const[data, setDate] = useState({
field1 : [{
f1: "",
f2: "",
}],
field2: [{
f3: "",
f4: "",
}]
})
In the above how I can update and push new element to field1 and field2
You may try the following:
let temp={...data};
temp.field1.push(...);
temp.field2.push(...);
setDate(temp);
const [data, setDate] = useState({
field1: [
{
f1: "",
f2: ""
}
],
field2: [
{
f3: "",
f4: ""
}
]
});
useEffect(() => {
let temp = { ...data };
temp.field1.push({ f3: "" });
setDate(temp);
}, []);
