I want to build a self updating filter with checkboxes:
//extract tags to new array
const tags = [...new Set(shooting.map(({ tag }) => tag).flat(1))];
// result: tags = ['wedding', 'couple', 'NSWF'] // <- here undefinded count of tags !
function Test() {
return (
<FilterCheckboxBar
filteredTags={tags} />
);}
export default Test;
FilterCheckboxBar:
interface Filter {
filteredTags: any;
}
function FilterCheckboxBar(props: Filter) {
const [values, setValues] = useState<any>([]); // <- I guess here is something missing
// ----- Handle Checkbox----- // <- or in this one is an error
const handleChange = (e: any) => {
setValues((prevState: any) => {
const [name] = e.target;
return {
...prevState,
[name]: !prevState[name],
};
});
};
return (
<div className="filterbar">
{/* this list my checkboxes */}
{props.filteredTags.map((list: any, i: any) => (
<label key={i} htmlFor={list}>
<input
className="checkbox"
type="checkbox"
name={list}
id={list}
onChange={(e) =>handleChange(e)}
checked={values}
/>
{list}
</label>
))}
</div>
);
}
export default FilterCheckboxBar;
by clicking on one checkbox, my page gets white and in the console this massage comes: Uncaught TypeError: object is not iterable (cannot read property Symbol(Symbol.iterator))
I guess I have to do something with useState
but do not know,how to build this.
