I have a function that gives me an array of strings who depends if checkboxes are checked or not.
I want to fill another array with hooks method like so
const [firstArray, setFirstArray] = useState([]);
...
const myFunction = (array) => {
// array like so => [firstString, secondString, etc..]
array.forEach(arr => {
setFirstArray([...firstArray, ...arr])
// if function array change i want to filter firstArray
if(??){
setFirstArray(
firstArray.filter(check => check !== arr)
)
}
}
}
which way is the best ?
You just should update your state whenever the onChange function is triggered:
const App = () => {
const [selectedOptions, setSelectedOptions] = useState([]);
const onChange = (checkedValues) => {
setSelectedOptions(checkedValues);
};
return (
<div className="App">
<Checkbox.Group
options={options}
defaultValue={selectedOptions}
onChange={onChange}
/>
</div>
);
};
