如何提交这个 Onchange 表格？ reactjs

Question

how to submit form this Onchange? I don't have a button to fire the form, how to do that? I can't insert routes as it's a component for several clients. I use react hook forms

const handleChange = (e: any) => {
        const avatar = URL.createObjectURL(e.target.files[0])
        setAvatar(avatar)
      };

Did you try this solution using useEffect

 const [avatar,setAvatar] = useState(null); useEffect(() => { if(avatar) handleSubmit(); }, [avatar]); const handleChange = (e: any) => { const avatar = URL.createObjectURL(e.target.files[0]) setAvatar(avatar) }; // suppose that this is this is your handleSubmit function const handleSubmit = () => { // your code goes here };
