handleClick} />
</form>
</div>
)
}

For future reference, what may work for OP are changes similar to below:
const { reset: resetContent, ...content} = useField('text')
const { reset: resetAuthor, ...author} = useField('text')
const { rest: resetInfo, ...info} = useField('text')
const handleClick = () => {
resetContent();
resetAuthor();
resetInfo();
};
.

.
<div>
content
<input {...content} />
</div>
.
.
.
Explanation
- the object returned from
useField
is destructured - the
reset
prop is separated and renamed asresetContent
(orresetAuthor
,resetInfo
, as required) - the rest of the props go into the
content
variable (orauthor
,info
variables, as required) - when rendering in the JSX, the
content
is used
Thus, effectively the reset
prop from useField
was 'removed'
(technically, it was just separated, though) in the new content
object.
