Getting below error while trying to update a preloaded value onchange using useState inside map
React Hook "useState" cannot be called inside a callback. React Hooks must be called in a React function component or a custom React Hook function react-hooks/rules-of-hooks
I'm trying to display a value from data array on a custom date field and on change update it to new selected date. When I'm trying to use a useState hook inside a map, I'm getting the below error. I'm a beginner in react and trying to figure out how to fix. Thanks in advance.
const funName = () => {
return (
.........
{data.map((eachData, index) => {
const [endDate, setEndDate] = useState("new Date(eachData.eDate)");
return (
<CustomComponent
key={index}
selected={endDate}
onChange={(date) => setEndDate(date)}
You can't use useState
in map
you need to declare it in top (before return)
const funName = () => {
const [endDate, setEndDate] = useState();
return (
.........
{data.map((eachData, index) => {
return (
<CustomComponent
key={index}
selected={endDate}
onChange={setEndDate}
