I've got useState object like this
export const dataService = () => {
const [data,setData] = useState([
{
dataName:'name1',
dataVisible:false,
dataUrl:'http://localhost:8080/get_document/41gfdg-rewr-432fdsg'
},
{
dataName:'name2',
dataVisible:false,
dataUrl:'http://localhost:8080/get_document/gfd6765-hf34-hgf34'
},
{
dataName:'name3',
dataVisible:false,
dataUrl:'http://localhost:8080/get_document/hgfhbv-dsad-jy675j'
},
{
dataName:'name4',
dataVisible:false,
dataUrl:'http://localhost:8080/get_document/lokg12-jg9d-hgf'
}])
const handleChange = (e) => {
setData(prevState => ({
...prevState,
[e.target.name]: e.target.checked
}))
}
return(
<div>
{data.map((item,index) => {
return(
<Grid>
<Checkbox
name={item.dataName}
onChange={handleChange}
checked={item.dataVisible}
/>
<label>{item}</label>
</Grid>
)
})}
<div>
)
}
I want to update dataVisible in time when I click on specify checkbox. But when I click then this data struct don't update this field but add new field with this target checked. Have any idea to solve this problem. I cant invent direction to this fields...
