I am trying to use useRef as shown below with typescript strict set to On, but I keep getting 'Object is possibly 'undefined'.
const inputRef = React.useRef();
const updateSelectionStart = () =>
setSelectionStart(inputRef.current.selectionStart);
I also tried with this:
const inputRef = useRef<HTMLInputElement>(null);
and
const inputRef = useRef<HTMLInputElement | null>(null);
And nothing.
Any suggestions about how to do it without typescript errors?
Try using typescript optional chaining feature as below:
const inputRef = React.useRef();
const updateSelectionStart = () =>
setSelectionStart(inputRef.current?.selectionStart);
I fixed it by doing this:
const updateSelectionStart = () => {
setCursorPosition(inputRef.current!.selectionStart || 0);
};
